The Underdrawing, the Sketch, and the Line
What the great masters drew before they painted, why some of them drew nothing at all, and what the relationship between line and wash has produced across six centuries of Western art
The Question That Divides Painters
At some point in the development of every serious watercolorist, the question arrives: do you draw first, or do you paint directly? It is framed, in studios and art schools and online forums, as though it has a correct answer — as though one approach is more disciplined, more advanced, or more authentically of the medium than the other. The debate generates more heat than most technical questions in watercolor, which is itself a reliable sign that the question is the wrong one.
The right question is not whether to draw, but what role the drawn line plays in your working process — and, beneath that, what role you want line to play in the finished painting. These are different questions with different answers for different painters and different subjects. Dürer drew with a precision that modern botanical illustrators still study as the outer limit of observational accuracy. Turner, in his mature work, often painted directly onto paper with no preliminary drawing whatsoever, blocking in compositions from value masses rather than outlines. Sargent used graphite underdrawing selectively — for architectural elements requiring geometric precision, but not for figures, for which he trusted his eye and his brush alone. Rembrandt's pen-and-wash drawings are among the supreme drawings in Western art, works in which line and wash are not separate operations but a single, simultaneous thinking-in-marks.
All of these approaches are valid. None of them is beginner's versus advanced. They are different solutions to the same problem: how to translate observed reality or imagined vision into marks on paper, in a medium that forgives almost nothing.
This article examines the full range of relationships between drawing and watercolor — the underdrawing that guides without constraining, the line-and-wash tradition that treats drawing and painting as equals, the composition principles that underlie both, and the hard-won tips that distinguish practiced knowledge from theoretical understanding. It is a technical article and a historical one simultaneously, because in this area more than almost any other, the technical and the historical illuminate each other directly.
Part One: The Historical Relationship — From Tint to Art
The relationship between drawing and watercolor is, for most of its history, a hierarchical one. Drawing was the foundation, the framework, the serious discipline. Watercolor was the colorist's assistant, added to an existing linear structure. This arrangement was so thoroughly assumed that watercolor was for centuries described not as painting at all but as "tinted drawing" — the color applied to fill in the spaces between lines that an artist had drawn first.
Until the emergence of the English school, watercolor became a medium merely for color tinting outlined drawings or, combined with opaque body color to produce effects similar to gouache or tempera, was used in preparatory studies for oil paintings. This description from Britannica captures precisely the subordinate status of the medium: a servant to drawing, a tool for provisional color notes in preparation for something more serious. The Dutch and Flemish topographers of the 17th century used ink line first and wash second as a matter of professional convention. Botanical illustrators used graphite or silver point first and transparent watercolor second, always.
The line-and-wash technique was practiced in Europe from the Renaissance, and in the early 15th century Cennino Cennini gave detailed instructions for reinforcing a pen drawing with the brush. The technique entered into common use in the 16th century and reached its height in the 17th century in the works of Rembrandt, Claude Lorrain, Nicolas Poussin, and a host of Italian artists.
Rembrandt's line-and-wash drawings represent this tradition at its most intelligent and spontaneous. His reed pen lines — bold, gestural, sometimes scratchy with the pen dragged sideways across the paper — establish the essential forms of figures, biblical scenes, domestic interiors, and Amsterdam landscapes with remarkable economy. The brown bistre or sepia wash applied over or around the pen lines does not color them in; it models the shadows, creates atmospheric depth, and suggests the light that the line alone cannot describe. In the best examples, the line and the wash are genuinely interdependent — neither one complete without the other, both together more than the sum of their parts.
This is the first important distinction in the drawing-watercolor relationship: the difference between line as container (in which wash fills spaces defined by drawing) and line as partner (in which line and wash contribute different and complementary kinds of visual information simultaneously). Rembrandt's wash drawings are partnership drawings. The 18th-century topographical tradition was container drawing. Both have legitimate descendants in current practice.
The transformation of watercolor into an autonomous medium — the English Golden Age, Turner, Girtin, Cotman, Homer — involved, among other things, the progressive liberation of the color from its dependence on preliminary drawing. The great leap: painters began to define form through value and wash rather than through line, using the edge of a wash rather than a drawn outline to establish where one thing ended and another began. This is a fundamentally different understanding of how painting works. It treats the painting as a tonal structure rather than a colored drawing — and it is the foundation of everything the previous articles in this series have described.
But it is not an abandonment of drawing. It is a transformation of what drawing means in the context of the medium.
Part Two: The Underdrawing — What Goes Down Before Paint
The underdrawing in a watercolor serves one or more of three distinct functions: it establishes composition, it provides measuring reference for complex elements, and it guides the placement of edges and values. These three functions are not always equally necessary, and the decision about how much underdrawing to do — and what kind — should be driven by which of these functions the specific subject and approach requires.
Graphite pencil is the most common underdrawing medium, and for good reason. It is erasable, infinitely variable in line weight and tone, compatible with all watercolor washes, and easily controlled. The principal consideration in pencil underdrawing is lead hardness: softer pencils (B through 4B) produce darker, more visible marks that show through transparent washes even when painted over, which can be an asset or a liability depending on the desired result. Harder pencils (H through 4H) produce lighter marks that disappear more completely under darker washes and remain barely visible under light ones.
The practical advice that decades of practice converge on: use the lightest marks that still give you the guidance you need. Underdrawing that is too dark or too detailed creates two problems — it shows through the finished washes in ways that contradict the painted form, and it constrains the painting by making any departure from the drawing feel like a mistake rather than a discovery.
Once you cover pencil with watercolour you will not be able to erase it. Since watercolour is transparent you will also be able to see the mark unless it is a very pale sketch mark and a dark watercolour paint.
This point has important technical implications. The pencil marks you leave in your underdrawing are permanent once the first wash goes down. Marks in areas that will receive only light washes — pale skies, sunlit white walls, fair skin in light — will be visible in the finished work unless they are erased before painting begins. The professional habit is to draw with minimum necessary pressure, erase non-essential marks before painting, and accept that some faint graphite will remain in light areas as part of the painting's fabric. Many painters consider visible graphite marks an asset — evidence of the hand, of the observational process — rather than something to be concealed.
Sargent used graphite pencils to lay down underdrawings on exacting elements such as buildings, and applied graphite lines at the very last, on top of largely finished watercolor paintings, to indicate facial features in figure paintings.
This observation about Sargent's practice reveals something important: the underdrawing and the finish drawing are different operations. The graphite that went down before the first wash served compositional and measurement functions — positioning the architecture, establishing the proportional relationships between elements. The graphite applied over nearly completed watercolor served a different function entirely: adding the finest linear detail (facial features, structural edges) that the brush could not achieve at the required precision. Sargent was using graphite as a drawing tool twice in the same painting, for different purposes, at different stages.
Watercolor pencils offer an interesting alternative for painters who want a guided underdrawing that will dissolve harmlessly into the first wash. A watercolor pencil mark, when wet, releases its pigment and blends into the surrounding wash, effectively disappearing as a line and contributing only a slight color note to the underlying passage. For subjects where the underdrawing will be heavily covered by subsequent washes, watercolor pencil eliminates the concern about permanent pencil marks showing through.
Charcoal was used by some painters — notably for large-scale figure work — as an underdrawing medium because it can be completely removed with a soft brush or cloth after the initial washes have dried. It is, however, incompatible with transparent watercolor in any quantity: carbon particles that remain on the paper contaminate subsequent washes, producing gray-brown contamination in light areas. If charcoal is used at all, it must be thoroughly removed by brushing and light blowing before any paint is applied. The risk is high enough that most professional watercolorists avoid it entirely for underdrawing purposes.
Part Three: The Drawing Media — A Practical Survey
The materials available for drawing in relation to watercolor fall into three categories: those used under subsequent washes (underdrawing media), those used alongside washes as equal partners (line-and-wash media), and those used over completed or partially completed watercolor (overdrawing media). Each category has its own requirements, its own compatible materials, and its own aesthetic implications.
Underdrawing Media
Graphite (pencil): The universal underdrawing tool. Available in grades from 9H (hardest, lightest) through HB (middle) to 9B (softest, darkest). For watercolor underdrawing, H through 2H gives clean, light marks that guide without dominating. The mechanical pencil's consistent line weight suits architectural work; the traditional woodcase pencil's variable pressure suits organic subjects. Both are archivally stable.
Silver point: The Renaissance drawing medium — a silver stylus drawn across specially prepared paper coated with gesso or zinc white. The marks are extremely fine and pale, oxidizing over time from pale gray to warm brown. Used by Leonardo and Dürer for preparatory drawings of the most refined kind. For watercolor underdrawing, silver point produces marks too faint for most purposes but extraordinary for botanical and fine-detail work. The technique requires considerable preparation and practice before it becomes useful.
Watercolor pencil: As described above, the underdrawing medium that dissolves. Available from Faber-Castell (Albrecht Dürer), Caran d'Ache (Museum Aquarelle), and Derwent (Watercolour), among others. The Faber-Castell range is considered the industry standard for quality and color accuracy.
Line-and-Wash Media
Waterproof ink in dip pen: The classic medium of the Rembrandt tradition. India ink (carbon-based, waterproof when dry) applied with a metal nib produces variable-weight lines of extraordinary character — fine on the upstroke, broad under pressure, with the characteristic slight roughness of metal nib on textured paper. The Gillott range of drawing nibs (particularly the 303 and 404) and Brause nibs are the traditional choices. The nib must be cleaned frequently during working to prevent ink buildup that causes blobbing. The waterproof quality of dried India ink means subsequent watercolor washes pass over it without disturbing it — the lines remain permanently crisp beneath however many wash layers are applied.
Pigma Micron and similar technical pens: The modern practical choice for line-and-wash work. Pigma Micron (Sakura) pens use pigment-based archival ink that is lightfast and waterproof when dry, available in multiple nib widths from 0.05mm to 0.8mm. They require no preparation, produce consistent line weight, and are genuinely reliable. For travel sketching and urban sketching in particular, the Micron is the professional standard. The tradeoff is that machine-made lines lack the character variation of dip pen work — a limitation that matters greatly for expressive figure drawing and very little for architectural sketching.
Fountain pen with archival ink: The gentleman's tool. A quality fountain pen loaded with a waterproof archival ink — Platinum Carbon Black, Rohrer & Klingner Salix, or Noodler's Bulletproof series — combines the pleasure of a flexible, comfortable drawing implement with the practicality of a contained ink supply. The key requirement is that the ink must be specifically rated waterproof or water-resistant; standard fountain pen inks are dye-based and will bleed into subsequent watercolor washes. The Lamy Safari with an EF nib is a practical starting choice; the TWSBI Eco or Pilot Custom 74 for more serious commitment.
Brush pen: Japan's contribution to the line-and-wash vocabulary. The brush pen — a felt-tipped or fiber-tipped pen with a brush-like flexible nib — produces lines of the widest possible weight range from a single tool, from hairline to broad stroke depending on pressure. Pentel's Pocket Brush (which uses replaceable cartridges of pigmented ink) is the professional benchmark — loved by urban sketchers, travel watercolorists, and manga artists equally. The Tombow Fudenosuke offers a slightly firmer tip for those who find the full brush too flexible to control initially.
Reed pen: Turner used one. Rembrandt used one almost exclusively. The reed pen — a section of bamboo or cane cut to a writing point — produces marks of a character unlike any metal nib: slightly rough, slightly unpredictable, responsive to changes in the material's moisture in a way that creates organic variation throughout the drawing session. Making your own from bamboo is straightforward and produces a drawing tool that costs nothing and lasts for months of serious use. For painters who find the precision of the Micron limiting and want something more alive, the reed pen is the most direct path to gestural authority in line work.
Overdrawing Media
Graphite over watercolor: As Sargent practiced, final graphite marks over dried watercolor add linear precision where the brush cannot go. Applied with light pressure on a finished or near-finished surface, 2H or 4H graphite leaves marks fine enough for facial features, window glazing bars, and rigging. The dried watercolor surface accepts graphite differently from raw paper — the sizing and pigment create a slightly harder surface that responds better to harder leads. Soft pencils smear on dried watercolor.
Ink over watercolor: The wash-and-outline tradition, reversed. Applying ink lines over completed watercolor passages is the technique used in urban sketching almost universally — it allows the painter to establish loose, expressive watercolor passages first and then organize them with ink line afterward, finding the drawing in the painting rather than constraining the painting with a drawing. Because no subsequent washes are planned, any ink — waterproof or not — is acceptable. Non-waterproof sepia or warm brown inks produce a particularly sympathetic quality over warm watercolor passages, their slight bleeding into the dried surface giving the overdrawing a quality that feels integrated rather than imposed.
Part Four: Composition Basics — The Drawing as Planning Tool
Before the brush touches the paper, before a single wash is mixed, the composition must be established. This is where drawing serves its most fundamental role in watercolor: not as underdrawing for painting, but as the thinking process that determines what the painting will be.
The thumbnail sketch — a small, rough, rapid drawing that establishes the major compositional decisions — is the most important single practice in the pre-painting process. Made at a scale of perhaps 5 × 8 cm, the thumbnail is not a detailed rendering but a notation of the value structure: where the darks are, where the lights are, how the major shapes are arranged, where the eye is meant to enter and travel through the composition. At thumbnail scale, the temptation toward detail is eliminated — the hand can only make large marks, which forces the painter to think in large masses rather than specific features.
The master painters treated compositional drawing as a distinct and necessary discipline. Turner filled dozens of sketchbooks with tiny compositional notations before beginning finished watercolors. Constable made elaborate value studies that established the entire tonal logic of a landscape before he chose his colors. Homer's working process included rapid pencil notation of compositional ideas that was clearly separate from his subsequent observation of the subject.
The rule of thirds is the compositional principle most commonly taught and most commonly misunderstood. Its useful version: divide the picture plane into a 3×3 grid and place the primary points of interest near the intersections of the grid lines rather than at the center or at the edges. Its misuse: treating it as a formula rather than a guideline, rigidly placing every important element on a grid intersection regardless of what the subject requires. The underlying principle — that centered compositions feel static and that the most dynamic placements slightly displace the viewer's expectation — is valuable. The rule as mechanical formula is a trap.
The golden ratio — approximately 1:1.618, the proportional relationship found throughout natural growth patterns and classically considered the most harmoniously satisfying division of a rectangle — has a legitimate place in compositional planning without being the mystical formula some art theory treats it as. Its practical use: horizons, dominant verticals, and primary focal points placed at golden ratio divisions rather than at thirds or halves tend to produce compositions with a slightly more sophisticated balance. Turner's compositional instincts consistently place his primary atmospheric passages at golden ratio divisions. Whether he calculated this or arrived at it through trained eye is a question that cannot be answered — but the result is evident.
The S-curve and the Z-path are compositional devices for directing the viewer's eye through the picture plane rather than to a fixed point. A river, a road, a line of figures that curves through the composition in an S-shape creates a path of visual travel that the eye follows through the entire picture space. The Z-path — used frequently in Sargent's architectural watercolors — moves the eye from a lower-left foreground element through a mid-ground passage to an upper-right distance passage, covering the full spatial depth of the picture in a single visual journey.
Negative space — the areas of the composition not occupied by the primary subject — is as compositionally active as the positive shapes. The watercolorist's specific version of this principle: the reserved whites are not gaps in the composition. They are shapes, as deliberately considered as any painted passage, and their edges define positive forms as much as negative ones. The white of the paper around a dark subject is not absence — it is presence of a specific shape, and that shape must be considered as carefully as the shape of the dark itself.
Value patterns, not subject matter. The most reliable test of a composition's underlying soundness: reduce it to three values (light, mid, dark) and assess the resulting abstract pattern. If the three-value reduction produces a clear, interesting abstract arrangement — with each value occupying a meaningfully different proportion of the picture plane, none of them fragmented into disconnected small shapes — the composition is structurally sound. If the three-value reduction produces a scattered, incoherent arrangement of small shapes, no amount of technical painting skill will rescue the finished work. The composition must be right in value-plan before color is introduced.
Part Five: The Line-and-Wash Tradition — Equal Partners
The tradition of line and wash as a finished artistic statement — not preparatory drawing, not underdrawing, but a fully realized artwork in which ink and watercolor are equally present and equally essential — has its own history, its own masters, and its own working principles distinct from either pure watercolor or pure drawing.
In 13th-century China, artists used transparent ink washes to create delicate atmospheric effects. The line-and-wash technique was practiced in Europe from the Renaissance. The Chinese tradition of ink wash painting — in which the gradations of a single ink produce the entire tonal range of a composition — is the Asian parallel to the European line-and-wash tradition, though the philosophical relationship between them is quite different. The Chinese literati tradition treated the brushstroke itself as the primary expressive unit, with wash value and line occurring simultaneously in the single mark of a loaded brush. The European tradition separated line (pen, with its mechanical precision) from wash (brush, with its fluid breadth) and valued their contrast.
Rembrandt's wash drawings, made primarily in the 1640s and 50s, are the high point of the European tradition. His reed pen lines are never descriptive outlines but structural notations — they indicate where things are without fully describing what they look like, leaving the wash to complete the visual information. In a characteristic Rembrandt wash drawing of a landscape or biblical subject, the line establishes direction and edge, the wash establishes depth and atmosphere, and the white paper provides the light. Three elements, each necessary, none sufficient alone.
The modern inheritors of this tradition are the urban sketchers — a community of painters and drawers who work exclusively on location, in cities and landscapes, in sketchbooks, combining pen line and watercolor wash with a directness and immediacy that is the contemporary equivalent of the 17th-century topographer's practice.
The biggest advantage of this technique is that the design and the composition is fully solved at the drawing step. That is why, when painting in watercolor, an artist can concentrate on colors whilst paying less attention to the drawing.
This is the primary strategic advantage of the line-and-wash approach: the compositional and observational work is done in the drawing phase, leaving the painting phase free to focus entirely on color temperature, value, and wash behavior. For location work in complex urban environments — where the buildings, streets, figures, vehicles, and atmospheric conditions are all competing for attention simultaneously — having the composition locked in ink before the watercolor begins is a significant practical benefit.
The sequence question in line-and-wash work is genuinely open. There's no right or wrong way to create line and wash artwork. Although the order in which you choose to work can have an effect on the finished piece. For example if you use a pen first you tend to end up with a more meticulous, controlled result. The pen lines are usually more dominant when you work this way round. On the other hand if you apply ink over the top of watercolor, the result can be more energetic. You'll be less inclined to draw the entire contour of the subject and you can just use your pens to add some texture and sharpen up a few details.
Both sequences are valid artistic choices with distinct aesthetic results. Ink-first produces paintings in which the drawing is the primary structural language and the watercolor is atmospheric elaboration. Wash-first produces paintings in which the color masses establish the primary visual relationships and the ink line afterward organizes and specifies within those masses. The ink-first result looks like a drawing that has been colored. The wash-first result looks like a painting that has been drawn into — and the character of the drawing changes because the painter is working over an established color context rather than against white paper.
Part Six: When Not to Draw — The Case for Direct Painting
The case for not drawing before painting — for going directly to the brush without any preliminary line — is not a romantic or impulsive position. It is a technically defensible approach with a distinguished historical pedigree and specific advantages that the underdrawing approach does not share.
Turner, in his mature watercolor practice, worked with minimal or no pencil underdrawing. He didn't use to prepare an underdrawing — his compositions are blocked in with washes, as can be seen in many of his unfinished works. The use of pencil underdrawing, which was otherwise common at his time, was found in just very few of his paintings. This is all the more remarkable given the complexity of his compositions — elaborate architectural subjects, multi-ship marine paintings, detailed mountain topography — all established from the beginning through value masses rather than drawn outlines.
The advantages of direct painting are several. First, it forces the painter to think in masses rather than edges — which is the correct way to think about a painting organized around value and atmosphere. Second, it prevents the compositional overcommitment that a detailed underdrawing creates: a direct painting can evolve during the working process in ways that a fully-drawn underdrawing cannot. Third, it trains the eye and hand together, in real time, without the mediation of a drawing phase. This training produces a different kind of observation — more holistic, more attuned to value and mass, less dependent on the linear description of edges.
The practical prerequisite for direct painting is value confidence: the ability to assess the tonal structure of a subject and translate it into wash masses without the guiding structure of a drawing. This is built through the value studies and monochrome exercises described in the shadows and darks article of this series. The painter who cannot yet make a convincing five-value monochrome study is not ready to paint directly from complex subjects. The painter who can make that study with confidence will find direct painting a natural extension of the same skill.
Part Seven: Tips From Experience — What Practice Actually Teaches
The following is a distillation of what experienced watercolorists across the tradition have found — sometimes only after years of contrary practice — to be true about the relationship between drawing and painting. None of it is learnable from reading alone, but all of it is learnable faster by reading and then practicing.
Draw what you intend to paint, not everything you see. The most common failure of the underdrawing is over-inclusion: drawing every detail of the observed scene rather than selecting the elements that the painting requires. An underdrawing is an editing decision as much as an observational one. It commits you to a specific version of the subject before the brush has touched the paper. Draw only what you genuinely intend to paint.
The lightest marks that guide you are better than darker marks that constrain you. A heavy, detailed pencil underdrawing creates a second value structure beneath the painting that competes with the painted value structure. Light marks that are barely visible before painting begins will guide you sufficiently and will not be visible in the finished work.
Erase before painting, not after. Pencil erasing on dry watercolor paper (even with a soft eraser) risks damaging the sizing — the very property that makes the paper behave as it should. Erase unnecessary marks before the first wash, not afterward. Use a kneaded eraser (also called a putty rubber) for its ability to lift graphite without abrading the paper surface.
In line-and-wash, let the line breathe. The instinct in ink-first line-and-wash work is to draw complete, continuous outlines around every form — closed shapes waiting to be colored in. This produces exactly the "tinted drawing" quality that the great line-and-wash tradition transcends. Practice instead drawing lines that start and stop, that imply edges without completing them, that establish structure without closing off forms. The wash, applied afterward, will complete the forms where the line leaves them open — and the result will have more life.
Ink and watercolor belong to each other in terms of scale. Fine ink line and large loose washes in the same painting create a dissonance — the precision of the line and the generality of the wash pull against each other. Match the scale and character of your ink work to the scale and character of your wash work. Tight, fine-nibbed architectural drawing requires controlled wash passages. Bold, gestural brush pen work calls for broad, wet-into-wet washes.
The composition must work without the drawing. Before adding wash to a pen underdrawing, pause and evaluate whether the ink drawing alone makes compositional sense — whether the value structure implied by the drawing's line density and distribution already suggests a coherent tonal arrangement. If it does not, adding color will not rescue it. Correct the drawing first.
Draw the shadows, not just the objects. The most diagnostic drawing exercise for painters: instead of drawing the outlines of the objects in your subject, draw only the shapes of the shadows. This forces the eye to attend to the tonal structure of the scene rather than the symbolic descriptions of its contents, and the resulting drawing — a collection of dark shapes rather than outlined forms — immediately reveals whether the value arrangement of the composition is interesting and coherent.
The thumbnail is non-negotiable. No matter how experienced the painter, no matter how familiar the subject, the five-minute thumbnail that establishes the composition's value logic before the large sheet is touched is never wasted time. The five minutes invested in a thumbnail prevents the hour lost to a failed painting.
Your drawing improves your painting and your painting improves your drawing. This is the one that takes longest to absorb and that experienced painters state most consistently. The painter who draws regularly — not just as underdrawing for paintings but as an independent practice, in sketchbooks, from life, in any medium — develops observational skills, spatial understanding, and mark-making confidence that are inseparable from painting ability. And the painter who paints regularly develops an understanding of value and mass that makes drawing more coherent, more selective, more structurally intelligent. They are not separate disciplines that happen to share a paper substrate. They are the same discipline approached from different directions.
Part Eight: The Sketchbook as Practice Ground
The sketchbook is to the watercolorist what the rehearsal room is to the musician: the place where the work happens that makes the performance possible. Its use as a painting practice is well understood, but its use as a drawing practice — as the daily habit that maintains and develops observational skill independent of any painting ambition — is less consistently pursued.
The specific sketchbook practice most directly beneficial to watercolor painters is contour drawing: drawing the edges and surfaces of a subject without lifting the pen from the paper, maintaining continuous visual contact with the subject (rather than looking at the page), producing a single unbroken line that records the hand's movement as it follows the eye's path around the forms. Contour drawing at first produces distorted, inaccurate-seeming results that become, with weeks of practice, surprisingly precise — because the accuracy of contour drawing is the accuracy of hand-eye coordination, not of copying a mental concept of what the object looks like.
The value of contour drawing for watercolor painters specifically: it trains the eye to follow edges with the same close attention that the brush must give to the edges of washes. The painter whose eye has learned to trace the specific, complex boundary between a lit surface and a shadow surface through contour drawing will paint that edge with more confidence and more accuracy than the painter who has only ever approached it with the brush.
The other sketchbook practice of specific value: gesture drawing — very rapid (thirty seconds to two minutes) drawings of figures, animals, or landscapes that capture movement and mass rather than detail. Gesture drawing forces the hand to work at the speed of perception rather than the speed of description, producing marks that communicate essential visual information with the minimum number of strokes. The relationship to watercolor: the painter who has trained through gesture drawing has a mark-making vocabulary of economy — the ability to suggest rather than describe, to indicate rather than delineate — that is one of the most valued qualities in expressive watercolor work.
The Resolution
The question this article began with — to draw or not to draw, and if so, how — resolves into something more useful than a yes-or-no answer. Drawing and painting are not alternatives in watercolor. They are aspects of a single practice, differently weighted in different approaches and different subjects, but always present in some form.
The painter who draws well draws nothing on the paper before painting. The composition has been drawn, in the mind and in the thumbnail, before the large sheet is touched. The value structure has been resolved. The sequence of washes has been planned. When the brush begins, it moves with the certainty of a painter who has done the drawing work internally — and the apparent spontaneity of the result is the product of that internal preparation, made invisible by execution.
The painter who draws well also, sometimes, draws lines on the paper. Architectural subjects that require measurement. Complex spatial arrangements that need geometric precision. The final facial features of a figure that the brush, moving at the speed of decisive marking, cannot achieve at the required fineness. These lines are tools, chosen for specific tasks, used when they are the right tool and set aside when they are not.
Between these two poles — drawing as internal process and drawing as literal mark — lies the full range of working approaches, from Turner's pure value-mass painting to Rembrandt's exquisite line-and-wash integration to Sargent's selective graphite underdrawing of architectural elements combined with graphite finishing over completed figure passages.
All of them are drawing. All of them are painting. The distinction, in the end, is less useful than the practice that makes both possible.
Next in this series: Masking, Lifting, and Recovering — the techniques of reversal, when to use them, and why the paintings that needed no recovery are almost always the stronger ones.
