How to Begin a Watercolor Sketchbook

The single biggest cause of early disappointment is thin paper. Ordinary drawing paper cockles the moment a wet wash lands on it. Look for a sketchbook whose pages are made for watercolor, usually around 300 gsm, and ideally cotton or part cotton. Heavier paper takes water without buckling, lets you lift colour back off, and survives a second layer. A small book of good paper beats a large book of bad paper every time.

Watercolor paper comes smooth, lightly textured or rough. Smooth suits fine detail and pen work; the middle texture, often called cold press, is the usual all-rounder; rough breaks the brushstroke up and suits skies and foliage. None is better than the others, but changing constantly makes it impossible to learn what your paint does. Choose the middle texture first, fill one book with it, then try another surface if you want to.

Beginners buy forty colours and use six. A small tin of pans with a warm and a cool version of each primary, plus one earth colour, will mix almost anything you meet outdoors, and mixing is how colour sense is built. Pans are easier to carry than tubes and need no squeezing with cold hands. Buy artist-grade if you can afford a few pans rather than student-grade if you can afford many.

One medium round brush that comes to a point will do nine tenths of the work, because the belly holds water for washes and the tip draws a thin line. Add a water brush, the kind with a squeezable reservoir in the handle, for painting on trains and benches where a jar is impractical. Test a round brush by wetting it and flicking it once; if the tip splits or curls, it will fight you on every edge.

Put the book, tin, two brushes, a pencil, a cloth, a small water bottle and a collapsible cup in one bag and leave it by the door. A clip for holding pages down in wind is worth more than most accessories. The kit should be light enough that taking it costs you nothing, because every gram you add is a reason to leave it at home on the day you would otherwise have painted.

Prop the book at a slight angle, load the brush fully, and draw one horizontal band across the top. A bead of wet paint will gather along the bottom edge; pick it up with the next stroke and carry it down the page. Work quickly and do not go back into a band that has started to set. A wash that dries evenly is the foundation of skies, walls and water, and it is mostly about keeping that bead moving.

Wet an area with clean water until it shines, then touch a loaded brush into it and watch the pigment spread on its own. This is the wet-on-wet technique, and it gives the soft bleeding edges that make watercolor look like watercolor: clouds, distant trees, shadow under a wall. You steer it by how wet the paper is and how much pigment you load, not by brushing it about. The less you interfere, the better it behaves.

Now let the page dry completely and paint the same shape again. Wet-on-dry gives a crisp edge, which is what reads as a building, a branch or a window. Most pages need both: soft edges where things recede, hard edges where you want the eye to stop. Painting the two versions side by side on one page teaches the difference faster than any amount of reading about it.

Watercolor is semi-transparent, so the white of the paper is what gives a painting its light. Highlights are usually not painted on; they are the parts you deliberately leave unpainted. Before you start, decide which three or four small areas will stay bare, then paint around them. This feels awkward at first and it is the habit that most quickly makes a page look like a watercolor rather than a coloured-in drawing.

Most spoiled pages are spoiled by impatience. A second wash laid onto a half-dry first one lifts the colour underneath and leaves a cauliflower-shaped bloom. Touch the back of a finger to the page: if it feels cool, water is still evaporating and the page is not ready. Use the waiting time to mix the next colour, sharpen the pencil or start a second small study on the facing page.

Set a small target: one subject, fifteen minutes, one page. Short sessions beat occasional long ones because they are easy to start and they leave you wanting to continue. Paint what is in front of you rather than planning something worthy: a mug, a window ledge, the corner of a room. A book filled with fifty quick studies teaches far more than three careful paintings and a hundred blank pages.

Outdoors is where sketchbooks earn their keep, and it needs only a little planning. Sit in shade so the page is not dazzling and the wash does not dry before you can move it, clip the pages against wind, and keep the water where you cannot kick it over. Work small outside; a half page finished beats a full page abandoned when the light changes or it starts to rain.

Add the date, the place and the weather in a corner of each page. The notes turn a pile of studies into a record you can learn from, because you can see what you painted in flat light and what you painted in sun. Conservation guidance for works on paper is to use pencil rather than ink for any inscription, and to write only when the paper is on a hard surface so the writing is not embossed through.

Handle the book with clean, dry hands and keep food and drink away from it, which is standard practice for anything on paper. Grease from fingers and splashes of coffee are permanent in a way that a bad painting is not. Let a page dry completely before closing the book, dry your hands on a cloth kept for the purpose, and avoid tape, rubber bands and paper clips, all of which mark and tear paper over time.

Watercolor pigments fade, and paper yellows and becomes brittle. Store finished books somewhere cool and relatively dry, around thirty-five percent relative humidity, away from radiators and vents, and out of direct or intense light. Avoid attics and basements, where leaks and swings in temperature do the damage. If you want to keep a page for decades, an acid-free folder or box is a cheap insurance policy.
