Watercolor pencils confuse people because they look like colouring pencils and behave like paint. Shade with one and nothing much happens. Touch it with a wet brush and the colour dissolves and floods.
Michele Webber runs through the core techniques here on a single grid of test boxes, which is the sensible way to learn them - draw yourself the same grid and work down it rather than trying any of this on a painting you care about.
Watercolor pencils vs coloured pencils vs pans
A regular coloured pencil is held together with wax or oil, so water beads off it. A watercolor pencil uses a water-soluble binder, which is why it melts under a brush. Pans are the same pigment in a cake. They cover a big sky faster. Pencils win on control and on travel: a few pencils and a waterbrush fit in a coat pocket.
The one thing that causes most bad results
Not enough water. Almost every disappointing wash is a pencil mark that never fully dissolved, so it sits there as a visible line under the colour. The answer is usually more water and a bigger brush, not more pigment.
Which paper
Use watercolour paper, 140 lb (300 gsm) cold pressed. Printer paper is so thin that the fibres swell as soon as they get wet. It buckles into waves, then pills when you brush it again. Mixed-media paper copes with light washes. A sketchbook with thin pages will ripple.
How much water, and which brush
A waterbrush pen holds water in the barrel. Squeeze gently and the tip stays damp, with no jar to knock over. It suits small areas and sketching on the go. For anything bigger, use a round size 6 or 8 dipped in water and blotted once on kitchen paper. You want the brush wet, not dripping.

| What you do | Shade dry paper, then brush water over it | Wet the paper, then draw into it |
| What you get | Controlled washes, crisp edges | Soft, feathered lines that bloom |
| Use it for | Shapes, skies, layering | Backgrounds, flowers, texture |
Layering and lifting
You need fewer pencils than you think. Yellow over blue gives a green you will not find in any tin. Stop at three layers or the paper starts to give up.
To lift, blot a damp area with kitchen paper or a clean, thirsty brush. On a dry area, wet it, scrub lightly and blot. Staining colours will not fully come back.
Giving a starter set
For a December gift, a set of 24 is plenty. Look for soft leads that dissolve fully, lightfastness ratings on the tin, and a set that includes a waterbrush. Add a small pad of 140 lb watercolour paper. Most beginners get stuck because of the paper, not the pencils.
Common mistakes
- Muddy colour. Too many layers, or working into a layer that is still damp. Let each one dry.
- Paper pilling. Thin paper, or scrubbing the same spot. Use heavier paper and fewer passes.
- Too much water. Puddles dry into hard rings. Blot the brush first.
- Pressing hard. Dents collect pigment and dry as a dark line.
