Paint by number kits come printed on three different surfaces, and the one you get changes how the painting behaves. Canvas board is the middle option: canvas fabric bonded to a rigid card backing. This is what it is good at, what it is not, and how to work on it.
board against canvas sets out where each surface is genuinely better, and it is not the one most people expect.
What Canvas Board Is
A sheet of primed canvas glued to stiff board. It has the surface texture of canvas and the rigidity of card, and it costs less than a stretched canvas because there is no wooden frame under it.
The three surfaces you will encounter:
- Paper or card. Cheapest. Buckles under wet paint and cannot be framed convincingly.
- Canvas board. Rigid, takes acrylic well, drops straight into a standard frame.
- Rolled canvas. What most direct-sold kits use, including ours. It needs stretching or mounting when you finish, but it can be made into a proper framed piece.
Board is the practical choice if you want to paint it and hang it without any carpentry. Rolled canvas gives the better final object if you are willing to do the extra step.
Where the Format Came From
Paint by numbers was conceived in 1949 at the Palmer Paint Company in Detroit. Max Klein ran the company and Dan Robbins drew the early designs, sold under the Craft Master name. Within a few years it was ordinary for the art in an American living room to have come out of a box with numbered pots in it. There is more on that in our piece on vintage paint by numbers.
What You Need
- The printed board, with its numbered sections.
- Acrylic paints, numbered to match. Kits supply these.
- Two or three brushes. The fine one in most kits is the weakest item; a better small round is the single upgrade worth making.
- Water and a cloth.
- A lamp. More important than any of the above.
Board does not need priming. It comes primed, and adding gesso will obscure the printed numbers.
Painting It
- Lay the paints out in number order before you start, and cover the table.
- Begin with the largest sections. Your hand steadies as you go, so leave the small work until later.
- Finish one color completely before opening the next. Less rinsing, less waste, and the open pot spends less time drying.
- Use smooth, even strokes and take the color slightly over the printed line. A hairline of bare board between two sections is what makes a finished kit look like a coloring book.
- Expect a second coat on the pale colors. Let the first dry properly rather than loading the brush.
Two things board does differently from stretched canvas. It does not give under the brush, so pressure translates straight into a harder mark — useful for crisp edges, less forgiving if your hand is heavy. And because it is rigid, thick paint sits proud of the surface rather than sinking in, which is worth using deliberately if you want texture.
Fixing Mistakes
- Wrong color in a section. Let it dry completely, then paint over it. Acrylic is opaque enough to cover almost anything, though a dark color under a light one may need two passes.
- A smudge on bare board. Wipe it with a damp cloth immediately. Once dry, paint over it rather than scrubbing — scrubbing lifts the primer.
- A ridge or blob of dried paint. Sand it back very lightly with fine paper and repaint. This is one thing board handles better than canvas.
- Paint that has gone thick. A single drop of water, stirred in with a toothpick.
Sealing and Framing
Let the finished painting dry for a full day. Acrylic is touch-dry in minutes and cured much later.
A clear acrylic varnish is optional. A satin finish evens out the patchy sheen left by mixing thick and thin passes and protects the surface. Test on a corner first, and never varnish anything that is not completely dry.
Framing is where board earns its keep: it drops into a standard frame with no stretching and no mounting. Choose the frame for the room rather than the painting. Our guide to framing a paint by number canvas covers the options, and if you have a rolled canvas rather than a board, stretching it onto bars is the equivalent step.
Common Questions
How many colors come in a kit?
Usually between 20 and 32. The count is printed on the box and is the most honest measure of how long the kit will take — a better guide than any difficulty label.
Do I need to blend or mix?
No. Every color is supplied to match a number. Blending where two sections meet is optional, and it is the main thing that stops a finished kit looking like a kit.
Should I clean the brush between colors?
Yes, and more often than feels necessary. Acrylic that dries in the bristles is very hard to remove. Rinse well, wipe on a cloth, and use a little mild soap at the end of a session.
Is it suitable for children?
The larger, simpler designs are. Board is a good surface for younger painters specifically because it does not flex or tear, and acrylic washes out of most things while it is wet.
Does It Actually Help?
There is a reasonable research base on art therapy and creative activity, and it is worth reading rather than taking on trust. Two starting points: Role of Art Therapy in the Promotion of Mental Health and Harvard Health on art therapy and pain. Both look at facilitated art therapy rather than kits, and no one has studied paint by numbers specifically.
What painters themselves report is narrower: an hour of focused work with something to show at the end. That is a modest claim and probably the true one.
Kits to Start With
Ours print on rolled canvas rather than board, vacuum-seal the paints, and include an 11 by 17 printed reference so the numbers stay readable. Cabin Fever, Moonrise Song and Morning Ride are three worth a look, or the full catalog. Custom Paint by Numbers makes one from a photograph of your own, and finished pieces are in the customer gallery.
