Get Professional Results: 20 Paint by Numbers Pro Tips
If you’re new (or returning) to paint-by-numbers, this guide packs practical paint by numbers tips—covering setup, blending, brush care, finishing, and even the meaning and history behind the hobby. For comprehensive guidance, check out our complete paint by numbers guide for adults, and if you need step-by-step instructions for getting started, see our detailed how to paint by numbers tutorial.
1) Quick start: what you’ll need (and what’s in a kit)
Most modern kits include a pre-printed, numbered canvas, premium acrylic paints, brushes, step-by-step instructions, and a DIY frame—so you can begin immediately. Paintby.ai kits include exactly that, and you can generate unlimited AI images before ordering to get the perfect design. Free worldwide shipping is included.
Optional nice-to-haves: table easel, two water cups (rinse & clean), paper towels, painter’s tape, daylight lamp, a fine detail brush, and a light pad for tiny sections. If you're unsure which kit to start with, our guide to choosing the right paint-by-numbers kit covers everything from canvas materials to size considerations.
2) Setup & workflow that prevents mistakes
- Flatten & mount the canvas (frame, board, or easel) so tiny shapes don’t warp.
- Work top-to-bottom, left-to-right (reverse if left-handed) to avoid smudging wet areas.
- Close paint pots between colors; acrylics skin over fast. A damp paper towel over open pots slows evaporation.
- Two-cup method: one cup to rinse, one with clean water to re-hydrate bristles—keeps edges sharp.
- Tackle large, darker blocks first; finish with light tones once most numbers are already covered.
Understanding the proper setup is crucial for success. This methodical approach prevents most of the common paint-by-numbers mistakes before they occur, saving you time and frustration throughout your painting journey.
3) Coverage 101: hide numbers and lines cleanly
Light colors (yellows, pastels) can show numbers through the first coat. Try:
- Two thin coats of the target color (let layer one fully dry).
- Spot-prime stubborn digits with white acrylic or gesso, then paint.
- Detail tools: a fine liner brush or (carefully) a white gel pen before painting—test first to avoid halos.
Pro tip: paint up to the edge, let it dry, then “meet in the middle” from the adjacent color to create a clean, hairline seam—no ridges. The choice of canvas versus paper materials can significantly impact coverage quality, with canvas typically providing better paint adhesion and hiding power.
4) Blending made easy (and when to use each)
Acrylics dry quickly, so match technique to your goal:
- Wet-into-wet: blend two neighboring colors before they dry for smooth gradients (skies, sunsets). Work small areas; a light mist can extend open time.
- Glazing: mix a little acrylic glazing medium with paint and layer thin, transparent passes to tint and unify areas without losing detail.
- Dry-brush: with almost-dry paint, feather edges or add texture (fur, grass, wood grain).
Avoid over-thinning with water. For heavy thinning and smoother blends, switch to acrylic mediums to maintain paint strength and reduce streaking.
5) Brush care that keeps edges crisp
- Rinse often while painting and clean with mild soap + cool water immediately after; never let acrylic dry in the ferrule.
- For stubborn residue, a dedicated brush cleaner/conditioner helps restore points.
- Pull, don’t push the brush; keep paint out of the ferrule to avoid splaying.
- Store brushes horizontal or bristles-up once dry to maintain shape.

6) Pro finishing: fixes, varnish & framing
- Edge clean-up: when colors are dry, re-establish crisp borders with a slightly thinned version of each color (one pass, light pressure).
- Varnishing (optional): a removable varnish protects from UV/dust and unifies sheen. Consider an isolation coat first for future safe removal; choose satin/matte to reduce glare.
- Frame & display: a simple float or the included DIY frame finishes the piece. (Paintby.ai kits include a DIY frame in the box.)

7) Paint-by-numbers meaning & a short cultural history
Paint-by-numbers democratized painting in the 20th century—packaging the studio process into numbered steps so anyone could make art. Early commercial kits popularized the idea that creativity is teachable by sequence. Today, the format thrives for mindfulness, skill-building, and accessible creativity—and with AI, you can design a subject that’s personally meaningful before it ever becomes a kit.
This evolution from simple hobby kits to sophisticated artistic tools reflects the growing appreciation for accessible creativity. Modern practitioners often combine these fundamental techniques with advanced methods, creating works that transcend the traditional boundaries of paint-by-numbers art.
8) FAQs
How do I keep paints from drying out mid-session?
Work with one or two open pots at a time, close lids promptly, and place a damp towel over opened pots to slow evaporation. Short breaks? Cover your palette and brush with plastic wrap.
My light colors look streaky—what now?
Let layer one dry fully, apply a second thin coat, or spot-prime with white/gesso first.
Should I use mediums or just water?
A splash of water is fine; for heavy thinning or glazing, use acrylic medium to maintain film strength and achieve smoother blends.
Do I have to varnish?
Optional. Many artists do for protection and unified sheen; if you varnish, consider an isolation coat first.
