The difference between a paint by numbers painting that looks amateurish and one that looks genuinely impressive often comes down to technique rather than kit quality. Even a budget kit can produce beautiful results when you apply the right methods.
These ten techniques are gathered from experienced paint by numbers communities, including long-time contributors on Reddit’s r/paintbynumbers and craft forums where serious hobbyists share their methods. Apply them to your next project and you will notice an immediate improvement.
1. Start With the Darkest Colors
Conventional advice says to work light to dark. Experienced paint by numbers artists often do the opposite. Starting with dark colors means you can paint slightly beyond section boundaries, then cover the overlap when you paint adjacent lighter sections. Dark paint under light paint is invisible, but light paint under dark leaves visible edges.
This technique is especially effective around detailed areas like faces, eyes, and fine lines where clean boundaries matter most.
2. Work One Color at a Time
Rather than painting section by section across the canvas, complete all sections of a single color before opening the next pot. This approach saves time on brush cleaning, maintains consistent paint thickness across all sections of one color, and ensures you never run short on a color because you can see how far it needs to stretch.
3. Use the Two-Coat Method
Nearly every paint by numbers painting benefits from two coats. The first coat provides base coverage. After it dries (10-15 minutes for acrylics), the second coat produces even, opaque coverage that fully hides the printed numbers. This is absolutely essential for light colors like white, yellow, and light pink, which are nearly transparent in a single coat.
4. Invest in Better Brushes
Kit brushes are functional but rarely excellent. A small investment in synthetic sable brushes (available at any craft store for $5-10) transforms the painting experience. You need three sizes: a fine round brush (size 0 or 1) for tiny details, a medium round (size 2-4) for most sections, and a flat brush (size 6-8) for large background areas.
Quality brushes hold more paint, release it more evenly, and maintain their shape over multiple uses. Rinse them thoroughly after each color change and reshape the tips while still wet.
5. Master the Paint-to-Water Ratio
Kit paints should be used as-is for most sections. However, understanding when to adjust consistency helps with specific situations:
- Too thick: Paint drags and leaves clumps. Add one drop of water and stir.
- Perfect consistency: Paint flows smoothly from the brush without running. Think melted ice cream.
- Too thin: Paint is watery and transparent. Let the pot sit open for a few minutes to thicken, or add a tiny amount of paint from a similar color.
6. Use a Magnifying Lamp for Small Sections
Detailed kits with many small sections can strain your eyes. A swing-arm magnifying lamp (available for $20-40 on Amazon) combines magnification with bright, even lighting. This is not a luxury item but a practical tool that prevents eye fatigue and helps you paint precisely within tiny boundaries.
7. Paint From Top to Bottom
Right-handed painters should work from the top-left corner downward and to the right. Left-handed painters should work from the top-right corner downward and to the left. This prevents your hand and arm from dragging across wet paint sections. Some experienced painters also place a clean sheet of paper under their painting hand as additional protection.
8. Close Paint Pots Immediately
Acrylic paint dries quickly when exposed to air. Develop the habit of opening only the pot you are currently using and sealing it the moment you finish that color. This single habit prevents the most common complaint in paint by numbers: dried-out paints.
If paint has started to thicken but is not fully dried, add a drop of water and stir gently with a toothpick. For seriously dried paints, add water and let the pot sit sealed overnight, then stir the next day.
9. Blend Adjacent Colors for Realism
For a more artistic finish, lightly blend the boundary between two adjacent colors while both are still wet. Use a clean, dry brush to gently feather the edge where colors meet. This technique softens the hard lines between sections and gives the finished painting a more natural, hand-painted appearance.
This works particularly well on sky gradients, skin tones, and water reflections. Start with subtle blending and increase as you gain confidence.
10. Apply a Protective Varnish
A clear acrylic varnish is the final step that transforms a paint by numbers project into finished artwork. Varnish protects against dust, UV fading, and accidental damage. It also evens out the sheen across the painting, eliminating the patchy appearance that different paint thicknesses can create.
Choose matte varnish for a classic, gallery-style look or gloss varnish for vibrant, saturated colors. Apply two thin coats with a wide, soft brush, allowing each coat to dry completely before applying the next.
The Golden Artist Colors Technical Information page provides detailed guidance on varnishing acrylic paintings, including application techniques and drying times.
Bonus: The Toothpick Technique
For sections so small that even a fine brush feels clumsy, dip the blunt end of a toothpick in paint and dot it into the section. This gives you pinpoint control for areas that might be only a few millimeters across. Many experienced painters keep several toothpicks handy for this purpose.
Frequently Asked Questions
How do I prevent paint from drying out in the pots?
Keep pots sealed tightly when not in use. If painting for extended sessions, only open one or two pots at a time. For partially dried paint, add a single drop of water and stir with a toothpick. Some painters transfer paints to small airtight containers or add wet sponge pieces to the kit lid to maintain humidity.
Should I varnish my finished paint by numbers painting?
Varnishing is highly recommended. A clear acrylic varnish protects against dust, UV fading, and fingerprints. Matte varnish gives a classic art look, while gloss varnish makes colors pop. Apply two thin coats with a wide, soft brush, allowing each coat to dry completely.
How do I fix a mistake in paint by numbers?
Wait for the wrong color to dry completely, then paint over it with the correct color. Acrylic paint is opaque enough that one to two coats will cover most errors. For stubborn coverage issues, apply a thin layer of white gesso first, let it dry, then apply the correct color.
What brushes should I use for paint by numbers?
Most kits include adequate brushes, but investing $5-10 in a set of synthetic sable brushes in sizes 0, 2, and 6 dramatically improves the experience. Round brushes work best for most sections, while flat brushes are better for large areas.
How do I avoid brush strokes showing in the finished painting?
Apply paint in the same direction within each section. Use thin, even coats rather than heavy applications. For very smooth coverage, lightly re-brush wet paint in one direction before it dries. High-quality, well-pigmented paints also produce smoother results than budget paints.
Common Color Challenges and Solutions
White paint looking transparent: White acrylic is naturally less opaque than darker colors. Always plan for at least three thin coats on white sections. Let each coat dry completely before adding the next.
Colors looking different wet vs. dry: Acrylic paint typically dries slightly darker than it looks when wet. This is normal and expected. If you are concerned about color matching, test a small dot on the canvas edge and let it dry before committing.
Metallic or iridescent sections: Some premium kits include metallic paints for special sections. These paints have different flow characteristics than standard acrylics. Use a flat brush for even application and avoid overworking the surface, which can create streaks.
Putting It All Together
Professional-looking paint by numbers paintings are not about talent or expensive kits. They are about patience and technique. Apply these ten methods consistently, take your time with each section, and enjoy the process. Your next completed painting will be noticeably better than your last.
