How to Do Paint by Numbers
A Complete Beginner's Guide
From opening the box to hanging the finished painting on your wall. Every step, every tip, and every common mistake covered in one place.
1. Before You Start: What to Check
Before you paint a single stroke, spend 5 minutes preparing. This small investment saves hours of frustration later.
- Open all paint pots and check they are not dried out. If any look thick, add one drop of water and stir. Re-seal immediately after checking.
- Match every number on the chart to its paint pot. Line them up in number order so they are easy to find while painting.
- Unroll the canvas flat and weigh the corners. Use books or anything heavy. Let it rest flat for 20 to 30 minutes before painting if it has been rolled tightly.
- Identify the largest colour sections on your canvas. These are where you will spend the most time. Start mentally planning your painting order.
- Fill a small cup with clean water for rinsing brushes between colours. Have a dry cloth nearby for drying them.
Check your paint consistency before starting
Good acrylic paint for paint by numbers should be the consistency of thick yogurt. If it is too watery it will not cover the numbers. If it is too thick it will streak. A well-made kit will have paint at exactly the right consistency straight from the pot.
2. Setting Up Your Workspace
Your workspace setup directly affects the quality of your finished painting. These are the conditions that make the process smooth and enjoyable rather than frustrating.
Lighting
Good lighting is the single most important factor. The numbers printed on the canvas are small. In dim light they are nearly impossible to read without straining, which leads to mistakes and eye strain. Work in natural daylight where possible. For evening sessions, position a bright lamp above and slightly to the left of your canvas (or to the right if you are left-handed) to avoid casting a shadow with your hand.
Surface
Work on a flat, hard surface. A wobbly or soft surface makes precise brushwork very difficult. A kitchen table, desk, or art board placed on a firm surface are all ideal. If you are working with the canvas rolled out flat, tape the corners down lightly with low-tack masking tape to stop it moving as you paint.
Posture
Sit at a comfortable height with your canvas at a slight angle rather than completely flat if possible. A slightly tilted surface lets you see the numbers more clearly and reduces neck strain during longer sessions. Prop the canvas against a stack of books if you do not have an easel.
Take breaks every 45 to 60 minutes
Paint by numbers is deeply absorbing and many beginners find themselves painting for hours without noticing. Short breaks reduce eye strain, prevent hand cramps, and give you a fresh perspective on how your painting is progressing. Stand up, stretch, and look at your canvas from a distance every hour.
3. Step-by-Step Painting Instructions
Follow these steps exactly and you will produce a clean, professional-looking finished painting from your very first kit.
Start with the darkest colours first
Always paint the darkest shades in your design before the lighter ones. Dark paint bleeds visibly into wet light paint, but light paint bleeding into dark areas is far less noticeable. Beginning with the darks also gives you the outline and structure of your image early, which helps you understand the design and plan your painting order.
Find the sections marked with your darkest colour number (usually deep blacks, dark browns, or navy blues) and fill every one of those sections across the whole canvas before moving to the next colour.
Work one colour at a time across the whole canvas
This is the most efficient and satisfying approach. Choose one colour, load your brush, and fill every section of that colour across the entire canvas before cleaning your brush and moving to the next colour. This way your brush is always loaded with one clean colour and you never waste time cleaning it unnecessarily.
It also builds a satisfying sense of momentum. Watching one colour fill in dozens of sections across the canvas gives you visible progress with every session.
Work from top to bottom
Within each colour, paint sections from the top of the canvas downward. This simple habit prevents you from resting your hand or wrist on still-wet sections as you move across the canvas. Wet paint smears easily and ruins sections you have already completed. Top to bottom always.
Use the right brush for each section size
Match your brush size to the section you are painting. Large background sections need your wide flat brush for quick, even coverage. Standard sections use your medium brush. Tiny detail sections, fine outlines, and edges between two colours use your fine detail brush. Using a large brush on a tiny section almost always results in paint bleeding over the lines.
Apply paint in thin, even strokes
Load your brush lightly, not heavily. A lightly loaded brush gives you control. A heavily loaded brush drips, bleeds, and produces uneven coverage. Paint in smooth strokes that follow the shape of the section. For round sections, paint in small circular motions. For rectangular sections, paint in parallel strokes. Never jab or stipple unless you are adding texture intentionally.
Let each section dry before painting adjacent sections
Acrylic paint on a canvas dries in 5 to 15 minutes depending on how thick your coat is and the temperature in your room. Paint a colour, move to a different area of the canvas, and come back to paint the adjacent sections once the first area is fully dry to the touch. This completely prevents colour bleeding at edges.
Apply a second coat to light colours
This is not optional for light colours. Any colour that is pale (light cream, pale yellow, light pink, soft blue) will almost certainly need two coats to fully cover the printed numbers underneath. Let the first coat dry completely, then apply a smooth second coat using even strokes in the same direction as the first. The numbers will disappear after two coats on virtually every colour.
For extremely pale colours (near-white), mix a tiny amount of white paint into the colour before your second coat to boost opacity.
Rinse and dry your brush with every colour change
Rinse your brush in clean water until the water runs clear, then dry it on a cloth (not paper towel which leaves fibres). A clean, dry brush picks up pure colour from the next pot. A contaminated brush muddies every colour you apply. Change your water when it becomes too dark to see through. Fresh water, clean brushes, clean colours.
4. How to Use Each Brush
Your kit includes three brushes. Using the wrong brush for a section is the most common cause of messy edges and uneven coverage. Here is exactly when to use each one:
Wide Flat Brush
Use for big background areas: sky, large colour blocks, wide landscape sections. Lay paint down quickly in parallel strokes. Covers large areas in seconds. Never use this brush near a boundary between two different colours.
Medium Brush
Your workhorse brush. Use it for the majority of sections in any design. Works for mid-size sections of any shape. Load lightly, use smooth strokes following the section shape, and clean between each colour.
Fine Detail Brush
Reserve for the smallest sections, outlines, facial features, fine lines, and anywhere two colours meet closely. The thinner tip gives you precision control. Load very lightly with just the tip and use short, careful strokes.
Never leave brushes soaking tip-down in water
This bends and permanently damages the bristles, making them fan out and useless for precise work. Always rinse, dry, and store brushes with the bristles pointing upward or laying flat. Good brushes last for many kits if you treat them well.
5. Key Techniques for Clean Results
How to paint clean edges between colours
Clean edges between adjacent colours are what separate a polished finished painting from a rough one. The technique is simple: always paint from the centre of a section toward its edge, not from the edge inward. This way your brush is unloaded and dry by the time it reaches the boundary line, reducing the chance of bleeding into the adjacent section.
For sections that share a boundary with a contrasting colour, switch to your fine detail brush for the final 3 to 4mm at the edge. A lightly loaded fine brush gives you the precision to stay within the lines.
How to paint small, awkward sections
Tiny sections are the most frustrating part of any paint by numbers kit for beginners. The key is patience and a dry brush. Use your fine detail brush, load it very lightly (just the very tip of the bristles), and use a single short stroke to fill the section. If one stroke does not fully cover the section, let it dry and add a second stroke rather than adding more wet paint on top of wet paint.
Keeping your palette clean while working
If you want to pre-open several paint pots at once to speed up your session, cover unused open pots with a damp cloth or plastic wrap to prevent them drying out in the air. Never leave a pot open for more than 20 to 30 minutes without covering it.
Managing drying time to stay in a flow state
The most productive approach to a session is to have two or three colours on the go at once. Paint all the sections of colour A, then immediately switch to colour B while A is drying, then colour C while B is drying, then return to paint sections adjacent to A. This way you are always painting and never waiting for sections to dry.
Photography tip: photograph your progress
Take a photo of your canvas at the end of every session. Seeing the transformation from empty numbered canvas to finished painting is deeply satisfying and motivating. Many crafters share their progress photos in online communities and find it keeps them going through longer projects.
6. Fixing Common Problems
Every beginner encounters at least one of these. Here is exactly how to fix each one:
| Problem | Cause and Fix |
|---|---|
| Numbers still visible after painting | Completely normal. Let the first coat dry fully and apply a smooth second coat. For pale colours, add a drop of white paint to increase opacity before the second coat. |
| Paint looks streaky | Usually from painting too quickly or using too much paint. Let it dry, then apply a thin second coat in even strokes all moving in the same direction. Do not go back over a drying section. |
| Paint bleeding outside the lines | Brush was overloaded. Let it dry completely, then use a fine brush and matching colour to carefully paint over any bleed. Work slowly with just the tip of the brush. |
| Paint dried out in the pot | Add one or two drops of water, seal the lid, shake gently, and stir after 5 minutes. Add water sparingly as too much makes paint translucent and you will need many more coats to cover. |
| Two colours blended at the edge | Painted into a still-wet adjacent section. Let both dry fully. Then repaint the affected area with the correct colour using a fine detail brush. Work from the centre of the section toward the edge. |
| Canvas is wavy or buckling | Too much water in the paint or painting too quickly over large areas. Let it dry completely flat. Place heavy books on top for 30 minutes. The canvas will flatten out once fully dry. |
| Cannot read the numbers on the canvas | Lighting is too dim. Move to a brighter area or add a lamp. A magnifying glass helps with very small sections. A phone torch held at an angle across the canvas makes faint numbers pop. |
| Wrong colour painted in a section | Let it dry completely. Paint over it with the correct colour. Darker corrections over lighter mistakes usually need just one coat. Lighter corrections over darker paint may need two or three thin coats. |

7. Varnishing and Framing Your Finished Painting
How to varnish your completed painting
Varnishing is optional but strongly recommended for any painting you plan to display, gift, or keep long-term. Varnish protects the acrylic paint against UV fading, moisture, dust, and accidental touching.
Step 1: Wait until your painting is completely dry. Allow at least 24 hours after your final coat of paint. Varnishing over damp paint will ruin the surface.
Step 2: Work in a dust-free area. Dust settling into wet varnish creates tiny bumps in the surface. Use a wide, clean, soft brush dedicated to varnishing only.
Step 3: Apply a thin first coat of acrylic varnish in smooth, even strokes all moving in the same direction. Do not go back over areas you have already varnished while they are still wet.
Step 4: Let the first coat dry fully (30 to 60 minutes for most acrylic varnishes). Then apply a second thin coat in strokes perpendicular to the first. Two thin coats protect far better than one thick coat.
Matte vs gloss varnish: which to choose?
Matte varnish gives a classic fine-art look with no reflective glare. Best for portraits and photorealistic designs where you want the painting to look like oil on canvas. Gloss varnish makes colours appear more vivid and saturated, with a slight shine that catches light. Best for vibrant designs and florals. Satin varnish sits between the two for a subtle sheen without full gloss.
How to frame your completed painting
A frame transforms your finished painting from a canvas on a table to a piece of wall art. You have three main options:
- Standard photo frame — buy a frame in your canvas size, remove the glass, and mount the canvas face-forward. Most paint by numbers canvases have a blank border you can trim to fit standard frame sizes. Keep the glass as paint by numbers surfaces are flat and glass does not damage them.
- Stretcher bars — interlocking wooden strips you stretch the canvas over gallery-style. The canvas wraps around the sides with no visible frame, creating a clean floating look popular in modern interiors. Most craft and art supply shops sell stretcher bars in standard sizes.
- Pre-made canvas frames — specifically designed for rolled canvas paintings. These have a slot or channel around the inner edge that the canvas attaches to. Available online in sizes matching common paint by numbers canvas dimensions.
