10 mistakes to avoid when starting paint by numbers

Have you just discovered paint by numbers or are you about to start your very first painting? Congratulations ! This creative hobby is a wonderful way to relax, refocus... and create a work of art you can be proud of, even if you're not an experienced artist.

But like any new activity, the beginning can sometimes be tricky. A poorly cleaned brush, paint applied in the wrong place, a crumpled canvas, or a lack of organization can quickly turn this moment of pleasure into a minor frustration.

In this article, we share the 10 most common mistakes made by beginners, along with simple tips on how to avoid them. The goal ? To allow you to fully enjoy the experience and achieve a final result that meets your expectations—or even exceeds them!

✅ 1. Not preparing your workspace properly

We often underestimate the importance of a good environment for painting peacefully. However, a poorly organized space can quickly turn a relaxing activity into a real source of frustration.

  • Before you even open your paint pots, make sure you have:
  • A flat, stable surface (desk, table, or board).
  • Sufficient lighting, ideally natural light or a white lamp.
  • Protection for the table (tablecloth, plastic sheet).
  • A glass of clean water, cotton swabs, or wipes for touch-ups or spills.
  • A support for drying the canvas safely.


A well-designed workspace ensures that you can paint comfortably, without stress or smudges.

🎨 2. Starting with a painting that is too complex

When you first discover paint by numbers, enthusiasm often leads you to choose a very detailed canvas... with dozens of small, tightly packed areas and a multitude of colors. The result: you can quickly feel overwhelmed, lose patience, and give up before you're done.

To get off to a good start, we recommend:

  • Choosing a model with a limited number of colors (24 or 36, for example).
  • Opt for large areas that are easy to fill in, especially if fine motor skills are not your strong point.
  • Avoid highly realistic portraits or overly complex landscapes for your first attempt.


Starting simple doesn't mean uninteresting: many paintings with clean lines offer a beautiful result... and are much more rewarding to complete !

🖌️ 3. Using too much or too little paint

Balance is key! Many beginners apply too thick a layer of paint, thinking they will get a better result. The problem ? It spills over, obscures the fine details, and significantly increases the drying time. Conversely, too thin a layer will reveal the numbers or not cover the canvas evenly.

Here are a few simple tips:

  • Pick up a small amount of paint at a time with the brush.
  • Apply it in an even layer, without pressing too hard or overloading the brush.
  • If the number is still visible after drying, add a second thin layer.


The right amount of paint will ensure a clean, precise result that meets your visual expectations for the final piece.

🖋️ 4. Forgetting to close paint pots

This is a small mistake that can have big consequences ! If you leave the pots open for too long, the acrylic paint will start to dry out in the open air, making it pasty, unusable... or even completely unusable.

To avoid this:

  • Always close the pots immediately after use, even between two areas of painting.
  • Clean the edges of the pot to prevent them from sticking due to dried paint.
  • Store them away from heat and direct light.


Well-preserved paint guarantees that you can finish your painting with peace of mind, without frustration or waste.

🔢 5. Not following the logical order of areas

Painting in any direction you like may seem fun... but it can quickly become a headache. By not following a logical order, you risk:

  • unintentionally mixing colors,
  • putting your hand in an area that is still wet,
  • or losing track of the painting, especially on complex models.


The ideal approach is to:

  • Start at the top of the canvas to avoid rubbing freshly painted areas.
  • Paint areas by color, finishing one color before starting another (allowing adjacent areas to dry in between).
  • Work from left to right if you are right-handed (and vice versa for left-handed people).


This allows you to organize yourself better, save time, and fully enjoy the experience without stress.

🧽 6. Neglecting to clean your brushes

A clean brush is the basis for a good result. However, many beginners forget to clean their brushes properly between each color. As a result, colors mix, the brush hardens, and details become blurred.

Some good habits to adopt:

  • Rinse your brush immediately after each use, especially before changing colors.
  • Use lukewarm water and a small cloth to wipe it gently.
  • Never leave the brush to soak in water for too long, as this will distort the bristles.


Proper care of your tools will extend their life and ensure a clean finish that is true to your work.

🎯 7. Pressing too hard with the brush

When you're just starting out, you sometimes tend to want to “fill in” the box at all costs... even if it means pressing too hard on the brush. However, this mistake can cause several problems:

  • The brush bristles get crushed or deformed,
  • The paint spills outside the lines,
  • The canvas gets damaged, especially if it is paper or a flexible medium.


👉 Tip: it is better to apply several light coats than one thick, aggressive coat. Let the brush glide gently. Good paint-by-numbers is above all a matter of delicacy and precision, not force.

🖼️ 8. Painting without protecting the canvas or surface

All it takes is one clumsy move or a small accident to ruin a painting in progress. Many beginners forget to protect their work surface or even the canvas itself.

Here are some common risks:

  • Paint stains on the edges of the canvas or on furniture,
  • Water or coffee spills that damage the painting,
  • Creases or snags if the canvas is not properly secured.


Best practices:

  • Use a protective tablecloth, old cardboard, or a desk pad.
  • Secure the canvas with tape or place it on a rigid, flat surface.
  • Always keep a clean cloth handy so you can quickly intervene if there is a problem.


Protecting your space also protects your enjoyment of painting.

❌ 9. Not taking breaks

When you start a paint-by-numbers project, it's easy to get caught up in the urge to finish it all at once. The result ? You stay bent over for too long, strain your eyes, make mistakes... and what was supposed to be a relaxing activity becomes a source of tension.

Here's why it's essential to take regular breaks:

  • Your concentration remains optimal,
  • You avoid back, neck, or wrist pain,
  • You resume each session with a fresh, more precise eye.


💡 Tip: try the 20-20-20 rule: every 20 minutes, look up for 20 seconds and focus on a point 20 meters away. And if you feel tiredness setting in, put down your brushes: the painting can wait.

🧴 10. Forgetting the finishing touches (varnish or framing)

You've spent hours painting carefully... but once you've filled in the last number, don't put your work away without showing it off ! Many beginners neglect the finishing touches, which are essential for preserving and enhancing the painting.

Here's what you need to remember:

  • Apply a protective varnish (matte or glossy) to set the colors and protect the surface from dust, moisture, and time.
  • Frame the canvas or stretch it on a stretcher bar for a gallery-worthy finish.
  • If you wish, add your signature or the date for the finishing touch.


✨ Finishing your painting transforms a simple creative hobby into a work of art in its own right. Don't leave your masterpiece unfinished.

💬 Learn by painting, without pressure

Painting by numbers is not meant to be perfect. Above all, it is an invitation to slow down, express yourself, and take time for yourself. So yes, you may make small mistakes at first—and that's perfectly normal.

Every stroke, every pot left open, every spill is part of the learning process and the fun. The important thing is not to paint like a pro, but to feel that little thrill of satisfaction as you watch your work come to life, color by color.

So breathe, have fun, and remember that every brushstroke brings you a little closer to your masterpiece.

🎨 Grab your brushes... and let the relaxation begin !
