How to Store Unfinished Paint by Numbers Projects: Tips Every Young Artist Should Know

Why Storing an Unfinished Paint by Numbers Project the Right Way Matters

When you're working on a paint by numbers project and need to take a break, storing it correctly can make the difference between picking up right where you left off — or starting over. Whether you're a kid managing homework and hobbies or a parent helping out, knowing how to pause a project without ruining it is a skill worth having.

Paint by numbers kits are designed to be completed over multiple sessions, but paint dries out fast and canvases can get damaged if left unprotected. A little bit of care goes a long way in keeping your artwork fresh and ready to finish.

The Biggest Problems with Leaving a Project Unfinished

Before diving into the tips, it helps to understand what can actually go wrong. These are the most common issues young artists run into:

• Dried-out paint pots — Once the lids are left off, even for a short time, acrylic paint starts to dry and becomes unusable.
• A warped or bent canvas — Rolled up loosely or stored under heavy objects, the canvas can crease and make painting harder.
• Smeared or scratched paint — If the painted surface isn't protected, brushing against other objects can ruin your progress.
• Lost materials — Brushes, reference sheets, and paint pots can easily go missing if everything isn't stored together.

How to Properly Store Your Paint by Numbers Project Mid-Work

Here are some simple, beginner-friendly tips that work for kids and adults alike. These habits will help you keep every paint by numbers project in great shape, no matter how long you need to pause.

1. Seal Your Paint Pots Tightly After Every Session

This is the most important step. After you're done painting for the day, close every single paint pot firmly. Even a tiny gap lets air in, and acrylic paint dries quickly once exposed. If a lid feels loose, a small piece of plastic wrap under the lid adds an extra seal.

If any paint has already dried slightly around the rim, gently clean it off before closing — this helps the lid create a proper seal for next time.

2. Store the Canvas Flat and Face-Up

Always keep your canvas flat, never rolled or folded. Place it face-up on a clean, dry surface. If you need to stack items, make sure nothing is resting directly on top of your painted area.

A large folder, a cardboard sheet, or even a clean tabletop works perfectly as a resting place. Keeping the canvas flat prevents warping and protects the paint from cracking.

3. Keep Everything Together in One Box or Bag

Losing a single paint pot or the reference guide can stall your project completely. Use the original kit box — or a zip-lock bag or small storage box — to keep all your materials together in one place.

• All paint pots (open and unopened)
• Your brushes (washed and dried before storing)
• The number reference sheet or guide
• Any extra tools or sponges included in the kit

Keeping everything organized means you can jump right back in without searching around the house.

4. Always Clean Your Brushes Before Putting Them Away

Brushes left with dried paint on them become stiff and difficult to use. After every session, rinse your brushes thoroughly with water until the water runs clear. Then reshape the bristles and let them air dry before storing them.

Clean brushes make a real difference in how your final painting looks — especially in detailed areas where precision matters.

5. Find a Safe, Dry Storage Spot

Once everything is packed up, store your project somewhere safe: away from direct sunlight, heat sources, and moisture. A desk drawer, a shelf, or a dedicated art supplies corner all work well.

Direct sunlight can fade painted areas and dry out paint pots faster, even when closed. A cool, dry spot keeps everything in the best condition possible until you're ready to continue.
