What Can I Do with Leftover Paint from Paint by Numbers?
You've finished your last brushstroke, sealed your masterpiece, and stepped back to admire your work. It’s satisfying to see how hours of painting have turned a numbered outline into a colorful piece of art. But then you notice the small paint pots on your table, each with a bit of color left inside. Some are almost empty, while others are still half full. You might wonder: what should I do with all this leftover paint?
Don’t throw those little pots away. They aren’t waste; they’re a bonus for any artist—a free set of quality acrylic paints ready for your next project. With some creativity, you can turn leftover paint into personalized gifts, home décor, practice pieces, or even small artworks. This guide will show you how to use every bit of leftover paint from your paint by numbers kit, from fun craft ideas to smart storage tips, so nothing goes unused.
The Creative Case for Color Recycling
Before we get into project ideas, let’s think about why reusing leftover paint is important. First, it’s just plain fun. Turning a mix of random colors into something new is a creative challenge that keeps the joy of painting going even after you finish your main piece.
There are also practical and ethical reasons to reuse paint. It’s better for the environment because every pot you use again means less acrylic ending up in landfills. Dried acrylic paint acts like plastic and doesn’t break down easily. Using up what you have helps reduce waste and makes the most of your supplies.
Reusing leftover paint also helps you grow as an artist. DIY projects let you experiment without worrying about following a pattern. You can try new techniques, mix colors, and follow your creative instincts. As one expert says, leftover paint lets you "let off steam to your heart's content and relax at the same time." Plus, you’ll create unique, handmade items to keep or give as special gifts.
Small-Scale Creative Projects
Even though your leftover paint comes in small pots, those little amounts are just right for creative projects that can make a big difference.
1. Create Custom Bookmarks
This is one of the easiest and most satisfying projects. Cut a piece of sturdy cardstock or watercolor paper into a bookmark shape. Paint it with abstract patterns, stripes, or small flowers using your leftover paints. Punch a hole at the top and add a tassel made from thread or ribbon. You’ll have a lovely handmade gift for a book lover or a treat for yourself. For extra durability, laminate the bookmark after the paint dries to protect it and give it a polished look.
2. Decorate Small Objects
Add some color to everyday items around your home. Turn a plain wooden box into a keepsake chest, or paint a smooth stone to use as a garden decoration. Give a terracotta pot a fresh look with patterns or color bands. Even a simple phone case can become unique with a few coats of leftover paint. You can also upcycle small tables, shelves, picture frames, vases, baskets, candlesticks, coasters, and wooden boxes with your extra paint.
3. Paint a Miniature Canvas Series
Small canvases, like 3x3 or 4x4 inches, are great for using leftover paint. Try making a set of three or four abstract paintings with the same colors from your kit. When you hang them together, they create a modern, unified piece of wall art. This project is especially satisfying because you’re making original art, not just following a pattern. Using the same colors helps the series look balanced and connected.
4. Craft Personalized Gift Tags
Make your gifts extra special with handmade gift tags. Use leftover paint to decorate simple cardstock tags for birthdays, holidays, or any occasion. Paint a small flower, a geometric shape, or just add a colorful border. These little touches show you care and turn any gift into something memorable.
5. Enhance Greeting Cards
Give a store-bought greeting card a personal touch by adding paint. Try a simple border, a small abstract design in the corner, or a tiny icon that fits the occasion, like a heart for an anniversary or a candle for a birthday. These small changes make the card more special, and the recipient will notice your extra effort.
6. Practice Abstract Techniques on Paper
Leftover paint is great for experimenting without any pressure. Use thick paper or a sketchbook to practice blending and texture techniques. Play with how the colors mix, and don’t worry about making mistakes. Try wet-on-wet blending, dry brushing, or layering colors to see what happens. This practice will help you improve for your next paint-by-numbers kit.
7. Touch Up Household Items
Since paint-by-number kits use strong acrylic paint, the leftover paint works well for small touch-ups at home. Fix a scuffed picture frame with a bit of matching color, or restore a chipped ceramic figurine. You can also refresh faded spots on wooden decorations. Take a look around—there are probably a few things in your home that could use a little paint.
8. Upcycle Furniture and Larger Pieces
If you have a lot of leftover paint, maybe from several kits, try upcycling furniture. Give a small table, stool, or chair legs a fresh coat of color. You can also paint shelf edges, drawer fronts, or trim. This is a fun way to get creative and make unique, useful pieces for your home.
9. Create a Wall Mural or Accent Design
If you’re feeling ambitious, use leftover paint to make a small wall mural or accent design. You might need to combine paint from several kits for this project. Use a projector to trace a design on the wall, then fill it in with your colors. This turns a plain wall into a unique mural that adds personality to your space.
10. Make Paint-by-Numbers-Themed Party Decorations
For a fun party idea, make paint-by-numbers-themed decorations. Turn a simple design into a large template, print it on poster paper, and set it up as a group painting activity. Give guests small brushes and leftover paint so everyone can add to the artwork. You’ll create a memorable experience and a special piece of art made by your friends and family.
11. Decorate Candles with Dip-Dye Technique
Try this creative way to decorate plain candles. Pour leftover paint into small bowls, making a layer a few centimeters deep. Hold a candle by the wick and dip the bottom into the paint. Let the extra paint drip off, then hang the candle to dry. You’ll get a candle with a colorful base. For a layered effect, dip the candle in different colors, letting each layer dry before adding the next.
Storing Leftover Paint for Future Use
If you’re not ready to start a new project right away, store your leftover paint properly so it stays fresh for months or even years. Unopened acrylic paint can last up to 10 years if stored well, and opened paint should last about 2 years with good care.
The Essential Storage Principles
To keep your paints lasting longer, store them tightly closed, out of direct sunlight, and in a cool, dry spot. Keep the jars upright and organized to avoid spills and leaks.
Here are the key steps for optimal storage:
Clean the Rim: Before closing any paint pot, wipe off any paint from the lid threads and rim. Paint left on the rim can stop the lid from sealing well and cause the paint to dry out too soon.
Seal Completely: Always screw the lid on tightly. Even a small gap can let in air and ruin the paint. For extra protection, put a piece of plastic wrap over the opening before closing the lid. This adds another layer to keep air out.
Consider Transferring to Smaller Containers: If you have just a little paint left in a big pot, move it to a smaller airtight container. Less air inside means the paint stays fresh longer. Small glass jars, mason jars, or plastic containers work well. Paint lasts longer when the container is full and there’s less air.
Label Everything: Label your paint containers with the color number, name, and date. You can also put a dab of paint on the lid for easy identification. This helps you find the right color quickly when you come back to your paints later.
Mind the Temperature: Keep your paint containers where the temperature stays between 60 and 80°F (15-27°C). Avoid places that get too hot, cold, or sunny, and keep them away from heaters. A cool, dry shelf or drawer works best.
Store Upright: Always keep paint pots and jars standing up. If you store them on their sides, they might leak or the paint could dry around the lid, making it hard to open later.
Reviving Dried or Thickened PaintEven if you store it well, acrylic paint can get thick over time. If you open a pot and the paint is thick, sticky, or a bit dry, you can usually bring it back to life..
Add Water Sparingly: Start by adding just 1 or 2 drops of clean water to the paint. Stir well with a toothpick or the end of a brush. Keep adding water one drop at a time and mix after each drop until the paint is smooth again. Don’t add too much water at once—if you use about 30% water to paint, it will weaken the paint and make it too thin.
Use a Flow Improver: For even better results, try an acrylic flow improver instead of just water. Water can weaken the paint, but a flow improver helps the paint spread smoothly and keeps the colors strong. This is especially useful if your paint is thick or sticky.
Know When Paint Is Beyond Saving: If the paint has turned into a hard lump, it can’t be saved. Once the acrylic binder is fully set, no water or medium will make it usable again.
Mixing and Blending Leftover Colors
Your leftover paints can be mixed together to create entirely new colors. This is especially useful if you want to use the paint for a freeform project where exact color matching isn't required.
Start with Small Amounts: When mixing colors, use just a little of each paint at first. That way, you won’t waste paint if the mix doesn’t turn out right. Once you get the color you want, you can make more.
Keep Notes: If you mix a color you really like, write down the amounts you used so you can make it again. This is helpful if your project will take more than one painting session.
Use a Palette: Squeeze or scoop small amounts of different Use a Palette: Put small amounts of your leftover colors on a palette. A paper plate, wax paper, or an artist’s palette all work. Use a clean brush or palette knife to mix and blend the colors. Create a Unified Palette: If you have leftover paints from different kits, sort them by color family, like blues or greens. This makes it easier to find the right shade for your next project. efforts to use up every drop, there may come a time when you need to dispose ofEven if you try to use every drop, sometimes you’ll need to throw out leftover paint. Maybe it’s dried out and can’t be saved, or you just have too much. It’s important to dispose of acrylic paint the right way to protect the environment.TNever Pour Down the Drain: Don’t pour acrylic paint down the sink, drain, or toilet. It can clog pipes and add microplastics and chemicals to the water system.s to let it dry out completely. Remove the lid from the paint pot and leave it open in a well-ventilated area until the paint has hardened into a solid. For faster drying, you can pour the paint onto a piece of cardboard or newspaper and let it dry. Once fully hardened, the dried paint and its container can be disposed of with regular household traUse a Paint Hardener: For bigger amounts of leftover paint, add a paint hardener from the hardware store or use sawdust, cat litter, or shredded newspaper. Mix it in and leave the lid off until the paint is solid. Then you can throw it away.aCheck Local Regulations: Some places have special rules for getting rid of paint. Check with your local waste authority to find out what to do. Many areas have special collection days for hazardous waste, including paint.ing.
