17 Best Bottle Cap Craft Ideas
Plastic bottle caps are among the things most people toss in the bin without a second thought. But with a bit of creativity, they can turn into colorful home decor, little toys, thoughtful gifts, and even products you could sell at a craft fair or online if you get into it seriously.
The best part is that bottle cap crafts are cheap, beginner-friendly, and work well for both kids and adults. Most projects only need basic craft supplies like glue, paint, and a handful of simple tools you already have somewhere in a drawer.
If you’ve been saving up plastic bottle caps in a jar without knowing why, or you’re just after an easy recycling project to try, here are 17 of the best bottle cap crafts that are fun to make from start to finish.
Why Make Crafts with Plastic Bottle Caps?
Bottle caps are durable, lightweight, waterproof, and available in what feels like every color imaginable depending on which drinks you’ve been buying. That combination means you can build colorful crafts without spending much on raw materials.
They’re also small enough to store easily, which makes them convenient for anyone crafting in a smaller space like an apartment or a shared room. Since a lot of these projects call for dozens of caps at once, it’s a great way to reuse something that would otherwise just end up sitting in a landfill somewhere.
Whether you’re crafting purely for fun, decorating your own home, or building out handmade products to sell, plastic bottle caps offer a surprising amount of possibility once you start looking at them differently.
1. Bottle Cap Flower Wall Art
One of the easiest and most popular bottle cap crafts out there is colorful flower wall art. Arrange bottle caps into flower shapes, one cap sitting in the center with several more arranged around it as petals. Glue everything onto a wooden board, canvas, or a piece of thick cardboard, then paint the background to match whatever room it’s going into.
You can build a single large flower as a statement piece or combine dozens of smaller flowers into a full garden scene covering the whole board. This project looks great in craft rooms, out on a patio, in a kid’s bedroom, or as part of a classroom display. Adding painted stems and leaves in between the flowers makes the whole piece more eye-catching once it’s finished.
2. Bottle Cap Mosaic Picture
Bottle caps are perfect for building colorful mosaic designs without needing actual ceramic tiles. Instead of tile, just arrange bottle caps to form pictures, geometric patterns, hearts, animals, or even a small landscape scene, depending on your patience level.
Mount the finished design onto plywood or a canvas using a strong adhesive that’ll hold everything in place long-term. Because bottle caps already come in so many different colors, you can often build impressive artwork without needing to paint a single one.
Larger mosaic pieces are popular as outdoor decorations and can also be sold as unique handmade wall art if you’re building up a product line.
3. Bottle Cap Coasters
Bottle cap coasters are practical and stylish once they’re finished. Arrange the caps in circles, squares, or a hexagon pattern before attaching them to a base made of cork, felt, or thin wood.
You can leave the caps in their original colors for something bold and playful, or spray paint them a uniform color for a more modern, cohesive look. Add a waterproof sealant over the top to make the finished coaster easier to wipe clean and more durable against daily use.
These make inexpensive handmade gifts and tend to do well at local craft fairs where buyers appreciate something a bit unexpected.
4. Bottle Cap Wind Chime
Turn a handful of colorful bottle caps into a cheerful outdoor wind chime with just a bit of assembly. Punch small holes through each cap and thread them onto fishing line or a strong piece of string. Attach several strands to a wooden ring, an embroidery hoop, or even a small tree branch as the base.
Mix different cap sizes and colors together to create movement and visual interest once it’s hanging and catching the breeze. Add beads or small bells strung between the caps for a bit of extra decoration and sound.
Hang the finished wind chime on a porch, out on a balcony, or from a garden tree where it can move freely.
5. Bottle Cap Garden Markers
If you’re into gardening, bottle caps make excellent little plant markers for very little cost. Glue each cap onto a wooden stick, a bamboo skewer, or a plain popsicle stick, then write out the plant name using a permanent marker or a paint pen.
Different colored caps can represent different vegetables, herbs, or flowers, which makes keeping your garden bed organized a lot more intuitive at a glance.
These markers are waterproof, fully reusable season after season, and more colorful than the plain wooden labels you’d normally pick up at a garden center.
6. Bottle Cap Picture Frame
Decorate a plain wooden picture frame with a scattering of colorful bottle caps to give it a fun, recycled look that stands out on a shelf.
Arrange the caps randomly across the frame’s border, or work out a repeating color pattern if you want something a bit more deliberate-looking. You can even flatten some of the caps slightly with gentle heat if you want a bit of textural variety in the finished piece.
This simple craft transforms an otherwise cheap frame into a personalized decoration that’s perfect for displaying family photos or a child’s artwork.
7. Bottle Cap Mini Turtle
Bottle caps can become adorable little turtles with barely any effort at all. Use one larger cap as the shell, then cut out the head, legs, and tail from craft foam or felt separately. Glue everything together and add a pair of googly eyes for a playful finish.
Paint colorful patterns onto the shell if you want every single turtle in your batch to look a little different from the last.
These small crafts are great for kids, work well as a classroom project, make cute party favors, or can just sit around as miniature decorations on a shelf.
8. Bottle Cap Christmas Ornaments
Plastic bottle caps make cute Christmas ornaments once you dress them up a bit. Decorate them as tiny snowmen, Santa faces, Christmas trees, reindeer, or little wreaths using paint, ribbon, pom-poms, and a bit of glitter.
Attach a small ribbon loop to the top of each one so they’re ready to hang straight on the tree once they’re finished.
These ornaments are inexpensive to make in bulk and work well for holiday craft fairs, school events, or as small handmade gifts to hand out during the season.
9. Bottle Cap Fish Decoration
Create colorful fish by gluing several bottle caps together to build out the body shape, then adding fins cut from foam sheets or cardstock along the sides.
Paint on scales, stripes, or dots to give each fish its own unique look and personality. Hang the finished fish from a length of fishing line to build a fun ocean-themed mobile or wall decoration for a room.
This is an excellent summer craft for kids and works especially well in a beach-themed bedroom.
10. Bottle Cap Pencil Holder
Transform an empty tin can or a cardboard tube into a unique pencil holder by covering the outside surface with colorful bottle caps.
Arrange the caps neatly in rows for something clean and organized-looking, or mix up the colors freely for a more playful, chaotic appearance depending on your taste. Finish with a clear sealant over the top if you want a bit of extra shine and protection.
The finished organizer ends up sturdy enough to hold pencils, paintbrushes, scissors, or makeup brushes while giving an old, boring container a completely brand new look.
11. Bottle Cap Ladybugs
Bottle cap ladybugs are among the simplest crafts on this entire list to make. Paint the caps a bright red, add on a few black spots once that’s dry, and attach a pair of small googly eyes to finish the face.
Glue a magnet onto the back to turn them into refrigerator magnets, or use them as garden decorations instead by attaching each one to a wooden stake pushed into the soil.
Because they come together so quickly, these are perfect for beginners and a great choice for a children’s craft session that doesn’t need much supervision.
12. Bottle Cap Keychains
Bottle caps can become colorful handmade keychains with very little effort required on your part.
Decorate each cap using paint, stickers, tiny printed photos, initials, pressed flowers, or a bit of resin poured over the top, then attach a keyring through a small hole drilled into the cap.
Personalized keychains like these are easy to customize for birthdays, school events, party favor bags, or a handmade gift shop if you’re selling regularly.
13. Bottle Cap Animal Faces
Turn bottle caps into adorable little animal faces like bears, cats, pandas, frogs, owls, foxes, or lions with just a bit of paint and a few small additions.
Paint each cap first, glue on ears cut from felt or foam, and add a pair of googly eyes to bring the whole character to life.
These can be used as magnets, tucked into classroom decorations, added onto greeting cards as embellishments, or hung up as part of a child’s room decor.
14. Bottle Cap Candle Holder Decoration
Glue bottle caps around the outside of a plain glass candle holder or a battery-operated candle base to build a colorful decorative centerpiece for a table.
Arrange matching colors together for a clean, cohesive design, or mix bright colors freely for something more playful and eclectic-looking.
Since plastic should never come into contact with an actual open flame, only use this particular design with LED or battery-powered candles for safety’s sake.
15. Bottle Cap Tic-Tac-Toe Game
Create a reusable travel game using bottle caps as your playing pieces instead of buying something premade.
Paint five caps with an X symbol and five more with an O symbol. Draw out a tic-tac-toe grid on a small wooden board or a fabric pouch where the caps can be stored safely once the game’s finished.
This fun little craft is easy for kids to put together themselves and works really well as a simple handmade gift for another child.
16. Bottle Cap Decorative Tray
Upgrade a plain wooden serving tray by decorating the base with a scattering of colorful bottle caps arranged however you like.
Arrange them into patterns, stripes, flower shapes, or just a random mix of colors before securing everything down with a strong adhesive. Cover the whole design with a layer of clear epoxy resin afterward for a smooth, durable surface that’ll hold up to daily use.
Decorative trays like this are popular home decor items and can often sell quite well at a local market once people see the finished piece in person.
17. Bottle Cap Fridge Magnets
One of the easiest projects on this entire list for a beginner is making bottle cap magnets.
Decorate the caps with painted designs, short inspirational words, flowers, tiny printed photos, scrapbook paper, or small stickers, then glue a magnet firmly onto the back of each one.
They’re inexpensive to make in large batches and work well for gifts, craft fairs, school fundraisers, or even small souvenir shops looking for something locally made.
Basic Supplies You’ll Need
Most bottle cap crafts only call for a handful of inexpensive supplies to get going. Besides clean plastic bottle caps themselves, keep a hot glue gun, some craft glue, acrylic paint, paint brushes, permanent markers, scissors, felt sheets, foam paper, ribbon, googly eyes, magnets, wooden sticks, fishing line, and a clear sealant somewhere within reach.
It’s also worth sorting your bottle caps by color before you start a project. This makes designing patterns and picking out matching colors so much easier once you’re sitting down to build something.
Tips for Making Better Bottle Cap Crafts
Wash your bottle caps thoroughly before crafting with them to rid any sticky drink residue. Let them dry completely before you move on to painting or gluing anything.
Use a strong adhesive like hot glue for projects that need a bit of extra durability to hold up over time. If you’re planning to display any of these crafts outdoors, apply a weather-resistant clear sealant to help protect the colors from fading in the sun.
Collect bottle caps in a range of colors rather than relying on painting every single one from scratch. The natural factory colors often end up brighter and more durable than a coat of craft paint anyway.
And finally, don’t be afraid to combine bottle caps with other recycled materials like cardboard, wood, glass jars, popsicle sticks, or fabric scraps. Mixing materials together tends to result in more creative, professional-looking finished crafts than sticking to just one material alone.
Can You Sell Bottle Cap Crafts?
Yes. A lot of bottle cap crafts sell well because they’re affordable, colorful, and built from recycled materials that appeal to eco-conscious buyers. Items like fridge magnets, coasters, wall art, picture frames, Christmas ornaments, decorative trays, and keychains are especially popular with shoppers looking for eco-friendly handmade gifts rather than mass-produced ones.
If you’re planning to sell your work, focus on neat workmanship, strong glue that’ll hold up over time, and attractive color combinations that catch the eye. Selling matching collections instead of individual pieces can also increase the overall value of each sale. Local craft fairs, school markets, gift shops, and online marketplaces are all good places to reach potential buyers once you’re ready.

Bottle cap crafts prove that you don’t need expensive supplies to make something creative and useful. With a bit of imagination, ordinary plastic caps can become colorful decorations, practical household items, fun little toys, or even products you build a small business around.
Whether you’re crafting with kids, decorating your home, or starting a small handmade business on the side, these 17 bottle cap craft ideas are simple, affordable, and enjoyable projects that are worth trying at least once.
