How to make a DIY keychain with plastic bottles?

Dec 19, 2025

Hey there, craft lovers! I'm stoked to share with you a super fun and eco - friendly DIY project: making keychains out of plastic bottles. And by the way, I'm a DIY keychain supplier, so I've got tons of cool tips and tricks up my sleeve.

Why Use Plastic Bottles?

First off, you might be wondering why plastic bottles? Well, there are so many plastic bottles just lying around, and it's a shame to waste them. By turning them into keychains, we're giving these bottles a new life. It's not only great for the environment but also a fantastic way to show off your creativity. Plus, plastic bottles are super easy to find. You can grab one from your recycling bin or even ask your friends and family to save theirs for you.

What You'll Need

Let's start by gathering all the stuff you'll need for this project. You'll obviously need a plastic bottle. Any size or shape will work, but I'd recommend using a small one, like the kind that holds water or soda. You'll also need a pair of sharp scissors or a craft knife, some sandpaper, paint (acrylic paint works great), paintbrushes, glue, a keyring, and any decorative items you want to add, like beads, sequins, or stickers.

Step 1: Preparing the Plastic Bottle

Once you've got your plastic bottle, the first thing you need to do is clean it thoroughly. Wash it with soap and water to get rid of any dirt or residue. Then, let it dry completely. After it's dry, use your scissors or craft knife to cut out the part of the bottle you want to use for your keychain. You can cut it into any shape you like, such as a heart, a star, or a circle. Just be careful when you're cutting, as the plastic can be a bit tough.

After cutting, the edges of the plastic might be rough. That's where the sandpaper comes in. Take your sandpaper and gently sand the edges of the plastic piece until they're smooth. This will not only make your keychain look nicer but also prevent it from scratching your hands or other things.

Step 2: Painting the Plastic

Now comes the fun part: painting! You can choose any color you want for your keychain. If you're feeling really creative, you can even paint a design on it. For example, you could paint a cute animal, a flower, or a pattern. Just make sure to apply the paint in thin layers and let each layer dry completely before adding the next one. This will give you a nice, even finish.

If you want to add some extra sparkle, you can mix some glitter into the paint or use glitter paint. It'll make your keychain look really eye - catching.

Step 3: Adding Decorations

Once the paint is dry, it's time to add some decorations. You can use glue to attach beads, sequins, or stickers to your keychain. You can also use markers to draw on some details. For example, if you painted a cat, you could use a black marker to draw on the eyes, nose, and whiskers.

Get as creative as you can with the decorations. You can make your keychain look as simple or as elaborate as you like. And don't be afraid to experiment with different combinations of colors and materials.

Step 4: Attaching the Keyring

The last step is to attach the keyring. Use a small hole punch or a sharp object to make a hole in the top of your keychain. Then, thread the keyring through the hole. And there you have it! Your very own DIY keychain made from a plastic bottle.
