Plastic bottle keychains repurpose plastic bottle caps into functional and colorful accessories. It’s an easy way to craft small items out of otherwise discarded plastic.

Gather plastic bottle caps of various sizes and colors. Drill a small hole at the edge of each cap, using a nail or small drill. Attach the caps to key rings with small jump rings or metal loops. For added flair, paint or decorate the caps with markers, stickers, or glitter before assembling them.

You can also glue small charms or embellishments to the surface of the cap. These keychains are lightweight, customizable, and make for great gifts or personal accessories.
