Cut the tops of from the corks. You can save the rest of the corks to make more earrings.
Push the eye pin trough the side. Use glue to make it hold it's place. If the pin is too long, you can cut the rest of it.
Add the stickers of your choice. Attach them with glue. I used small "diamond hearts".
Add earring hooks and there you have unique earrings!;)
