Crafts with bottle corks

You could connect them side to side to make a design like a heart or a letter of your last name initial or a star, connect (glue)them to an old barn wood or pallet board (or 2) and make a message board where you can pin messages, attach them to the bottom of pinecones and paint the pinecones to resemble trees, glue them end to end in rows to cover a cheese cloth or burlap to make a mat for the counter are a few ideas that come to mind. Also various small shapes for ornaments on the tree (with pipe cleaner you could make reindeer)

This link from Pinterest has tons of ideas:

When we renovated the kitchen in our house, I had my own desk, finally! I painted the wall behind the desk in tan, & hotglued corks, halved length-wise, to the wall. I now have a huge "cork board" to post whatever I want.

Cool idea!
