Some ways to use leftover wine corks include making craft items such wreaths and corkboards, or cutting them into smaller pieces for a placemat. Wine cork is versatile, easy to work with, and is usable in its natural state for most projects.
If you want to be a little more crafty or creative, it is possible to create a jewelry organizer that makes use of corks. Depending on your needs, either retain their original size or trim them a few inches. Secure a few of the corks to a board and use them as handles for hanging necklaces, bracelets and other items.
