Fabric Scraps

I've been doing a really good job of starting projects this weekend but not such a good job of finishing. While starting one of these projects, I needed to find the remnants of a particular fabric.
It wasn't easy to find in this mess but I finally did find the fabric I was looking for. In the process, I got kind of freaked out about all of these scraps I've been hanging on to for years. They take up so much room and I probably wouldn't miss them if I got rid of them. But maybe I would... What do you do with your fabric scraps?
