I try to finish each project before I move on to the next. I don't have a lot of storage for WIP's. However, that being said, I do keep a box of sampler blocks that I play with when I'm between projects or when I just need a break from a current project. When I get enough blocks, I make a quilt. I also participate in a BOM club at my LQS. So I have a little variety in my life.
