I think you need to get all of your quilting "stuff" in one place and then you can make some decisions. There is no law that says you must finish everything that you ever started. It really is ok to re-purpose, down size, change or gasp give away things that no longer bring you joy. Sometimes projects seemed like a good idea at the time but now you just have no interest in ever finishing them and do not want to invest any more money or time on them. Gently say good-bye and bundle them up with any remaining fabric and the instructions and give them to your local quilting group and I'm sure someone will finish them and find a home for your "outgrown" treasures.
