My goodness, do you ever sleep? You must be the world's most organized woman. I'm afraid to say, no matter how you try, you will never be able to use up all your fabric on a project. There will always be some pieces left. If you must have a project for them, I suggest you start a collection of 4 or 9 patches, pinwheels, friendship stars, or some other simple blocks and keep them together. When you have enough, make a lap quilt to have on hand when needed.
