I bundle up the fabrics that are purchased specifically for a certain quilt-I may or may not have every fabric that I need. I have found that if I don't keep them together, I will either forget that I only bought a half yard of this to go with that quilt, or have used some for something else. I then tie them up with a long selvege and stack them on my shelf. I will put yardage, FQ, 1/2yrd Pieces-whatever I purchased for that specific project. If I have started that project, but had to put it aside for some reason, then it goes together in a project bag. After I finish the quilts that I'm making for gifts for this year, I am organizing my room, stash and finishing my UFO's?
