My fabrics are sorted by color in bins. Fat quarters are in separate flat bins. I keep Christmas fabrics in another bin and baby fabric is also segregated. My stash is way to large but I love it. Wide backing fabric is kept together but I sometimes use regular fabric as backing and always use any large pieces of leftovers from the top on the backs. I have a large tub of small scraps and I make strips and turn them into donation quilts. I occasionally get rid of fabric I don't really think I will use and I donate that to a church group.
