I sort them by size and then I separate them by light and dark. when I have a lot, I make a quilt! I have made a lot of 2 1/2" strips from left over fabrics and they become donation quilts. I managed to put 23 quilt tops together for a quilt group last year for donation to a woman's shelter. I agree with SewingSuz...I get tired of seeing some fabrics even though I basically make scrappy quilts and that fabric just has to go. Lol
