I think this is the old lemons into lemonade. I have a large stash and it is great to pull the back from what I already have on hand. I try to make the colors on the back harmonize with those on the front but otherwise I design a simpler pattern on the back. Recently I made a postage stamp scrap quilt with the middle panel on the back the same size squares but only two different fabrics. Won't do that again, really difficult to get the back lined up to the front. Love everyones backs!
