I like to cut small squares (about 4 inches) of some fabric that I don't think is good enough, or pretty enough for the top of a quilt. That is my background. I use the sew and flip method to use up my crumbs and cover them. Makes really cute doll quilts, potholders, book covers, change purses, candle mats, etc. etc. The two layers gives enough body for lots of things where you like a little extra body.
