I started buying Men's cotton shirts 15 for $3 at a thrift store. My first quilts were all from men's shrts. Still using that stash and now the shirts are 15@$5 still a lot of material for little money. buy remnants at JoAnns occasionally yardage for a specific project. Did calculate what one quilt cost and I was shocked! All new fabric. I use old sheets for backing either from thrift store or some I inherited when a friend passed.
