There is a tutorial on this site called Rocky Road to Kansas which uses the smallest of scraps. I had never done this type of patchwork before but now I am hooked. I have just made a holdall for a friend out of scraps, where the pattern said "cut 2 pieces of fabric 18" x 20" and 2 pieces 10" x 10" I just joined scraps and then cut out these sizes. It turned out fabulous! Happy scrapping!
