Thank you for all the nice comments! Several of you asked about the Fastpatch method. It was developed by Anita Hallock and is explained in her books: Fastpatch: A Treasury of Strip Quilt Projects; Scrap Quilts Using Fast Patch; and Fast Patch Kid's Quilts. (All are available at Amazon.) Basically you sew checkerboards, cut them apart diagonally, resew, and voila - you have a whole set of quarter square triangles completely done. So easy and fun! You can also use it to make flying geese and many other designs.
