If you find some of the blocks are not square or are too uneven to use, sew them together all wonky and then randomly cut up to use as "pieced" post cards. Fuse to heavier fusible (Fast2Fuse or Timtex), stamp (Happy Birthday-or whatever) and send. They look great. It is a great way to use the traded blocks that are not the right size. Enjoy
