Love, love, love your fabric! I don't know what the diagonal piecing/flynn method is about--I guess I'm confused about what the purpose is. I went to your first link and started having flashbacks to my junior high algebra and geometry classes (and I'm 50-something years old). I'm going to have to do some Googling tomorrow--or better yet, come back to this feed and read all the excellent explanations that always come from the members of this board when someone has a question (hint, hint).
