Miters are my downfall. I've been quilting for years and even though I've been shown (in person), read how and seen videos how to do mitered corners, my "intelligence" flees when I try to do them. Give me a block with a zillion points, no problem. Give me four corners or a border to miter, forget about it! Grrr...and no, it's not Murphy's Law, it's actually Boyle's corollary to Murphy's Law: "Murphy was an optimist". LOL
