I'd sure hate for you to be disappointed with a beautiful blocks that don't match up.
Well, you have a good point there. It's probably not a good idea on a mystery quilt since one doesn't know what size blocks are coming up. She might call for nearly any size, and if a person isn't comfortable doing the math it would be better to remake them. Bummer!
