I've been quilting since 1992 and just now started squaring up my blocks and oh, what a difference it makes. If I don't read about it or someone doesn't tell me about it, then I don't know these things. Someone recently told me to square up each block. Wish I knew that a long time ago. At least I know it now. I've been reading the tips pages and have learned quite a bit. I've taken classes but no one said to square up the block. I'm learning a lot here on QB.
