I just learned that pre-cut squares aren't always "square". Aren't they die cut? Isn't that for accuracy? I was given what I think are charm packs? 100 5" squares per pkg. and a couple jelly rolls to make a charity quilt. I was excited, no real cutting. I'm going to have to square up every block. And no, I'm not going to square up every square. I decided a 4 patch was a safe way to go-hope they look better pressed.
