If you've ever done a rag quilt (or are going to) - definitely get the rag block dies. I will NEVER EVER make a rag quilt again without die cutting the raggy edges! I did one about 3 years ago and I don't think I've recovered from it yet!
I also recommend doing test-cuts on plain paper with your new dies and measuring the resulting pieces to be sure they're all accurate,
before you cut any fabric. I've only ever gotten
one die that was off, but I didn't notice until I'd cut a TON of squares that were all 1/8" too long in one direction!
I hope you love it!
