I'm glad I read this thread. I thought it was just me. I don't do swap anymore because I don't have the tolerance for close enough. If I need 12.5" then that's what I do. If it take a try or 2 then so be it. I was afraid I was being inlisted in the Quilt Police. I don't mean to judge others so if close enough is ok for them, it's their quilt.
