we all quilt to the best of our abilities, but I can see getting lax on seams matching, points cut off, etc could make some get sloppy. My seams Must match, my points cannot be cut off and I will rip until they do. If it doesn't bother you, don't undo it, if it does, definetely do. I figure this work will speak of me when I'm gone. I want people to think I really cared enough to do my best, for everything. I can't defend my work when I'm gone so it must speak for me. I have improved over the years and I believe it's because I was hard on myself and made myself do it right. If I allowed too many mistakes, those mistakes just continue.
