I do the best I can, will fix what I think I can. There are some types of matches that I really struggle with, and will let some of that go as I know that I'm my own worst critic and no one else will ever notice a mismatch. I've also been working my way through a precision piecing book, and for those blocks, I will redo until it is as perfect as I can make it - I will work on that when I am in the mood for all of that pickiness. Most day to day points that aren't quite pointy, or seams that don't quite match - are pretty hard to spot when the quilt is finished.
