I agree with the other posters, if it bugs you, you'll probably be happiest if you fixed it. I find that i am not as festidious on baby quilts and will leave something if it's within an eighth inch because they probably aren't going to notice and once it is washed most naked eyes wouldn't see it. But on any other project, if I catch something that's not right, I will fix it and chalk it off as a learning experience.
