I find that with more and more quilts you become better and better without stressing about it. I think when you are happy with the quilt and the look of it thats the issue not that it is perfect... My mother in law says the Indians say if it is perfect it lets the devil in so, a little imperfect makes it yours.... I am not perfect and will never be and the people who receive them love them just the same.... Enjoy quilting and in time your little imperfections will be come less and less ---- Sometimes I am amazed that my blocks match.... Enjoy and that is all that matters...
