I have yet to do a perfect quilt either...depending on my mood...I either accept it or rip it. I must confess I do very little ripping...lol....I also believe in the theory done is better than perfect. With all it's mistakes my quilt keeps a loved one warm and most of them don't sew so they don't even notice the errors. I believe in striving for excellence but never get bogged down in perfection...do your best whatever that is should be good enough.
