I've never been able to do "perfect" and it doesn't bother me at all. I had a sister-in-law who was such a perfectionist that she was never, ever satisfied. I remember not wanting to be like that. And I'm not.
I've noticed with quiltmaking that I try my best and don't like mistakes but once the quilt is finished I tend to forget about the mistake/s I made. It all seems to pass once it's washed and used. I usually forget where it was after awhile.
