I also try to make perfect points, seams, etc. but I will only unsew 4 times and then if it still doesn't look right, well then that is the way it is suppose to be. I feel that each time I do this I am learning something & teaching myself at the same time. If I don't tell anyone they won't see my small errors. I had to teach myself to not be in a hurry & it will get done when it gets done.
