My standards...??? FUN! My first priority in quilting is that I enjoy what I am doing. I use to be very picky about everything I made and would become very depressed at my results because they weren't perfect.
Then my neighbor and I started meeting once a week to work on Eleanor Burn's Undergrouond Railroad. Both of us found that we were having fun with the quilting and when the other one made a mistake, we were honest but encouraging to each other. If the mistake was too much we would tell the other one but many times, we found that our mistakes were not as big as we would personally think and we didn't need to do it over.
The funniest mistake I made was on the flying geese block. When I put the 4 smaller blocks together, I accidentally turned one of the blocks so you have the geese going around the block in three of the squares but they are flying out of the block in the 4th square. I didn't spot this until after I had trimmed up the block. I looked at it and started laughing....I said, "the geese are escaping from the block"... I didn't redo that one because every time I look at it, I start laughing.
That is when I realized that my reason for quilting was for "MY" enjoyment and I wasn't going to worry about the small stuff. I will redo some things if they are really noticeable but many times things are not as noticeable as the maker thinks.
