LOL, I've written and deleted at least 10,000 words trying to answer this.
At this point in my quilting career I'm satisfied with most of my abilities and the biggest criteria I have for how well did I do, is how closely does the physical object match my mental vision.
Providing that it is well constructed and can hold up to the wash, my workmanship doesn't have to be perfect -- but it will look just fine, might not win any awards going over it with a magnifying glass but that's not what I'm trying to do. If I'm trying to make an award winner, well yeah, that takes a lot and I think I can... but I just don't want to.
