How often do you take that final look at your quilt from the back of a galloping horse??? Why is that even said?
It's kind of like saying, "I don't care how crappy your quilt turned out, so you shouldn't either".
When you ask for advice about a mistake
you are already aware of, you are asking of people who have all different standards of what is acceptable and good. Theirs may not be the same as yours. If you see a mistake and can fix it, then why not fix it?
That being said, I recently didn't see a mistake (two pieces turned) in my Rest and Refreshing Civil War block until I posted it to the group. Then, in the photo, I saw it. At first I said I'd fix it... but then decided to leave it as a humility block. Sometimes we do need this to remind ourselves to remain humble! But even at that, it was my purpose and choice to leave it that way and not an oversight.
