Mistakes are much more easily seen in a picture or through the camera lens.
I made a quilt at least 10 years ago of squares, every other one tipped to the right or to the left. That quilt had been in at least four quilt shows/displays and had been on my bed for two years before I noticed that one square was tipped the wrong way. If I had seen that when it was still a flimsy, I might have changed it, but it really didn't matter, did it. I still love it.
