In my opinion, your quilt is absolutely beautiful. I don't see any mistakes, I see the blood, the sweat and the tears that went into every loving stitch. If boo boos weren't meant to be made we would all be perfect in our craft. I for one never try to be perfect as that would make me insane and I would never get anything done. Unless you mention it no one will notice, and if they do just say it was a design element to make it imperfect.
