I made a quilt once and the night before I was supposed to take it to the quilters I laid it out and what was the first thing I saw? A block that had a section turned the wrong way. Well, I ended up tossing and turning and finally got up at four in the morning and took just that section out and turned it the right way. Ended up being one of my favorite quilts - instead of the one that upset me every time I looked at it. I agree with most of the others - I'd rip it out and turn it. You won't regret it.
