Personally, I would fix it. Though some have said they wouldn't have noticed had you not pointed it out, I saw it before I even read your post. I think your quilt is absolutely beautiful and it would be a shame not to have it exactly as you want it. (It doesn't really matter what anyone else would think of it the way it is right now though, it's how YOU feel about it that matters.) I've been there, believe me! lol I had to rip out and redo one of my quilts a couple of years ago and in the end, it was well worth the extra effort. :D
