Yes, just yesterday I made a purse and after it was completed realized the handle was twisted!! Yikes!!!
I made a mistake very similar to yours. The quilt I was working on didn't have a recipient, and it was made entirely of scraps. So, I was very lazy, I zig zagged over the error, and announced that it was staying at our house forever!
I honestly love seeing people's mistakes as much as i love seeing perfectly gorgeous finished items. It just makes me realize that we all do it and there's lots of comfort in that :)
Oh, I've done that a few times and it's the worst! Hope you were able to fix it easily.
