ghostrider, thanks for clearing that up. It makes sense that your personal label should be anything you want it to be and wherever you want it to be, but for entry in a show, a special entry label with perhaps more information (so you hopefully get your quilt back) would be expected to be attached and in a consistent place. If I was entering a contest (never have so far), then I would try to find out everything I could before I got there ready to show.
I'm sorry ladies, but the comments about not following any rules sounds like petulant teenagers. You don't have to give up your creativity to cooperate with the requirements of a given show.
