Perhaps your show has a 'display only' category. That way, your quilt can be in the show and not judged - just displayed. I've put several in shows - some got ribbons, some not, but I've found that even though the judges did put down what they thought were faults of your quilt (I'm betting you already know what they are), they also write down what they liked about your quilt - which is always nice to hear. It's your decision of course, but I'm willing to bet you're harder on yourself than the judges might be!
