If your goal is to win a prize, then I would find out who is judging the show, research how they have judged differnt quilt techniques in the past and make your quilt to suit them. ( I hope you can tell I'm kidding!!) Make the quilt you like to the best of your ability, enter it and learn from the experience. I have seen lots and lots of shows, and have entered several. Some shows, I can tell why the winners were chosen - others, I have no idea why the judge passed over one quilt for another. Don't worry too much about entering. If we all only entered to win a prize, there would be precious few quilts in a show for us to admire.
