Don't you know the "quilt police" have X-Ray eyes.
Having said that. Put another back on it. I recently saw a quilt that had a lot of decorative quilting on it - scenes etc in varrigated thread. then a backing had been added and then the background had been quilted. It didn't qualify because the rules indicated that all the quiting should have showed on the back. So read the rules. However, it is done and accepted.
