I don't know the answer to your question, but your quilt is just beautiful!!! It certainly looks like a winner to me.
(Well, I do know that you need to read the different categories in the quilt show you are entering. For example, our guild really changed the categories this year. Every quilter who enters needs to read them carefully so they know which is the best category to enter. I, personally, am delighted because my quilts which are machined by me on my domestic machine won't be competing with quilts that are quilted by long arm professionals.)
