Thank you to everyone who left comments on my previous post. I really appreciate the insight.....I think I now know what a 'flange' is, its the border width, which I never noticed was uneven....as the judge sheet stated it is.
Taking out the quilt, I still couldnt see any uneveness with my eye, but I measured it....and there is a minor difference! My eyes are opened!
I've included a shot above of the border edge, where the flange is....I'm assuming its the edge sliver of gold trim just before the binding. So there you go, you learn something new every day.
