In light of the critique, were there other Art quilts that yours actually competed against?
I ask because some small quilt shows don't get enough of some kinds so they are thrown with others.
One show had all art quilts in one catagory. You might think that is fair until I tell you that it did not matter what size it was. A small wall hanging isn't going to over take a queen sized quilt, unless the bigger one is hideous.
Thinking of this, and your critque on binding, you will see perspective of how your quilt was judged. It might still be disappointing to you, but think of ways to improve on your binding and you will see a change in the judging.
Good Luck! And I agree with another, if your avatar is any idea of how you quilt, you make beautiful quilts. :thumbup:
