There is that... I already know about it. The other side of that is sending in the required two pictures, a full one hanging up and a close-up of the quilting. If I don't show the flaw and it is accepted and then seen in person, that seems deceptive on my part.
I couldn't with good conscience do that. Would it be any different than knowing there is a huge problem with the backing and I only present a picture of the front of a quilt for consideration?
