sadly when one enters a piece into a Show to be judged/juried, they are entering the "quilt police" professionalism zone..and those who judge/jury do follow the rules & definitions set in place!
If one does not want to play by the rules, then one must keep their treasures to themselves!
A Cathedral window also is not "quilted"...other than the tacking down at intersections, so no it really is not a quilt, but a coverlet..same as the yo-yo quilts!
They are unto themselves a great work of dedication that is for sure!
