In Houston, they were grouped together and apparently judged as a group as they were eligible for the award given by Ricky and his Quilt Art Center. I think they are a special category if the primary focus is the painting. However, some of the quilts that were exhibited in this category had wonderful quilting and some of them had piecing as part of the design. It is becoming harder and harder to establish hard and fast rules for a category because of all the innovation that quilters are doing. As I walked around the Quilt Fest exhibits, I often asked myself which category I would enter some of my quilts in (if I were ever brave enough to submit one) and I found it difficult to decide. Much of what I do falls in the art quilt genre but some is whimsical, some utilizes traditional techniques with a twist, lots are convergences or chantelles which are improvisational piecing. If I can't figure out where I think I would fit, how could the judges.
So for now, I will enjoy (or not) the quilts that are exhibited in Houston (or any other quilt show) and leave the tough decisions about what constitutes what kind of quilt to the experts.
