So were you disappointed in the quilts or lack of vendors? I guess I think of a quilt show as a show of quilts and I go planning on looking a quilts. If there are any vendors there at all, it's just an 'add-on' to the main event. If I want vendors, I go to one of the sewing expos, where, if they do have quilts or sewn items in a display, that's an add-on!
BTW, the larger quilt shows usually post a vendor list so you can see who will be there before you go to the show
