I have a flannel design wall that has 8 gommets at the top (I think it is a Fons and Porter). Used the small 3M hangers whose hooks are of thin metal, not plastic to hang the design wall. The hooks not only hold up the design wall, but I can hang my rulers from them also. I do have to take the rulers down if I am working on a large quilt so I have use of the entire design wall.
