I would not be without my design wall. Mine is 8' by 16'. I used the shiny insulated backing board (very light weight and about 3/4" thick) you can get at Home Depot for about $10 apiece. Used two pieces...covered them with batting and secured batting on back with duct tape. Placed two covered boards side by side on one wall in sewing room and secured with deck screws. Fabric sticks to batting and you can also push pins in since it is foam. My design wall is large enough for me to actually layer my quilts...my backing, batting, quilt top and spraying each layer with adhesive. No more crawling on floor to prepare quilt and no more pinning!
