Last time I spray basted, I used a wall. It started with a plastic back flannel tablecloth. Then each layer is pinned and sprayed. It is the best, best way I have ever found to baste a quilt. My new sewing room will have a blank wall just for this purpose. I just finished basting a lap quilt but I used Elmer's school glue and a table. We just moved and we no longer have a blank wall space. Anyone else use a wall to baste a quilt?
