I have a large peice of plywood on my 6 ft banquet table. I use binding clips to hold the backing and also use spray basting instead of pins. Also I start my sandwiching on a side edge instead of the middle. That way I only usually have to move it 1 time. You just have to make sure that there is enough backing for the quilt. I can not see how you van get all the layers smooth if hanging on a wall.
