I pin the sandwich before quilting and then take the iron to it. If it's a large quilt, I sometimes use 505 spray on it to help hold in place as well. I would pull the table away from the wall and maybe put a card table behind your sewing table. When I'm doing a queen sized quilt, I'll put a chair to my left to help hold up the quilt on that side. Of course, the cats usually think that chair is there for their convenience
