I have a large design wall that my husband made me in the basement and I can hang a king size quilt up with only about 12 inches laying on the floor. I pin the backing at the top on the wall and spray with basting spray. Then I put my batting on top of that and spray again. I then put my top on the batting and my sandwiching is almost done. I take it off the wall, lay it on the floor and finish the last little bit. I have a tack gun which I use in just a few places ( my little bit of insurance) and around the outside edge, here and there, and I am ready to quilt. I saw this on utube and decided to try it. I wouldn't do it any other way again. I have done 3 quilts this way and absolutely love it. My friend helped me and it took about 10 minutes to do the king size quilt.
