At first I was doing all my sandwiching on the floor, then Santa brought dh a pool table, with a ping pong table that just lays on top...that ping pong table has been a life saver, lol...starting to have back trouble and it has really made a difference...i use tape and lay the backing down,smooth, tap... then my batting smoothing, then add the top..when all is smooth I just spray and do it section at a time. Have done lap to king quilts this way and no problems..
