I am fortunate enough to have a room in the basement where I have 4 boards and clamps. Clamp it together and put it on four legs and stretch the bottom,batting, and top on and start quilting. I can't get down on the floor so this is the best way for me and how I learned from my mother. Never have any problems with it not being flat, it is always smooth and use a chair with rollers so I can shift any which way I need to .
