I use two identical ironing boards, raised to the same height. Then, I put two 3 x 6' pieces of plywood on them. Cover the plywood with contact paper and then spread out your quilt and clamp it to the sides all around. You will have to move the quilt as it probably won't all fit onto the basting surface at once. Start in the middle and work around. You can also walk around it which helps. Yes, it is a pain to put up and take down, but it's better than not being able to get up off the floor.
