Hello Mary, Why couldn't you base using the same method my grandmother did in tack yarning a quilt. Use two by two's (4) and (4) clamps. (4) chairs EVEN folding chairs. Place towels over chair backs. then two by two's and clamp all 4 ends. Come back with quilt back, TACK, lay batting then quilt top. Bottom is taunt. Instead of yarning quilt pin it or base it, ROLL as you go. LEAVE tacks in all the way around till finished. gets you off the floor. :)
