I just had to pin my king size bow tie quilt. I can get a full and queen on the floor in the livingroom, but not the king, but...I found the trick. I lay the backing on my king size bed, then add the batting and top. I can keep it straight and pin it standing at the end of the bed (roll it up as I pin it, and pull it down towards me to continue). Works GREAT. No more getting on the floor for me.
