I spray baste, using my bed (with an old sheet underneath to catch overspray) as the table. The only time I use the floor is when the quilt is just too big for my king sized bed and then I recruit the assistance of my DD whose knees are in better shape than mine! One time with the basting spray was all it took to convince me that I will never pin again. There is some smell, but with good ventilation I have no problems.
