I use spray basting now, and sometimes I am not able to baste on the dining room table or the floor, so the last time I did it I used my bed. The bed is king size, I took off the bedding, put on an old sheet, smoothed everything the best I could and spray basted the quilt on the bed. I worked out very well and basted very quickly. And on the plus size I did not get a sore back.
