I happen to be fortunate enough to have an inexpensive New Joy quilting frame and I have found that I can pin my backing to the take up rollers (pinning to the leader fabric) then I put down my batting and quilt top. Then I pin baste it while standing. When finished with that section, I remove the pins and slide the "sandwich" up and re-pin it again. I repeat this until all is basted. This is done for the smaller quilts that I quilt on my regular machine.
I have found it saves my back and legs and it's also in the same room - on the same floor! :-P
