I have one of the Barnett hoops, well, actually two: a 14" and a border frame. I use them on both my tilt and spin and sit on bases. I just got the sit on base and LOVE IT! Not only does it hold the hoop off your lap, it too spins and can be tilted up and down for the best position. I can quilt for longer periods without suffering the back pain and sore elbow. I have put away my other hoops.
Thanks Harry!
