I have the Sapphire 870 and watched & used the fab-u-motion in the shop.... but everytime I tried to figure it out in my mind... I kept coming back to that little opening about 5 x 7 " that you could stitch & then have to stop & reposition your hands.... I guess if someone gave it to me... I would invest some time in trying to learn it but I sure wasn't interested in spending big $$ in something that wouldn't work for something larger than a wall hanging in my opinion.
