I bought the Fabric Mover when I bought my machine several years ago. It's one of my biggest regrets. The Fabric Mover - not the machine. It seemed backwards to me to be moving the base to move the machine. I guess I'm just not that coordinated. So now it sits in it's box in the closet. When I think of what I paid for it, I feel ill. They're going for about $50 on ebay now, I see.
I think the sewing machine shop was pushing these at the time. I bought into it. Can you tell I'm still unhappy about it? I could have bought a lot of fabric with the $$ I spent.
Thanks for the posting - you let me vent.
