Has anyone used this quilting frame? I need to get a hand quilting frame but not sure what to buy. I also thought about a swivel lap hoop but the ones I can find on line sit ON your lap, I wanted one that you sit on and it comes up between your thighs. I would think you'd be spending a lot of time trying to keep the one that sits on your lap from falling off and it just does not look like it would be as stable. Any advise on a frame?
