I only make small quilts, and only hand quilt about half of those, but when I hand quilt I don't use a hoop, mostly. I have a pvc hoop, and I've used it a couple of times, but I found it awkward. I've wondered if one of those lap hoops that is supported by a piece you sit on would work better, but I'd rather buy fabric than a hoop that might not work!
I think that I would like a Hinterberg or similar frame, but again, I'm not willing to spend money on an experiment.
P.S. I use 505 spray basting on everything, and I love it. But I love the idea of paying a longarmer to baste a large quilt. I think I'll try that the next time I make a big one!
