At the Madison WI quilt expo, we saw "The Weightless Quilter". It is a floor frame engineered to support the weight of a quilt. It was meant for machine quilting, but I don't see why it wouldn't work for hand quilt. It hold the quilt up and away and our of your way as you work on a section. It ONLY costs about $250.

Sorry, the weightless quilter is not at that site. Maybe you could contact her if you are interested. I think she invented it, and that may have happened recently.
I have seen others hang their quilt from the ceiling with elastic bands.
