I have 2 different floor hoops from Hinterberg - an 18" and a 29". I bought the the larger one first and someone said it was easier to use a smaller hoop so I decided to get it. Either one works well. They till easily and out of the way - it keeps the quilt up and off of me. I also have a frame that looks a bit like a card table with the quilt in it - it folds up and fits under the bed but the "hoop" is square and the corners are connected with brackets and screws. (I bought it about 25 years ago at a quilt show.) It holds the quilt fine, but it doesn't get out of the way very well, and I have to sit up to it instead of pulling it up to me.
