I was at the Quilting and Craft Show in Brisbane on Wednesday, and there was a new sort of quilting frame at one of the stands. It was vertical! Would be OK for basting, but for the life of me I can't see how you could quilt on it. Save your knees and back though, but at $420 I'm not about to try it.
Every time I went to check it out, there were so many people around it that you couldn't hear what was being said.
The only link I can find for it is
It appears to be all made from square metal tubing.
I'm going to use the tables at the local library in a couple of weeks. They were very happy to let me when I asked them today.
