I have seen something similar, but it was held in place by a wood frame sitting on the table. The people from whom I bought my HQ16 made one for the Sweet16. Not so sure I would ever want my ceiling messed up. I alswo move my sewing cabinet to different places depending on what all I am doing.
I just use extra tables in front of my machine, and beside it if needed,so the quilt bv stays at machine level without any drag. Bougth the Lifetime tables that are easy to store and put up.
