I have the Little Gracie II. The pantos sit under the machine on the shelf with no space lost in the room. My sister has a Grace GQM, and the panto shelf is attached behind the frame and a lot of space is lost in the room. - I still need to be behind the machine to quilt when doing pantos, but only need about an extra foot, just enough room for me. The frame already has to be out far enough that the machine does not hit the wall. The Gracie II frame also fits up to a 16" throat and a queen size quilt. -- My room is only 15' X 8'. I built a base for the frame to slide it back and forth when using it.
