I tried something similar when I lived in a small condo. I suspended a board (1" x 2" x 8' long) with heavy string and plant hooks that screw into the ceiling. Using large hinged paper clips, I attached all three layers to the board.
First thought was "Hey, this might work!" I then tried to pin the layers together. Between the swaying of the board and trying to reach behind the quilt, especially in the middle, to steady it and provide resistance as the pin point came through, I gave up.
Sounds like a good idea but.... I ended up using the set-up to hang fabric as a I ironed it. Worked great for that!
