I got OC 703 2". All I did was cover them with muslin. No frames. I glued a thin strip of wood to the back and hung them like pictures. The two I put on the celing I used cup hooks. In the corners I took Ethan's advice and put two together to make 4". The panels are 2'X4', so 96 sq feet is 12 panels. I know 12 may not be enough but there is a dramatic difference in the sound of my room.
