If you are going to mount it above your sewing machine, the bottom can rest on your desk to relieve some of the weight if you are worried about the command strips not holding it up. Don't forget the other surfaces in the room. Perhaps you can mount it to the back of a wooden door? Maybe to the side of a wooden fabric shelf? Peg board is super for all your hanging notions. Someone on this board mounted hers to the back of a wooden desk.
