want design wall. Have a large sheet of 2"x 8' foam insulation. Planning to put up 2 bookcases for material and they will fit in front. My walls are 4' at wall so no room there, attic. Buying another so will cover them and be able to move easily. Also cut top down a little so fits freer. Room is 12 x 20, but 4' on sides. Putting bookcases across room, inset some for storage behind, making closet for fabric.
