I found a package of 6 foam insulation board pieces, each 18" x 48". I duck taped 2 together on one side so they will fold. I did this with 4 pieces to make 2 separate 36" x 48" boards. Covered these with flannel. When I need the board I can lean against the wall next to each other. This works for me. I live in a condo with minimum storage. These fold up for easy storage and fit in the car if I want to transport.
