Hi Andy

Try using masonite for those skins and stuffing shredded newspaper between them. You could probably use cardboard if the structure is inside the barn/garage... Use 1" x 2" strips to seperate the surfaces. Make one side masonite and the other cardboard to keep it solid but also keep the cost down. You could make several 4 x 8 panels, connect them with plummers tape/screws and possibly just toss a good heavy tarp over the top. Totally break-down and stack in a corner when not in use. Clear plastic top and flaps for the doorway will allow light in. Just an Idea...
