I meant something that looked nice. The hardware, surface conditioning, and paint job is not a trivial expense, after the lumber is bought, cut, and assembled.
A cheap cheap version could be made out of furnace plenum duct metal. Or cardboard. Actually I’d prefer to be rolled up in a piece of old carpet torn out during remodeling.
