This is the door I'm covering. I'm making this part of the basement into a personal office, that is in continuity with the darkroom. Thus the need for a blackout shade for the door. My desk will be right by the door, so I want to still be able to look outside and use the door when I'm not printing or loading film-holders. I did not put drywall in the darkroom, because I didn't want to cover any of the wiring and plumbing, in case I need to modify or service anything.
