I made window covers from stuff I had on hand. They will prevent people from looking inside and prevent condensation. When not in use they just go under the mattress.
I cut some black foam board into the shape of the windows and covered the edges with window seal rubber tubing. Then I attached a few Naugahyde tabs on, and glued pieces of refrigerator magnets to the back of the tabs. Finally glued some button magnets to the door. The glue is not a noticeable as it appears in the photo.
