The hubs and I have been pretending to be bats for the past month. Well, not really...we just didn't have any windows in the batcave our bedroom. It was great for the hubs while he was working night shift! Me, not so much! I can tell you having no windows makes it REALLY hard to wake up in the morning. Not an ounce of daylight shines through OSB!
Eventually all the plaster will be coming out of this room so we can rewire and add insulation. For now we have this beautiful "trim work" to look at!
