We have a weekend house in the woods. It has a greatroom with a spectacular view of a waterfall. The wall facing the view has plate glass windows and a sliding glass door. I would like to be able to cover the windows at night to make the room, which has a cathedral ceiling, feel cosier, but I don't want them covered at all during the day. So I am thinking blinds. Do they make blinds for huge windows? What about sliding glass doors?

Thanks!
