The reason I was thinking shower curtains was because the room is not sectioned off at all (an attic). I was going to section off like a 4x4 section and hang the curtains from the rafters...I guess I could get some 2x4's or something but that would be alot of time and work...idk. I hear alot of people talk about emergency blankets, I dont really know what they are tho, would those work?>
