[}]...Oh, I forgot to mention! To make alcoves, or "rooms" which would hold your scenes, just turn the direction of your plastic. If you're doing this in a school it will be really easy. The drop ceiling tiles can be pushed up and out of their squares, and then you can tie off in any direction. I have two 100' sheets (one on each side of the hallway) and have never had to cut any plastic to make rooms. This is best done in a large room with a lot of negative space that you won't use (such as an empty class room), whereas you can make the actual walkway about 5-6' wide, then make the scene areas push out to whatever size you want, then bring the plastic back in to form the hallway again. If you were to hang the plastic AROUND the room, you would have no partioning. Instead think of an overhead view of a maze that mice run though, these sort of shapes will help you out...
