Okay, so I started blocking in the walls for the attic set. All four walls need to be removable from the floor and each other, so I can put the camera anyplace I need to. I'm going to use dowels and a little velcro to hold the walls in place. I'm using 1/2" foam board for the triangle walls, and 1/4" for the sloped walls. Using plywood or pressboard would've been just too heavy. The walls and floor will be planked with balsa wood, then scenic treated to give it the proper aging. I need to buld the doorjamb, door and the window treatments as well. I'm hoping to get the fourth wall cut out today.
