I use display boards....don't think you have to worry about it catching on fire...as long as you vent etc.I am looking for cheap ideas for a cab. I was thinking Of using card board but I amwondering about the fire hazard.
word. I picked up an enclosed entertainment center for the salvation army for twenty bucks.i always say check out resale shops for furniture always easier to mylar the walls and seal it with some caulk
Build the frame with some 2x1 wood and cover with mylar or black and white.
