Doors Into Tables
How many hollow-core doors are in this room? 
Actually there are four. Two on the wall and the two tables in the back of the room! I'm going to refer you to one of my blogs on Active Rain: A Table for All Seasons. Since Thanksgiving is coming up many of you are trying to figure out how to set up an extra table. This is the easiest extra seating solution in the world!
Buy a hollow-core door, paint it, and set it up on two tray tables. That's it!
