[so cheap, so easy]: Oversized Magnet Board

I've had a couple of requests for the deets on my magnet board, so...a year later, here they are. I bought sheet metal measuring 5 feet by 4 feet from a heating and air-conditioning shop. It was right around $40. We (that usually means Jeremy hung it up, and I watched) used 18 screws and 18 washers to attach the metal to the wall. We used so many fasteners just to keep the sheet metal as flat as possible.  Stella is pretty much the boss of this board, and I love that it's a place where we can display all of her works of art.
