I wanted to show you a few more magnetic boards. The red one above is just a simple 1 x 4 wooden frame I built with the sheet metal screwed to its back.
Remember to take a magnet along with you to check your metal before you purchase it.
The board below is a store bought frame with a piece of sheet metal cut to fit where a picture would normally go. You can get all of the details from Cheri's post HERE.
