Materials needed: One custom cut piece of sheet metal, nails, hammer, cardboard, lots of alphabet letters!
Step 1: Make Holes. Lay the sheet metal over the cardboard. Take a nail and hammer it into the sheet metal until a hole is created. Repeat on the corners and every few feet along the edges.
Step 2: Have someone hold the sheet metal up to the wall and starting at the bottom put a nail into the hole until it is flush against the wall. Move upwards making sure there are no gaps or holes between the wall and the sheet metal.
Step 3: Add the letters to create a giant magnetic alphabet wall.
