The only thing you'll need to buy to make this project is the piece of 3' x 4' sheet of galvanized steel, which the Jo's at Photojojo found at Home Depot for 14 bucks. You probably already have on hand the rest of the supplies, which include the following:
- Drill and 1/4" or smaller bit
- Piece of scrap wood
- Small nails or screws
- Assorted magnets
- Your favorite photos
Follow this jump to see the entire how-to. Also, the Jo's also remind us to be careful when handling the sheet of steel: it has especially sharp corners! For a somewhat similar project, check out this old how-to.
