DIY: Cheap & Easy Oversized Magnetic Frame from Sheet Metal

This project might be my proudest DIY moment ever! I made this custom frame measuring nearly four feet tall (3'x4' to be exact) and it cost me $0 in supplies. It would be a fantastic backdrop for any type of print -- family portrait, maybe? colorful art project? -- and it's absolutely perfect for my black and white engineer print of an incredibly special travel photo of mine.
