Picture Corner Mounts

These are mounts for small unframed thin pins, postcards, photos or other thick media. I wanted something simple to use that didn't require nailing holes into the wall. I used simple Map Pins - they're the small round ones in the pictures. They're 5mm in diameter and they fit snugly into the holders and can be pushed in easily once the corner is in place. I used two corners, but you could use all four as well.
