Bottle-Cap Magnets and Thumbtacks
A homey take on the traditional locket, bottle caps inset with small black-and-white pictures can be used as thumbtacks or magnets.
Clear resin is poured into the caps to seal the photos and give them an appealing glossy finish.
Twist-off caps are better than conventional ones because they don't bend when removed. For appropriately small images, try cutting details from large photos or resize pictures to fit your bottle cap.
