You will need:
- A map, or maps, of your choosing
- Paper trimmer
- Foam brush
- Mod Podge
- Adhesive felt
Select the parts of the map you want to display, then cut them out to a size that fits your coaster. Some people like to fill the tile to the edges with the picture they’re applying. You might consider leaving a border of bare tile around the picture for a chic effect.
Using your foam brush, apply the Mod Podge to the back of your picture and let it dry. This will help prevent air bubbles from getting trapped between the map and the tiles in the future. Layer the tile with Mod Podge and center the map on the tile. Spread Mod Podge generously over the face of the map. Apply three layers.
If at any point in the process, you notice an air bubble trapped under the map, “push” the bubble out with your fingers.
To protect your furniture, add adhesive felt to the bottoms of the tiles.
Leave the coasters undisturbed for two to three solid days. Finally, the payoff. Have some friends over and brew up some conversation with your coffee.
Some tips: I strongly recommend using antique-looking maps. These look phenomenal with a border of bare tile showing around them.
