How to Make a Mosaic Out of Seashells

Updated February 21, 2017

Grab that jar of beach shells that's been collecting dust and use it to make a mosaic. Even if some of the shells are broken, you can still create a beautiful mosaic frame, tile or box to show off your seashore treasures. Make a mosaic using only a few items and display your stunning seashell collection for everyone that comes over to see.

Have an idea in your head of how you want the project to look before you start gluing which may alleviate mistakes. You may even want to dry-place the shells to perfect your design before gluing them down. Glue the shells to the surface of your object. Adhere them with a hot glue gun in whatever pattern or design you like. Break a few shells on purpose for a neat look. Let the glue dry overnight.

Spread white tile grout over and between the shells. The grout should fill in any gaps or openings between the shells. Let the grout dry for 20 minutes.

Sponge away excess grout and wipe the shells clean. The shells should be grout free, but the grout should remain between the shells of your project. The grout shouldn't be bumpy, but have a smooth look to it. Let the project dry completely overnight for best results.

Tip

Add small pebbles or beads to add interest to your shell mosaic.
