Steps: 1. Either purchase or cut a 24-inch round 3/4-inch thick piece of plywood or pressboard with a jigsaw. Spray paint the bottom and sides to protect the surface and for a clean finish (figure A). Let dry.
2. Break up the mosaic tiles with a hammer for the background pieces. Place the tiles on a towel on a hard surface. Cover the tile with part of the towel and break tiles into smaller pieces with a hammer. Wear saftey glasses to protect the eyes.
3. Lay out the mosaic garden tiles on the 24-inch round. Try different designs, colors, arrangements, until a preferred design is created. Place marbles in the center of the piece.
4. Glue down the mosaic tiles by beginning with the larger three-dimensional tile pieces. Apply the adhesive on the back of the tiles with a butter knife (figure B) and then place the tile in the desired position. Lightly press down on the tile to make sure it is set (figure C). Remove any extra adhesive with a paper towel.
5. After the larger mosaic pieces are set, work from the center and set the small broken tile pieces (figure D). Let set for at least 24 hours before grouting.
6. Add a signature by placing initials/name in a special place (figure E).
7. Mix the powdered, sanded grout in a bucket with water, making sure the consistency is that of moist cake batter. Let it set for approximately 10 minutes.
