I was given a box of 6x6 tiles and some plaster earlier this year. I thought that would be the perfect start for this project. We mixed the plaster with water and a little school glue but it hardened up way to fast. So on to plan 2, just use the glue.
First the participants drew their designs with pencil onto the tiles. Next they started filling areas with glue then adding the colored stones. They did need to be reminded that it was essential to use enough glue to hold the stones--Do Not Stint on the glue. Everyone seemed to have good time and turned out some great designs.
