By using clay, you can shape them however you wish
Crafting projects are great for those parents who want to give their children a creative outlet. Why not put them to make coasters out of clay? It is an easy material to manipulate, it is non-toxic, and it does not stain. You can have some family fun with this easy DIY project.
The best part is that they can be customized with cutters of all shapes and sizes. Roll out the clay to about a half inch in thickness and cut the coasters out with a round cookie cutter or glass. Decorate them as you wish with glitter or paint while they are still wet.
