Mod Podge rocks
The idea behind these rocks is that you will decorate them and place them in locations for others to find as a “random act of kindness.” Isn’t it a cool idea? It’s a great summer craft for kids or adults.

Pick smooth, flat rocks. You can decorate any rock, but it's harder to decorate ones with ridges. If you can't find them in nature, the craft stores sell them as do home improvement centers.
Wash the rocks before painting them. You want to remove dirt so that it doesn't mess your design. You can wash several at once with dish soap and leave in a colander to drain and dry.
Seal the rock before painting on it. Use a clear brush on or spray sealer. This helps so that the rocks (which are porous) don't suck the life out of your markers.
