The stones can be printed with words such as
If you are using poly clay roll it out to form a small round shape and then using the stamp press the word into the clay and bake it as per the directions on your clay packet.
If you are using normal air drying clay follow the same directions as above except allow it to dry in the sun for a few days before painting it with some acrylic paint.
Once both versions are hard and dry, coat them with some clear varnish for a polished look.
You can also use these stones for Zen gardens or place a few of these into your glass vase for a interesting look to your flowers.
