I found this video today that explains how to make your own air dry clay. It looked easy enough so I thought I would try it.
I followed Chelly's recipe for a double batch. I also added about 1/2 teaspoon of one of my coffee shop paint colors and 1/4 cup of beach sand. Real beach sand. :D
The clay is soft and fun to work with. After I kneaded it for a while, I rolled it out between two pieces of waxed paper. Then I cut my "stones." I need to work on getting them the right shape and size.
Now I'll wait for them to dry. Then I will glue them on wood to see how they look. If this works it will be really easy to add stone to the exterior of the coffee shop. Easy and practically free! Love that.
Right now I'm going over to my neighbor's garage sale. I'm sad to see him move, but I can't pass up the chance to see what he might be selling!?
Later thoughts. My stones are almost dry but are very fragile. I tried sealing a few with matt ModPodge. That helped some. I'm going to try another recipe too. You can find it here.
