I made 11 sets as was required for the busy bag swap which meant painting 264 little symbols. I believe this took me about 4 hours. I began by dividing 132 stones into 11 groups of 12. I was careful to choose stones that I thought looked nice together. Each stone has a symbol on either end making 24 symbols in a set; six birds, six snails, six cats and six fish. Finally, I sprayed them with a coat of clear gloss enamel. Phew, I was glad to be done.
