I put these "peace" rocks out for the taking last week... Free.
My sister and I made them one day while sitting around before the election, talking about the state of the world and hoping for change.
When people came in to the studio/gallery and were interested in my pieces and the process, I offered them some peace to take home. They loved it.
We started out with 30 or so... All of the rocks are gone now.
Time to make some more peace.
