I recently taught an Earth Art class at the Coastsiders Senior Center on Half Moon Bay. We had a brief talk about Andy Goldsworthy and mandala symbolisn. The elders had bunches of material to work: stones, flower petals, leaves, sticks, and more. Most of the materials were gathered during a walk and some donated by a flower shop in town.
We had an “instant art show” at the Senior luncheon for the enjoyment of the diners.
