Frieda Kipar Bay is an herbalist. She teaches workshops on growing herbs for medicine. A class like this might normally cost $50-$60, but at a recent workshop at the Homestead Skillshare Festival, at Hayes Valley Farm in San Francisco, students didn’t pay a dime.
The daylong gathering – which included 40 different workshops, food, and live entertainment – was funded with a different kind of currency: hours. These transactions are managed by the Bay Area Community Exchange Time Bank.
