A San Franciscan looking for, say, a gun necklace to accompany their VP candidate Halloween costume will be happy to know they can find one that was created without leaving a trace. The Appel & Frank Eco-Chic shopping event on Thursday evening at the Regency Center on Sutter combines sustainable apparel, jewelry and personal care products. I had a blast last year and am looking forward to organic and recycled jacket designer JulesElin and free wine from 7 Daughters. A portion of the proceeds go to Friends of the Urban Forest’s efforts to plant and care for groups of trees in city neighborhoods.
