Really pretty pottery, handmade. I love this kind of place: a little artists' studio stuck off in the warehouse district of Berkeley, with just Bayer and some nurseries to keep it company. And it's a co-op! actually, there are a lot of hidden art gems in this neighborhood, but few with the visibility that Earthworks has. Plus it puts a shelf of used books out for sale - whether as a side project or to attract attention I don't know.
