Jenne P, who pens the blog lixo-lux, recently wrote a post on a class she took with Tomoko Torimaru back in 2006 at the de Young. I found the post only because she pinged back to yoshikowada.com (which I manage alongside this one and a few others. Aah, the connectedness of the internetz!)
Her post, "Almost impossible, yet possible," is replete with beautiful close-up pictures of Miao embroidery -- so go check it out. It was great to read her side of the class experience.
