Ah, deep obsessive hobbies. My mother once made a couple of suits for herself and my sister-in-law, starting from an almost raw fleece (she refused to do the cleaning of the fleece to get rid of the twigs and other crap). Also, for clothes construction and fabric arts, see my sister-in-laws blog, which made the front page of HN a few months ago. [0][1] She makes clothes, and teaches the art and craft of it.
