It was about a dozen years ago that Ralph Hoffman demonstrated his method of tying his signature fly, the Black Turkey, at a meeting of the Catskill Fly Tyer's Guild. This was a wet fly that had a simple recipe of peacock body, brown hackle and a turkey tail wing. Ralph used the folding method described in the initial post and used by Andrew Davies. Also, when necessary, Ralph would trim the ends of the folded turkey tail to shape it slightly.
