This is the pattern I have for the Picasse. As Bill stated the one he got from Mark is different. Mark is not a static tier. His flies seem to evolve depending on needs and materials. If you do a search on "Picasse" also as Bill stated, you will find a few threads that have great info on the fly.
Body – V-rib or any similar body material. Either black or clear over black thread.
Wing – Black over yellow bucktail.
Hackle – Blue Eared Pheasant
Sides – Lady Amherst Pheasant and Jungle cock.
