I could not tell you the exact recipe for the Thin Mint eventhough I have looked at that damn fly in the boxes at work over and over and over again.

It is a pattern, developed by George Cook of Sage, Simms, Issacs Ranch etc. fame and has a tail of brown and olive marabou and a couple strands of small pearl flashabou. It also has a gold bead head and I believe a body of olive dubbing and brown hackle or vice versa. Just remember to keep the dressing the light...
