My takeoff on a classic wet fly, the Grey Ghost, with same proportions and some of the same ingredients. I named it for the Cedar River and the olive color. My tying skills still have a way to go, but I had fun tying up a few of these.
Body: light olive 6/0 thread, peacock sparkle thread, silver flat tinsel
Throat: flashabou and cat guard hairs (free and endlessly renewable)
Wing: gray saddle hackle, peacock herl, mallard flank
Head coating is Loon Soft Head instead of the harder epoxy coatings.
