Start black 8/0 thread on a standard dry fly hook and lay a base back to where the barb would be, maybe one turn further.
Wax the thread and roll on a thin noodle of light gray dubbing (rabbit or muskrat). One wrap to catch it, then pull tighter for a slim body, and wrap forward to about two-thirds of the shank, a little more at most; a wing and a bushy hackle still need the front. Back up and add a slightly thicker bump at the front of the body to prop the wing, pull off the excess, and trim any loose fibres.
Cut a section of Mottled turkey quill and fold it over as a tent, thin end forward and thicker part at the back. Lay it over the top so it straddles both sides of the hook, pinch wrap, put two wraps down, check alignment, then lock it in. Do not cut it to length yet. Trim the front butts as low as you can.
Strip a few fibres from a Brown or ginger rooster dry fly hackle and tie it in ahead of the wing, keeping back from the eye. Wind 6-10 turns, each right in front of the last, so the fibres stand straight out; lock it with thread and trim the stem.
Sweep the fibres back and pinch them while wrapping a small head, trapping as few forward-leaning fibres as possible. Whip finish with about four turns and add a drop of head cement.
Pull the wing out straight and cut it at an angle so it ends just slightly longer than the bend of the hook.
