How to tie it
Start thread at the 70% mark, build a small thread base, and tie in an upright post of white CDC or poly yarn one shank tall.
Run thread to the bend and split a bunch of dun Microfibetts wide with a small dubbing ball, tails one and a half shanks long. Spinners have long splayed tails.
Dub a slim, tapered gray abdomen forward to the post.
Tie in a dun hackle at the base of the post.
Wind the hackle 4-5 turns parachute-style down around the post, barbs standing flat and out.
Dub a thin thorax through the post base, figure-8ing under the hackle, then secure the hackle tip.
Whip finish under the eye and cement the thread only.
