I usually tie these with brown, black or olive thread, also with badger, cree or grizzle hackles.
Works well on stillwaters and rivers.
Hook: Curved, this is Mustad C49S #16

Hackle of choice, around 2x gape width, you can go longer if you feel the need.
Thorax: Hare's ear, you can omit this or use dubbing of choice.
Start thread and wrap down to how long you want the body, spin thread to cord it (usually clockwise) and wrap back up in open turns to rib.
Make a dubbing loop and hang off parachute gallows, this is over my bobbin holder.
Tie in hackle.
Leaving thread at eye dub lightly, wind to back of dubbing loop and back to just before eye.
Wrap hackle around loop and tie off.
Take loop off holder and tie in with a couple of pinch and loops. Apply varnish/super glue to tie off point now, the durability of this fly depends on how long that tag end stays put.
Pull tag to raise hackle into position, cut off tag end, add a drop more varnish and whip finish.
Gink the hackle and it sits like a good un.
