Materials needed:
Hook: Standard dry fly hook size #10-16.
Thread: Tan UNI thread 8/0.
Wings: Natural deer body hair.
Tail: Natural deer body hair.
Body: Natural muskrat dubbing.
Hackle: Medium dun.
...and wrap a few figure eight wraps to keep the wings separated.
Wrap 3 turns up, and 3 turns down each wing. Just like you would wrap a parachute post.
Wrap your thread back, and prepare to tie in your tail.
Use loose wraps to tie in the tail. If you tighten your thread down too much, it will flare.
Once you start working your way up the hook shank, you can start using progressively tighter wraps.
Trim the butt ends.
Dub some muskrat body fur onto your thread, and build up a tapered body.
Tie in your hackle.
Always trim the fibers off the bottom. If you strip the fibers off, the hackle will rotate much easier.
Wrap your hackle forward, tie it off, and whip finish.
