I saw this on Charlie's site, and it looked good to me. I used peacock herl
rather than muskrat for the thorax.
Hook: Mustad 3906
Thread: black 8/0
Body: Mylar and Orange Floss (One strand of floss picked out of 3 strands)
Thorax: Peacock Herl
Hackle: Hungarian Partridge
Charlie's method for hackling these flies makes my life much easier. He snips
a V section out of the top of the feather, ties in the hackle with two loose
wraps, and then draws out the feather until the hackle length is correct.
Charlie says he can use thread torque to spin the hackle around the hook,
but I usually need to tweak a little before tightening the wraps. No more searching for little feathers!
