Here's another pattern from "Montana Trout Flies" by George F. Grant.
The recipe from the book
Hook: Mustad 9672, #4-6
Tying Thread: Black Nymo - Size "A"
Tail: Scarlet & Yellow Hackle Fibers
Body: Peacock Herl
Hackle: Scarlet & Yellow Saddles, Palmered
Rib: Fine Gold Wire
Wing: Gray Squirrel
Head: Peacock or Ostrich Herl, Full
The scarlet and yellow body hackles should be "doubled" or "blended" together prior to tying in by the tips at the tail end of the fly, and then wound on as a single hackle, wet-fly style, over the peacock herl body.
The process of doubling, setting, or bending a hackle, as it is variously described, is quite easily accomplished by putting a hackle plier over an upright post and then catching the the hackle tip or tips in the hackle plier jaws, which leaves both hands free. The butt end of the quill is held with the right hand and the hackle fibers are folded over from the butt to tip with the left hand.
