Thread -Flat Waxed Nylon

Tail - 4-6 Wide Hackles add 10-20  Strands Krystal Flash or Flashabou

Instructions:

Start thread at bend, tie in hackles splayed inward even number  per side of hook shank. Tie in flash materials on top and sides of hackle tail. Choose the largest webbiest hackle bases in the strung hackle, tie in and wrap thread forward and palmer hackle forward tightly. Trap the hackle with thread when you get to the less webby portion of the feather, clip off and start another webby base.

Continue this process until you fill the shank to the eye. If you are doing a bi-color version stop when there is a small area left, use a slightly stiffer less webby hackle of another color and continue wrapping the shankf full to right behind the hook eye.. Whip finish a small head and seal with cement.

Some substitutions if you wish:

Use strung marabou instead of the bases from webby hackles.
Add a single wrap of webby red hackle between the two colors of hackle or a short distance from the tie-off point to simulate gills.
Take a permanent ink marker and add details to the hackle.
Add a mono or wire weed-guard if fishing heavy cover or vegetation.
You can add weight to the hook shank if you want to, but the beauty of this fly is it's slow sinking ability and ability to suspend in the water.
