How to tie it
Mount the hook and lay 10-12 touching turns of 0.015 in. lead-free wire over the front half of the shank, stopping short of the eye. Start black 70 denier thread behind the wire, break off the tag, and lay a thread base back to just past the start of the bend (where the barb would be).
Tie in a good-sized clump of golden pheasant crest fibers there for the tail. Catch them in with a couple of wraps, check that the bundle is sitting on top of the shank (crest is very slippery and will roll), then add a few wraps back around the bend so the tail angles slightly downward. Bind the butts forward to the back edge of the lead wraps and trim to reduce bulk.
Tie in the brassie-size copper wire on the near side and bind it back to the last black thread turn at the tail.
Tie in one strand of peacock herl at the tail and wrap it forward in touching turns to the front of the lead wraps, burying the step between the wire and the abdomen. Tie off and trim.
Counter-wrap the copper wire forward over the abdomen in five or six open turns, tie off at the front of the abdomen and helicopter the wire off.
Tie in three strands of peacock herl at the front of the abdomen, spin them into a tight rope, and wrap a thorax just a little thicker than the abdomen. Tie off and trim, leaving two eye-lengths of bare shank.
Prepare a small coachman-brown or furnace hen soft hackle: strip the fluff, tie it in by the stem at the front of the thorax with the concave side toward the hook. Take two full turns with hackle pliers, preening the fibers back as you go, then secure with a couple of wraps behind and zigzag through the fibers. Trim the tip.
Preen the hackle fibers back and lay a short thread base in front of them. Stack a sparse pinch of white calf tail and measure it about one body-length long. Pinch-wrap it in on top with several tight wraps, then trim the butts as short as you can, holding them so they do not spin.
Wrap a neat tapered head over the butt ends, starting behind the eye and working back, then finish with a four- or five-turn whip finish and a drop of head cement.
