Step One

Begin the pattern by laying a thread base down.

Step Two

Loosely tie on the tip ends of black bucktail material above the hook’s bend to start the tail section.

Step Three

Rotate the bucktail fibers around the shank while applying pressure on the material with your fingers, then crank down on the thread.

Step Four

Pull the tip end fibers back and make several tight wraps in front of the material.

Step Five

Tie two feathers opposite each other on both sides of the shank.

Step Six

Rotate the rotary vice, tie two additional feathers on the shank's bottom, then trim the stems.

Step Seven

Tie four strands of Flashabou at the material’s center, next to the side feather. Fold the fabric on the opposite side of the shank and tie it on.

Step Eight

Loosely tie on another pencil’s width of bucktail material on top of the shank, then rotate the fibers around the shank while applying pressure to the ends.

Step Nine

Tie on four additional strands of Flashabou near the bucktail, then pull the material to the other side and tie it down.

Step Ten

Tie on another clump of bucktail fibers on top of the shank. Once again, start with loose wraps while you twist the material around the shank, then clamp down.

Step Eleven

Trim the outward-facing excess material, sweep the fibers back, then run the thread along the pattern’s neck for a clean look.

Step Twelve

Begin the head by tying on the EP Brush material by the stem, below the hook’s eye. 

Step Thirteen

Take the tip end of the EP Brush, sweep the fibers rearward, and wrap up the shank to the eye.

Step Fourteen

Clean up the fly by running the thread along the shank’s neck and combing the brush material.

Step Fifteen

Tie on the Pro Sportfisher Tabbed Eyes below the hook’s eye, then clip the forward-facing material off.

Step Sixteen

Finish the pattern by securing a half-hitch followed by a whip finish.
