  2. Select 3 pheasant tail fibers and hold fibers back and upward to ensure they remain on top of hook.
  3. Attach wire rib at tail.
  4. Tie in turkey tail feather used as wingcase on top of hook. Select a second tail feather and tie in at same point
  5. Select 2 aftershaft feathers and tie in separately at tail.
  6. Wire, turkey tail feathers, and aftershaft feathers should extend over tail.

  8. Pull aftershaft feathers forward and tie off with 3 – 4 thread wraps and trim.
  9. Pull turkey tail feathers forward, one at a time, and tie off. DO NOT TRIM.
  10. Wind rib forward and tie off. Trim excess.
  11. Pull both turkey feathers back over body and use a few thread wraps to secure while the thorax is tied.
  12. Dub a thick thorax. Trim top and bottom of thorax to create a flat profile.
  13. Create a V in the leg feather and tie in stem with fibers flowing towards tail.
  14. Pull each turkey wingcase feather forward separately, ensuring legs extend out of each side, and tie off.
  15. Use 5 Minute Epoxy or UV Resin on the thorax section of wingcase.

This is a great Mike Mercer fly pattern from his book entitled Creative Fly Tying.
