How to tie it
Seat a gold slotted tungsten bead behind the eye of the jig hook. Start purple thread behind the bead and carry it to the bend.
Tie in 6-8 coq de leon pardo tail fibers about half a shank-length long and bind the butts down to make a smooth underbody.
Build the body: either wind a purple quill forward to just behind the bead, or simply build a smooth tapered body with the purple thread itself (the perdigon relies on the resin coat for its finish). Keep it slim.
Change to fluorescent red thread and, after first winding 2 turns of holographic red tinsel, form a short bright collar of tight thread turns directly behind the bead. Whip finish.
Coat the full body and collar with thin UV resin and cure to a hard shell, keeping resin off the bead face.
