Slide a slotted tungsten bead to the eye and start the thread behind it.
Tie in a sparse tail of Coq de Leon fibers at the 75% mark, about one shank length long, and wrap the thread base smoothly back over the shank.
Tie in a strand of yellow Flex Floss at the rear and wrap it forward in touching turns to build a slim, tapered body up to just behind the bead; tie off and trim.
Switch to fluorescent orange thread and build a short hotspot collar right behind the bead.
Whip finish, then coat the entire body and collar in a thin layer of UV resin and cure for a glassy, fast-sinking finish.
