How to tie it
Slide a fluorescent-orange plummeting tungsten bead onto the hook and seat it against the eye. Start black thread behind the bead and run a base to the bend.
Tie in a black 1/8-inch rabbit strip at the bend for the tail, about a shank-length long, and lash the front of the hide up the shank as an underbody.
Dub a slim, slightly tapered body of UV black Ice Dub forward to just behind the bead.
Tie in a black schlappen feather by the tip and make two or three turns as a soft, mobile collar behind the bead; tie off and stroke the fibers back.
Build a small thread head against the bead, whip finish and cement.
