How to tie it
Start thread behind the eye and wind to the bend.
Tie in a few moose body fibers for a short tail, about half the shank.
Tie in copper wire at the bend, then dub a slim black beaver abdomen over the rear two-thirds.
Counter-wrap the copper wire forward as a rib and tie off.
Tie in a bunch of moose fibers pointing forward, dub a fatter beaver thorax, then pull the moose fibers over as a wingcase and split the tips back as legs.
