Tie in a small grizzly hackle by the tip at the bend, fibers about one hook gap long.
Tie in 2-3 peacock herls at the bend.
Wrap the herl forward in touching turns to one eye-length behind the eye. On tiny hooks, twist the herls around your thread first for durability.
Palmer the grizzly hackle forward through the body in 3-4 open turns.
Tie off, whip finish with a minimal head. Two materials, done.
