How to tie it
Slide a fl. hot orange bead to the eye. Start black thread behind the bead and run a base to the bend.
Catch in a strand of fine copper wire at the bend, then tie in 2-3 strands of peacock herl by the tips.
Twist the peacock herl into a rope with the thread and wrap it forward to just behind the bead to build a plump iridescent body; tie off.
Counter-rib the body with 4-5 open turns of copper wire to lock the fragile herl, then helicopter off the excess wire.
Tie in a partridge feather by the tip just behind the bead and take one or two turns to make a soft, mobile hackle collar; stroke the fibers back so they sweep toward the bend and tie off.
Build a small thread collar, whip finish and cement so the hot bead sits as the head.
