Lay a smooth thread base from behind the eye down and well around the bend, stopping opposite the barb; buzzers ride deep, so carry the body low down the bend.
Catch in the opal oil-slick tinsel at the rear, then a strand of red holographic tinsel for the rib.
Wind the thread forward to the 80% mark in flat touching turns for a slim, even underbody.
Wrap the opal tinsel forward in touching turns to the 80% mark and tie off; the flat tinsel gives the oil-slick shine.
Counter-wrap the red rib in 4-5 open, evenly spaced turns for a segmented red flash, then tie off and snip both materials.
Tie in two short stubs of white antron as breathers, one each side behind the eye, none longer than a hook gap.
Build a small red thread collar, whip finish, then coat the whole body and collar with a thin layer of UV resin and cure for the glassy buzzer sheen.
