Start the black thread behind the eye and lay a base back to the start of the bend.
Stack about ten javalina or wild boar fibres (the book calls for three; Matt uses more) and bind them in at the bend for the tail. The hair is not hollow, so it will not flare. Bind the butts forward as underbody and snip them where the front of the body will end.
Return the thread to the bend and catch in the gold wire rib. It adds segmentation and will lock the wingcase down later.
Snip the brittle tips off five or six strands of peacock herl and bind them in at the bend. Cut the remainder in half and bind the second half in at the same point so about ten strands are ready for the wingcase. Keep the underbody slim; the yarn will hide small lumps.
Lay the orange yarn flat along the shank and bind it in with open, fairly tight wraps back to the bend. Advance the thread to where the body will end, leaving room behind the eye for the hackle.
Wrap the yarn forward in touching turns. Spin it one way to lay it flatter, the other way to tighten it into a rope. Seat it with two or three wraps and snip as close as you can.
Gather the peacock herl, keep the strands parallel and uncrossed, and pull it straight over the top of the body as the wingcase. Seat with a couple of wraps, check the position, then snip close. Do not over-wrap here; the rib will lock it in.
Take one wrap of the gold wire at the rear, then four or five open, fairly tight turns forward over body and wingcase. Seat with two or three tight wraps and helicopter off the tag. Bury the little step the wire leaves with a few thread wraps.
Bind in the grizzly dyed yellow hackle by the stem and snip the butt as close as you can. Take about three turns, then seat with two wraps, the second one tight.
Sweep every barb rearward and build a good-sized head over their bases so the hackle lies swept back rather than standing straight out. Snip the hackle tip, sweep the barbs back again and keep building the head until you are happy.
Whip finish, add head cement, and snip or singe any fibre still pointing forward.
