Start the copper 8/0 thread right behind the eye and wrap back, stopping just short of the hook point. That is as far back as the body goes.
Take open wraps forward, then set one strand of black stretch floss along the near side of the shank and pull it really tight as you bind it, so it adds no bulk.
Bind in the large gold Holo Tinsel a little ahead of that, wrap back to the same rear point behind the hook point, then advance the thread forward, leaving about two eye-lengths of bare shank behind the eye.
Wrap the tinsel forward in slightly overlapping turns up to the thread, tie it off well and snip. This is the only flash in the whole fly; everything else stays neutral.
Counter-wrap the black stretch floss forward. Keep the first turn tight right at the back end, then open the spacing off for a bold, predominant rib. Tie off with a good pull and snip.
Flatten the thread at the front of the body and split it (a plain dubbing loop works the same). Load it with Canadian raccoon guard hair plus a little underfur, hold it tight while you spread the fibres out evenly, pinch just below and spin the bobbin hard until the rope is tight.
Wrap two to three turns of the raccoon rope, starting right in front of the last body turn and stroking everything rearward before each wrap. Tie off, then brush the collar to pull out any fibres that did not catch.
Strip the fluff off the base of one CDL in Medium Pardo feather and bind it in by the tip with the barred, shiny side facing out. The raccoon collar underneath is what holds this hackle out so it can breathe.
Palmer the CDL forward to the eye, stroking the fibres back and picking them out on every turn, keeping the natural backwards curve. Carry on until the whole feather is used up, right up to the eye.
Tie the stem off with four wraps behind and four in front, snip the stem, and build a small rusty copper head. Do not skip the head, but do not build a huge one either. Whip finish tight and snip.
Brush out any trapped material to pull the hair back nicely, then stroke everything rearward and touch a little Sally Hansen's onto the head, keeping it out of the feathers.
