Lay a base of black thread from behind the eye all the way to the start of the bend.
Tie in the silver tinsel with the gold side up so the silver shows once you flip it to wrap; take about three wraps down and three back, catch it off and snip the excess.
Tie in a slip of red duck almost as long as the body, check the alignment before locking it down, then snip the butt ends.
Tie in the blue floss rib at the rear — spin it clockwise to tighten the strand, counter-clockwise to lay it flat.
Take the thread up to where the body will stop and put in a half hitch to hold it, then wrap the yellow floss forward, back down halfway and forward again to build a taper.
Wrap the blue rib forward counter to the direction the body was wound, re-spinning it clockwise whenever it starts to spread out; do not fuss over the spacing of the last turn or two, the hackle will cover them.
Tie in the brown hen hackle concave side toward the hook, take two or three wraps in front of it and fold the stem back on itself to lock it, then wrap two to two and a half turns with hackle pliers.
Catch the hackle off with two wraps behind, snip the excess, sweep the fibers back and take a few wraps to set them where you want them.
Pair two mallard flank feathers, stripped harder on the underside than the top so the curve stays on top, line up the tips and measure the wing to about midway along the tail; bunch them wet-fly style, pinch wrap on top making sure you get around the hook, then lock them in and trim the butts as close as you can.
Wrap back to the eye and build a ramped head that captures the butt ends, then a four or five turn whip finish and a drop of head cement; pluck any hackle fibers that bunched together.
