Lay a base of black thread from the front of a size 14 1XL barbless hook back to the start of the bend.
Tail: catch in a sliver of red floss about an inch and a half long, fold the excess back over the tie-in point, and trim the tail short — not too long, not too short, just noticeable past the bend.
Bring the thread forward and catch the components in the opposite order to the one you will wrap them in: fine wire rib first, then the hackle, then the herl.
Catch in a light brown hackle for the honey dun called for in the recipe; a barred ginger stands in fine.
Take about three strands of peacock herl and bind them in at the rear.
Leave the thread hanging around the middle of the shank. With multiple herl strands that hanging thread will trap them if they start spreading, so there is no need to spin them together first.
Wrap the peacock herl forward in touching turns to build the body as thick as you want, and catch it off up front.
Snip the herl stems rather than breaking them — they are getting thick at the front.
Palmer the hackle forward in very open wraps, not close together at all, and tie it off at the front.
Wrap the wire rib forward in four or five turns, zigzagging it through the hackle barbs to trap as few as you can, then tie off and break away the excess.
Stroke the hackle back to make room, build a small wet-fly head and whip finish.
Optional: singe the stray barbs around the eye with a thread burner, then add a drop of head cement.
