Superfine dubbing Tan dubbing (A thin noodle for the body)
CDC Tan cdc (One or two feathers, stripped and bundled, for the underwing)
Mallard flank feather Dyed tan (dyed wood duck or olive-gray also work) (One, pre-soaked, for the wally wing)
Saddle hackle Dark barred ginger (or brown) saddle hackle (One feather sized to the hook)
How to tie it
Start brown 14/0 thread about two thirds of the way forward on a #14 TMC 2487 and leave a long tag end hanging. You will use it as the rib. Wrap back over the tag down around the bend and bump the thread so it does not slide.
Spin a thin noodle of tan Superfine on the thread, starting sparse and thickening slightly. Use the bare thread between the dubbing and the hook to get back to the bend so your first turn of dubbing lands right at the bend, then wrap a slim, gently tapered body forward to about the 65% point.
Counter-wrap the brown thread tag forward over the body in evenly spaced open turns for segmentation, tie it off with a few turns and clip it.
Strip one side off a tan CDC feather, peel off a clump and bundle it into a neat bunch. Lay a thread base up to the eye and back to the front edge of the body, then tie the CDC in firmly on top as an underwing. Angle your scissors in to trim the butts and anchor them.
Even the underwing by holding the fibers just past the bend and breaking them off with your thumbnail rather than cutting them square, so the tips stay random.
Prep a pre-soaked tan mallard flank feather: strip the fibers off the base, then create a separation point on each side of the center stem and draw the fibers back. Blot it so it is damp but not soaking.
Keeping the feather flat and unrolled, lay it right on top of the shank with the center quill dead centered and anchor it with three or four turns. Lift the center stem, take a couple more turns over just the fibers, then trim the stem out and clip the remaining butt fibers with the very tips of your scissors.
Make the wally wing: on the far side, separate out a few fibers to use as a handle and pull the MAIN STEM away from them so the feather skins down into a shaped wing half. Repeat on the near side. Lift out the center quill, trim it, snip off the little handles, and preen the two wings into a slightly spent position.
Tie in the dark barred ginger saddle hackle at the base of the wings, add a small pinch of dubbing over the tie-in area to build a slight taper, then wrap the hackle forward over it in close turns and tie off.
Trim the excess hackle, take a few wraps to build a small head, whip finish and cement.
