About eight turns of the 0.015" Weight over the front third of the shank (Matt's is a 12, 1x long nymph). Start the Black thread, dam behind the wire, a few wraps over it, and dam in front.
Tail: three or four fibers of Ring-necked pheasant tail feathers at the bend, not long; a nymph's tails are shorter than the dun's.
Catch the small or medium Oval gold tinsel in right behind the weight and bind it back.
Rake a tuft of Hare's ear dubbing off the cheek of the mask, mostly underfur with a few guard hairs. Wax the thread, dub a noodle, and wrap a buggy body forward to about a third of the way behind the eye.
Rib with about four turns of the tinsel and catch off.
Tie in the Kingfisher feather slip (a duck slip dyed kingfisher blue here, or blue floss) at the front of the body, with a couple of extra securing wraps.
Wax again and dub a thicker clump of Hare's ear dubbing for the thorax so it bulbs above the body.
Fold the slip over the thorax and catch it off, leaving room at the eye for the hackle. Trim.
Tie the Partridge in by the thick end of the stem and take two full turns with hackle pliers (one turn puts down too few barbs). Catch off and snip the stem before building the head, taking care the stem doesn't unwind.
Build a big nymph head and whip finish. If you want the Hare's ear dubbing picked out with a dubbing brush, do it before the hackle goes on.
