Slide the Bead to the eye (a 2.4 mm tungsten on a 12, 2x long nymph; no extra weight). Start the Brown thread behind it and build a small dam to keep the bead from sliding back.
Tail: six or seven Pheasant tail fibers, rolled between your fingers to separate them, tied in at the bend about a hook gap long with a couple of wraps.
Lift the tail fibers, move the thread up a little, and catch in the Copper wire around mid-shank. Catch the pearl tinsel flashback in at the same spot on the side, binding back so it ends up on top of the hook at the tail.
Take the thread to the two-thirds point, where the body stops. Grip the tail's pheasant fibers in hackle pliers, give them a few twists to hold them together, and wrap them forward to the thread, re-twisting every couple of turns. The first turns lay little down; later turns lay a wider swath. Catch off.
Thorax before rib or flash: two or three strands of Peacock herl (more if it is thin), with the thread left a little behind the bead. Spin them lightly, not into a rope, and take five or six wraps for a thick thorax. Catch off right behind the bead.
Lay the flash forward over the thorax and hold it with two temporary wraps behind the bead, checking it sits on top. Wrap the Copper wire three turns over the pheasant only, then two stacked turns at the back of the herl. Release the temporary wraps, pull the flash back out of the way, and finish the wire up through the herl; helicopter it off. The wire locks the herl in but never mats the flashback.
Fold the flash back over the thorax again, several wraps to lock it, and snip.
Legs: the CDC hackle. Pull the fibers back to make a tie-in point (a small feather if you have one), catch it in with two or three wraps plus a couple to lock, snip the front stub. Take two turns like a hackle, catch it behind the bead, and snip the stem.
Pull the CDC back and fill the gap between the hackle and the bead with a few solid wraps, then whip finish behind the bead.
Bunch the CDC fibers, pinch them at the length you want, and break them off rather than cutting, for a more natural tip.
