Slide the small bead on first, followed by the second oversize bead. The countersunk hole of the larger bead, which normally faces backward, should face the hook eye so the small bead can nest within it. Put the hook in the vise, and wrap thread behind the small bead and tie in two goose biots as shown.

Wrap the thread back to the bend of the hook to create a larger foundation for the oversize bead. Continue to create a thickly tapered underbody so the large bead sits snugly. Whip-finish the thread and clip it off. Slide the large bead firmly against the smaller bead.

Reattach the thread behind the large bead. Wrap the hook shank with 8 to 12 turns of tungsten wire and secure it with thread. The wire and thread dam helps hold the large bead in place. Wrap the thread back toward the hook bend. Add a small dubbing ball and tie the tails on each side of it. Tie in the copper wire rib.

Dub the abdomen to just behind the large bead. Wrap the copper wire forward, tie it off, and clip the wire.

Tie in partridge feather barbules “in the round” so they extend around the circumference of the thorax. The length of the barbules should be approximately half the length of the hook shank.

Use a dubbing loop to create a buggy/shaggy thorax. Whip-finish directly behind the large bead.
