Tying instructions
Secure the hook in the vise.
Slide the brass countersunk bead onto the hook.
Start the thread at the midpoint of the hook shank.
Tie in the pheasant tail fibers for the tail, leaving them bound together.
Adjust the tail length to approximately the hook shank length.
Advance the thread a third of the way down the hook shank, double back to the front, go down another third, and double back to the front again to build a tapered underbody.
Tie in the copper wire for the rib.
Tie in the turkey biot for the back with the curvature facing up.
Dub the body with light Cahill dubbing, creating a tapered body.
Wrap the copper wire forward to rib the body.
Tie off the copper wire and trim the excess.
Pull the turkey biot over the top of the body to create the back and tie it off.
Trim the excess turkey biot.
Dub the thorax with light Cahill dubbing.
Tie in the mallard dyed wood duck for the wing case.
Pull the wing case over the thorax and tie it off.
Trim the excess wing case material.
Tie in the partridge for the legs.
Wrap the thread to secure the partridge and create the legs.
Trim the excess partridge.
