How to tie it
Run wax through the thread. Start at the eye and wind to the middle of the shank, then back up about two thirds of the way.
Take one or two small olive mallard breast feathers. Strip the fibres so the wing is about an inch long.
Tie the wing in on top, pointing forward over the eye, with three or four turns. Trim the waste.
Wind the thread back down and tie in the brown wire rib, curving slightly round the bend.
Tie in about six pheasant tail fibres for the tail, about an inch long, with three or four turns.
Use the waste ends to start the body. Wind them up a couple of millimetres in the opposite direction to the rib, three or four turns, then tie off and trim.
Dub the body with natural seal's fur and a touch of yellow rabbit, tapering as you wind forward. Trim it to shape if you want.
Rib the body with the wire. Secure it with the thread on the last turn, bend it back and break it away.
Tie in the yellow grizzle saddle by its stem, front of the feather facing you so the fibres sweep back.
Wind the hackle forward to the wing, keeping most of it behind the wing. Come back through it if you want it fuller.
Lift the wing, make a turn of hackle in front, and secure with five or six turns of thread. Trim away.
Draw any forward-pointing fibres back and tidy the head.
Whip finish, trim the thread and add a touch of varnish to the head.
