Start the black thread behind the eye. Take a small bunch of White calftail, stack it if you like, and bind it in as a wing about a third of a shank long. Take loose-to-medium wraps working back, watching the hook point.
Run the thread back to the bend and bind in about ten White hackle fibers as a tail about one shank length long.
Catch in the Flat silver Mylar tinsel at the rear with the silver side toward the hook so the silver shows when it wraps.
Dub a noodle of the synthetic dubbing on as thin as you can, the calftail butts already thicken the underbody, and wrap the body forward to right behind the wing.
Wind the tinsel rib forward in four or five turns and catch it off. Do not overpower the fly with flash.
Catch in the dry fly hackle with a little bare stem showing, leaving the stem running forward. Pull all the calftail upright and bind the stem down at the same time so the thread props the wing up at about 90 degrees.
Wind the hackle at least three turns behind the wing and three or four in front, then catch it off.
Pull everything back and take wraps to clear a flat area for the whip finish, then snip the excess feather and any fibers pointing forward, whip finish and add a drop of head cement.
