Tie in thread, wind back and tie in 4 microfibbetts, tips aligned. Using your finger, push them up to help keep them in position while you separate them.
Grab the far 2 microfibbetts and pull them up, and away. Make a thread wrap between the 2 bunches. Grab the 2 nearest you and make a thread wrap from underneath, up and through the 2 bunches. Make a wrap behind both bunches and a wrap in front to secure the lot. Trim the butts.
Strip a goose biot from the stem and tie in as shown, with "notch" at the base of the biot facing back. Using your hackle plies wind the biot forward, tie off and trim butts.
This recipe is compliments of Rob O'Reily.



Stroke feathers to make it easier to tie in, measure wing to be approx. the length of the hook shank. Tie on, making sure the wing sits on top of the shank, and does not roll around it.
When wing is secure (about 3 firm wraps) trim the butts of the CDC feathers, trying to make sure they are cut so that the thorax will dub with a nice taper. (trim at an angle)
Begin dubbing the thorax behind the wing. Lift the wing and force it back as shown. The feathers are tied in flat, thats how they want to stay. Use some force. The dubbing alone can’t hold that wing in an upright position. Dub in front of the wing, tight against it with a few wraps. Using the thread, form a small thread head and tie off.
Select 3 or 4 Type 1 CDC feathers and stack them as shown, with tips aligned.
Using 2 hands, pull the sides of the wings down to create a "fan" shape as shown. If necessary, push back some more. You can make minor adjustments to the position of the wing once its bound in an upright position.
