Found them.

As I said before teal body feathers are often too small for the folding method to work well. I was shown this method for tying teal wings on fishing flies using those smaller feathers. You need a symmetrical feather for this.

Trim the feather up like this.


Tie the stem in place where you want the wing, using two or three loose (bobbin weight) wraps.


Draw the stem away from the eye of the hook until the wing is the correct length. The sides will pull together to form the wing.


Pull on the thread to tighten the loose wraps, you may like to add a couple more wraps as well. Trim out the feather, and form the head.


It's not a way to produce exhibition quality wings, but lets you use up those small feathers.

Cheers,
A.
