I happened to view several videos of tyers tying 'upright and divided' dry fly wings. There was a variety of materials used but wood duck was the one used most often. It was interesting to see the various ways that the tyers performed the task and managed to get similar results. At least they looked similar in the video. Perhaps examining the flies close up would've revealed differences that may or may not be important or simply personal preference. Anyway, I did not see the method I use most often and which was taught to me by 2 exceptional tyers, both were 'experts', multi-published authors, and are no longer with us.
Anyway, what method do you use the most to tye 'upright and divided dry fly wings'?
