This dun imitation is again just a blue print. Change body & tail material, colour size etc and you have a great dun imitation. I fold the CDC wing here,and this is the same method I use to tie any of my angled CDC wings.
The short, cut stems under the wing give support and aid is ability to float. There is less waste and this method results in a neat, durable wing. This CDC will not pull out!
A durable, simple fly, I urge you to give it a try.
For the sequence opposite, the materials I have used are:
Hook: Partridge SLD
Thread: Sheer 14/0 grey
Tails: Coq de Leon
Abdomen: Peacock quill
