Another version of the CDC looped emergers. Again, this pattern uses the turkey biot - a really subtle and clean pale colour - but I've incorporated a Zelon wing here behnid the CDC loop.
Place this in the water and take a look at look at the synthetic wing - you'll see an effect that I think simulates either damaged or unfolding wings:
Hook: Kamasan B100 #14
Thread: 14/0 Sheer, tan
Body: Turkey biot
Crumpled wing: Zelon - light dun
Loop wing: Natural CDC
