What intrigues me so much about Pettijean's video is how lifelike the finished fly looks and only has two materials: coq de leon tails, CDC abdomen, CDC wing, and CDC thorax and legs........Pettijean's version has legs of CDC which Smhaen's pattern does not.
This is a beautiful video......in my opinion:
