Ron - I took your zigzag comment as a technical challenge, so I had to revisit this fly. Here is a yellow version, with a black zigzag strip around the body. What a pita!

Needless to say, but I will not be tying the fishing versions with the zigzag strip.
Thanks guys. You are all very kind.
Bill (tye2fish) - You are absolutely right about fly tying being therapeutic. I am going through a particularly rough patch right now. Last Sunday, I sat down to completed my IBF swap flies. When I was done, I realized that tying the flies had put my mind at rest. I find that my mind becomes very focused on the task at hand, and the troubles of the world melts away for a little while. Good therapy & one of the hidden blessings of this hobby.
