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.
