Danilo Lazzarini has a unique method of fly tying that is intriguing. I did a little research to learn the technique was shared with Lazzarini by two gentlemen, Valter and Ennio De Santis,  from Rome. How those gentlemen learned or developed the technique, I am not sure. The extended body is not new and has been used for mayfly dun patterns and nymphs. But, I have not seen this method before.
