Video: How to Tie the F-Fly

Marjan Fratnik was a Slovenian angler and fly tier born in Most na Soči–at the confluence of the now famous Soča and Idrijca rivers–in 1919. Known for his simple yet effective patterns, he is most well known for the F-Fly, perhaps the most popular Slovenian pattern of all time. You can read a great history of Fratnik and his flies on

In this week’s great video from Tim Flagler of Tightline Productions, he teaches you how to tie Fratnik’s impressionistic pattern. Tim uses it as a caddisfly imitation, but tied in various colors, the F-Fly is a great, low-riding pattern that can represent a wide variety of insects.
