Kotkan Kerttu is a famous Finnish salmon fly created by Hannu Kopra. It has been the trustworthy salmon catcher along the river banks of salmon river Kymi. However I decided to make a little bit more universal version of the fly, by reducing the amount of red colour in it. Normally the fly is tied in a downeyed double salmon hook (Mustad, Loop etc.) But I made a single version of it. Tight lines!
