Thomas Zullich talks us through the fairly simple process of tying a Griffiths Gnat.
In order to replicate this fly you will need:
A Partridge SLD hook or other Dry Fly hook equivalent (E1A, L5A, L3A)
Thread
Two Peacock hearls
Grizzly saddle feather
This is a good fly to tye once you have tyed the Red Tag (recipe found here) and before moving on to completing the Klinkhamer Special (recipe found here).
