The F Fly.

To supplement Alun Rees F Fly patterns I have put together a video of this simple but effective pattern.

Materials:

Hook:  Any dry fly hook ( I prefer down eye) Size to suit the natural on the water

Body:  Tying silk (The choice is yours the example shown is olive but primrose yellow is also a great colour for the Usk).

Wing:  4 CDC feathers  back to back.

Head:  Tying silk
