Step 1: The Hook
The best size of late season Grayling dries is either 18 or 20. Due to limitations of my Macro setup I am using #18 to get the best picture quality. The hook is Hanák 130 BL
Step 2: The Thread
Only the finest thread should be used for flies this size; I am using UNI Trico 17/0 unwaxed thread colored white.
Step 3: The Flash
To make the correct choice a bit easier for Mr. Grayling I am adding a little flash to the fly. It may imitate the trailing shuck, or just arouse curiosity of the fish, but it helps me to have confidence in my fly. I am using 3 strands of orange Krystal Flash.
Step 4: The Herl
Many different herls can be used - Heron, Olive dyed Goose, Eagle Owl (the best, but sadly outlawed by CITES) and Ostrich. I am using natural gray Ostrich. The Ostrich herl is sturdy and Grayling are not known for their toothy mouths, but just in case a brownie decides to show up and tear my fly up I am using two strands of the herl. If I were targeting my fly specifically to brown trout I would be including a counter rib of gray 6/0 thread (and making the fly a size or two bigger).
Step 5: The body
Trim the flash and wrap the herl in the direction of tying thread forward almost but not all the way up to the eye.
Step 6: The wing
Trim the butt end of the herl, add 3 CDC puffs to form the wing.
Step 7: Finish
Trim the CDC feathers, form a small head & whip finish.
Take a step back and enjoy your work
Cheers!
