Here is a fly called the Brassie. There are a few ways to tye this fly, but I prefer the one pictured.
Hook: Mustad 9671 size 14
Thread: Danville Black 6/0
Body: Lagartun Fine Copper Wire
Thorax: One strand of peackock herl from the eye
Before tying in the Peacock herl, add a small coat of head cement in this case hard as hull and wrap the herl forward with the stem side of the herl facing the eye. The head cement enforces the herl and cuts down on the uses of excess material.
