This is a new material for me. Peacock/Or tinsel it is called. It is a tinsel that is copper on one side and "peacock" on the other. I was hooked by the peacock side.
Anyway, I found it at the last show I was tying at, started playing around with it and incorporating it into a couple patterns. This simply was one of my favorites. I think it goes really nice with the partridge and orange. New material, but it keeps that classic look. I waxed the thread with a dark cobbler's wax to give that brownish look.
