This is how I tie pheasant tails. Two separate bunches of fiber. One for the tail and body then another for the legs and wingcase. The turkey tail nymph on the other hand is tied with one singular bunch.
Tail- white ice dub brushed out and stacked repeatedly. Pearl crystal flash.
Under body- white cocktail tied in tips forward then pulled back. Flashabou.
Head- white craft fur brush.
Hook- Mustad 2/0 o'shaughnessy
