Here's a step-by-step tutorial for tying a Rangeley style streamer like the Grey Ghost. The 'authentic' way (a la Carrie Stevens) of tying these is to build two wing assemblies that includes the wing feathers, the silver pheasant sides, and the jungle cock eyes as single units. Then you mount the assemblies right along the sides of the shank.

It's a different style in that we're used to tying in the wing feathers, then a side or shoulder feather, and then an eye and whatnot. It might be worth a look for any of us who are going to tie a Grey Ghost.
