Collar Natural case (One aftershaft (philoplume) feather from the pheasant rump)
How to tie it
Start thread behind the eye and wind a base back to the bend.
Strip a bunch of soft marabou-like fibers from the base of a pheasant rump feather and tie them in as a tail one shank-length long.
Dub a rough, buggy body forward over the rear two-thirds of the shank, leaving room for the hackle and collar.
Tie in a pheasant rump ("church window") feather by its tip, then wind two or three turns as a soft, sweeping hackle and tie off; stroke the fibers back and down.
Tie in a fluffy aftershaft (philoplume) feather by its stem and take one or two turns to veil the front of the fly in a soft, translucent halo; tie off.
