This is a basic soft hackle pattern using a nontraditional material as both thread and body material. While the pattern itself is good, particularly in lakes, the key purposes of this video are: 1.) To demonstrate the method by which I use feather barbs from game bird or large hen hackle feathers to tie soft hackles of any size. 2.) To show the thread discipline required to tie such small flies with such a heavy thread.
Hook: 1x strong, 1x short wet fly hook, #12-18. Here, MFC #7077.
Thread/Body: MFC Midge Body Thread, here golden olive. Veevus makes a similar material, and Kreinik (a crafting company) has a material called Blending Filament which is probably the root material for both fly fishing-specific versions.
Hackle: Waterfowl or hen hackle fibers stripped from the feather, tied in facing forward, and spun around the hook shank.
