Browsing through the old ff-ing mags I found some flies Jack Gartside tied up that looked pretty cool. He wrapped the aftershaft as is; I tend to break them off tying that way so prefer to insert in split thread. A little different look here than traditional partridge/India hen/gamebird hackle.
hook - Mustad 3906B #12
thread - Danville 6/0 brown
body - peacock herl
hackle - aftershaft feather (sharptail grouse used here)
Part 1
mash barb, attach thread
take some peacock herl, trim ends even, tie in and wrap back
slightly twist herl with thread for re-enforcement (alternate would be to rib with fine wire) and wrap forward to create body; tie off peacock and trim
pull off an aftershaft feather; insert in clip (makes it a lot easier to manage)
