Owed this to a friend on another board; apparently a productive fly for sea-run cutts.
hook - Orvis 1645-00 #8
thread - Danville 6/0 black
tail - hackle fibers red
butt - Uni-stretch orange
body - chenille purple
wing - hackle golden badger
hackle - golden badger
Part 1
mash barb, attach the Uni-stretch and wrap back to bend (it'll do double duty as tying thread and butt material for now)
tie in hackle fibers (extend back about 1/2 body length); wrap forward, creating a smooth body
attach black thread and tie off Uni-stretch; continuing back to 50% mark
strip end of chenille (steaming this stuff really puffs it up) down to thread core
tie in, wrap forward to 80% mark and tie off
