Lost a few pics off the disk (hence the mid-stream color change) so I had to tie the d.mn fly twice.
hook - Dai Riki 320 #16
thread - MFC 8/0 brown, errr...UTC 70 tan
abdomen - caribou spun/clipped
wing - deer hair
hackle - brown, errr... ginger
Part 1
mash barb, start thread at the back end; you can spin hair on a wrapped shank, but it's just as easy not to (and the thread savings is tremendous when factored over thousands of flies)
clean a clump of caribou, trim off tips; tie in with 2 soft loops and let it spin
pack it back, half hitch
repeat
one more time; tie off and trim thread
flip it over, lay a razor blade on the eye (to establish the belly) and push straight back
