Part 2
wrap foam forward and tie off (no need to glue the foam since it's going to be ribbed)
rib abdomen, tie off and pull foam back
take a sparse hank of Congo Hair and tie on underside (which is actually the topside on an upside-down fly) at 80% mark; a bit farther forward than normal, but, as noted, trying to improve the hooking
pull down (or up, depending on orientation - very confusing) and add a few posting wraps to gather the wing
tie in hackle
dub thread (sparse), dub thorax
wrap hackle through thorax, tie off and trim
