A lot of variations to the basic framework out there; just one idea here.
hook – Dai Riki 135 #12
thread – Danville 6/0 black
core – 8lb Mason
body/shellback/head – 1mm foam blue
wing – Congo Hair white
thorax – dubbing blue
hackle – grizzly
put a loop in the end of the mono
mash barb, start thread; tie in mono
tie in foam, hook the loop onto the gallows
brush mono with Super Glue, wrap foam up (2x hook length)
brush on some more Super Glue and wrap back down; tie down tag end at base
tie in CH on either side of body
tie in hackle
dub thread/dub thorax
wrap hackle thru thorax; tie off/trim
trim hackle on top, pull foam forward; tie down
fold forward over eye to create head
tie off, half hitch x 2, SHHAN, trim head, trim wing, trim out hackle underneath
