Original pattern calls for Henry's Fork Hackle thorax, of which I had none, so I made my own.

hook - Dai Riki 320 #16
thread - MFC 8/0 sand
rib - Midge Krystal Flash pearl
abdomen - dun dubbing
wing - snowshoe rabbit foot
thorax - cdc dun (in split thread)
hackle - grizzly


Part 1

mash barb, start thread; tie in rib and wrap back to bend




dub thread/dub body (sparse) to 2/3 mark






clip a clump of snowshoe, even tips, measure (even with or a bit past the bend), tie in/trim






tie in hackle
