Another fly in the deer hair body/cross wrap style made popular in Michigan. Feel free to use a contrasting thread; I was going with materials within easy reach. Here's the video if you have 24 minutes (have to admit, I skimmed thru most of it)

hook - Dai Riki 300 #12
thread - UTC 140 grey brown
tail/body/wing - deer hair
hackle - grizzly

Part 1

mash barb, start thread at 2/3 mark; wrap to bend and back

clean, stack, measure (shank length) a clump of deer hair; trim, tie in

spiral wrap body to bend and back, crossing wraps

clean, stack, measure (tips to tail) another clump of deer hair; trim butts/tie in
