Step #1:
I put a slight dropping bend in the shank with needle nose plies, not mandatory, this just appeals to my sense of aesthetics. Start the white thread mid shank, wind down to a point just past the barb. This marks the body proportions I use for this fly.
Step #2:
Cut a small bunch of moose body hair, clean and stack to even tips. Measure the tail to be about equal with the overall length of the body. Tie in at the mid body point and wrap to the end of the body. Take a couple soft wraps around just the moose hair to help keep the fibers gathered. Add four stands of purple holographic flashabou on each side of the tail, cut even with the tips of the tail.
