Part 1

mash barb, start thread at 70% mark (reference point for wing)

clean, stack, measure (hook shank) a clump of calftail

two soft loops (don't let the thread slide forward, then a few more tight ones

trim butts at an angle, then smooth with thread wraps

push the hair up and back, creasing it with your thumbnail; make a thread dam in front with a few firm wraps
