Al Beatty showed me this: For Elk or deer hair, cut 1 flies worth the hair off the hide. Keep the fibers together, all curved in the same direction. Take your thumbnail and pinch the hair with your thumbnail and index finger going up toward the tips about 1/8 of an inch each time. Pinch the hair on the backside of the curve. Works pretty good. You can even comb the underfur out and then do the pinch. Stack it after you made 8 pinches or so.
