In this example we've used white calftail. Some use deer hair and colours are optional although white has become the favourite. Greyhackle applies head cement to secure the tails.
Again, the hackle colour is up to you - grizzly in this example. The UNDERSIDE of the hackle should face forward on all dry flies.
Generally deer hair although some use elk. Again, colour is optional - in this case natural deer hair.
Starting at the bottom, hair tips pointing forward, loosely tie in a generous clump of hair and wind 3 or 4 tighter turns of thread as the hair spins around the shank of the hook.
Continue spinning forward until you reach the head of the fly. It looks pretty awful at this point but don't despair! Use a SHARP pair of curved scissors and start trimming.
Greyhackle turns the hook upside down at this point to see how the fly looks from the underside which is what the fish see! Take extra care not to cut your thread, tails or hackle. Trim until you achieve the desired body shape.
Wind the hackle forward, evenly spaced, tie off, finish the head and presto!
