AK Best method:

1) Wrap clockwise
2) After you're done wrapping, hold the hackle tip to the rear of the hook with your right hand (assuming right-hand tyer).
3) With the left, pull back on the hackle collar and the hackle tip at the same time
4) After pulling back with the left, pull the tip forward with the right (but do not let go with the left). A "v" should form in the barbs between where the barbs are trapped in the left and the barbs that are now facing forward. If there are some barbs just barely trapped in the left, use a bodkin to pick them out to face forward.
5) Wrap twice over the resulting "v."
6) Tie off (or dub further if you like a dubbed thorax and then tie off.
