Nice Ties, thanks for sharing!

I tie my parachutes off on the post. I little tricky to learn - at first I would reposition the hook so the post was horizontal (hook eye pointing down) to make the whip finish feel more natural. I eventually got comfortable whip finishing with the fly positioned normally. Wrap the hackle clockwise around the post, and the finer the thread the better the result. With 8/0 thread I use generally use a 3 turn whip and I've never had a problem with the fly unraveling.
