No, I don't. After tying in the hackle, i'll bring the thread back up to the head and then wrap the hackle, then tie it off.
I used to do it like that too but found after a strike or two it would break the stem (i know there's a proper word for that but i cant remember it) and the hackle would let go and the fly would be toast. I started tying the hackle in at the eye, wrapping it back to the bend and following it back with the thread and then wrap to the eye again in a zig zag motion. That ensures that no matter where the hackle breaks, if it does, that it will stay put.
I've heard rumblings around here that people don't like to tie these little beauty's lol, i can't figure out why. :dunno:
