Here is yet another way.

Tie in about 4 herls. Let enough thread out of the bobbin so it's slightly longer than the herls. Wrap the herls around the tying thread three turns counter-clockwise (looking down from the top).


Grab the ends of the herls and the thread together and wrap. As you wrap the herls and thread will continue to twist around each other.


When you get to the tie off point untwist the herls from the thread and tie them off.
