Here is an quick way to make a herl body reinforced with thread.

Take several herls and trim a little off the tips.
Then tie them in by the tip ends.
Wrap the herl around the tying thread about 4 times.


Grab the end of the herls and thread between your thumb and forefinger and wrap both together, without letting go.
As you wrap the herl and thread will twist around each other.


When you reach your destination, untwist the herl from the thread and tie it off.
