Eric, not sure I completely follow the question .
The main thing is all,twists while making each end are made in the same direction.
Make one end turn it around and make the other end all the between end same way.
While maling the first end occasionly straighten out the end strands to,keep,from tangling.
This method does not use any back twists in between .
When finished add twists to,the whole string hold a end in each hand and look to,see which way each needs to twist they will be opposite directions. Twist as needed to shorten string.
