Bruce Grant in his "leather Braiding" book presents an interesting method of storing cord that he calls a "Tamale".
I used a 4" wide board here and 10 1/2' of 325 paracord.
Attach Standing End to fixed point.
There are 6 steps in the process.
1. Wrap cord around board.


2. Bring side Up and Over to new position.


3. Bring edge A clockwise 180 degrees.


4. Wrap cord around board.


5. Turn side A counter-clockwise 180 drgrees.


6. Bring side A Up and Over to original position.
