Here’s the pictures to accompany my previous post on reverse coiling:
The first loop. To make this loop, my right hand is twisting the cable anticlockwise.
Making the second loop. This time my right hand is twisting the cable clockwise, the opposite direction to the first loop.
Another view of how to make the second loop.
And it’s done! If your cable is longer than mine, just keep alternating between clockwise and anticlockwise loops. When the cable is uncoiled, the twists will cancel out and the cable will sit flat.
