How to Make a Cable
Making cables is like braiding hair, only you're using two sections instead of three. Once you get the hang of it, you can apply the principle to any number of variations, using different numbers of stitches, different braid directions, or combinations of whole cables to make Aran patterns.
This example uses 8 stitches to make a right direction cable.
The abbreviation for this is CB4 or Cable Back Four.
