Yup, cables are just stitches that trade places on the needles!
Very easy, especially with the use of charts!
Color coding the charts helps IMMENSELY!
Each individual 'symbol' is colored the same.
No mistakes about what gets crossed, and when!
Color code the KEY first, then translate that color coding to your chart.
It helps to make an enlarged copy of the chart in the first place.
On my partial chart (seen above) you will notice that I also wrote in little numbers that tell me if the cable involves 3, 4, 5, or 6 stitches! This also prevents errors.
Cuz doubling back to fit mis-crossed cables is a PITA.
Here is an (partial) example of a KEY that has been color-coded:
