This pattern is really an open pattern to use a graphing to make in any gauge and type of yarn. All you need is a loom that is in increments of 18 or a loom you can place into increments of 18.
I have placed in the PDF the different number of peg looms or set ups you can use to make.
I also give photo tutorials on the cables, plus you can get the cable videos in which ever handedness you are.
This is a good pattern to learn how to read graphs and incorporate basic techniques of cables to do so.
Get the pattern and have fun with it!!!
