The pattern contain two separate PDF downloads, the main pattern contains instructions and the charted instructions, this has been tech edited. The addendum contains both written instructions and a colour-coded chart, which I personally find is easier to work from, I have included them in a separate document so the can be downloaded if required, these have not be tech-edited but both written instructions and colour chart have been tested.
