I actually just started this a couple of weeks ago. The pattern gives charts and written directions. So you can use which ever you prefer.
Also, I'm not an expert, but the way the pattern is written it looks like you could break it into panels and sew it together later. There is a written pattern for each section of cable.
The stitches aren't super hard, but you really have to pay attention to what you are doing, it's not a watch TV while knitting pattern...for me at least!!
