I'm having tons of fun cabling along on Koolhaas. I've never knit anything using a pattern chart before, but it's working out fine. There are TONS of great tips on Ravelry on techniques to make this pattern easier, and above all is knitting without a cable needle.
Grumperina has a great tutorial, and the technique is well worth learning if you even plan to cable. I'm not sure how anyone knit before the internet...
