I really loved the stole on the cover, too. I wanted to do it in red like they showed it because I thought it looked really stunning, but I already have some pretty mossy green yarn and it seems a shame to be sitting all lonely in my stash.
I just wanted to mention that the stole on the front cover is crocheted, though (although the pattern looks SUPER easy), but there's no reason why you can't do a knitted version!
The book has helpful information on how to both knit and crochet with beads, and how to achieve certain looks. I think it's quite a good reference tool.
