I adore the shape of the blue one! Can't say I love the stripes, I think it would look incredible in two different shades of Subtle Drifter striped together, or just let the Drifter do its thing. But, you are not me, and you can do you! You SHOULD do you.
This has been knitted in King Cole Drifter and Subtle Drifter DK, but you can use any King Cole DK yarn. You'll need 3.75mm and 4mm needles, as well as a cable needle for the sweater with the cable trim.
