Says Dempsey: "This bias knit long-sleeved cardigan uses handpainted or variegated yarn to full effect. The back is 2 pieces knit on the bias and seamed in the center."
(Ingenious, and gorgeous, and easier than it looks as well as more fun. The armholes are indented once for a modified drop shoulder; sleeve tops are flat. An ideally flattering way to show off any variegate in this very common weight of yarn-- Ed.)
