The Siw Sweater Man is worked top-down with a circular yoke formed by increases spread across four rounds. The neckline is first knitted in rib, which is folded and stitched together (or optionally finished as a turtleneck), and then continued in stockinette with colorwork across the yoke and body. The sleeves are knit straight down and finished with a ribbed cuff. The sweater is seamless.

If knitting with unspun yarn, like Nutiden, Italian cast-on and bind-off techniques can be challenging. The pattern provides alternative methods to achieve a beautiful result with unspun yarn.
