Beginning at the neck and working in the round with a k2, p1 rib, Purtscher’s pullover increases to a k5, p5 rib before switching to an overall tuck-stitch pattern for the yoke, increasing at regular intervals down to the body in widening diamonds. Body and sleeves are worked separately in stockinette, ending with ribs at the lower hem and sleeves. Tuck sts may be worked from written instructions or charts.
