I love the slip stitch pattern in this sweater! I used a darker yarn as the background, to make the foreground really stand out. The square neckline looks great on anyone, and it complements the geometric nature of the stitch pattern. You can work the sweater up in the short sleeve version shown in the photos, or opt for long sleeves instead.
The yarn I used works up at a gauge of 5.5 sts per inch in Stockinette stitch; if you wish to use a different yarn, make sure you find one that will match this gauge.
