Since so many people either ask what a steek is or cringe at the thought of cutting one, I kept a running picture diary of this sweater.
I knit the sweater in the round up to the armhole. Then I put 7 stitches on a piece of yarn for the armhole and cast on 10 stitches for my steek. It was done by long tail cast on since I had two strands, and I alternated the color since steeks are usually done in alternating colors, I guess to keep them nice and tight.
