This design uses simple modular squares, but with the addition of a couple of interesting variations that make this project truly exciting to knit.

Using a single skein of variegated yarn and pooled knitting allows you to knit this entire piece without breaking the yarn even once. The precise use of both stockinette and reverse stockinette allow the contrast stripe to literally pop out from the stockinette stitch background

Because this pattern is entirely dependent upon your yarn, this is a description of the process, rather than stitch-by-stitch directions. Besides creating a lovely cowl, this is a fun exercise in letting your yarn guide the knitting process, rather than you telling the yarn what it should become.

Choosing Yarn
First, you will need variegated yarn. But not just any variegated yarn. For maximum effect, it is important to have very clean color breaks. Ideally, the yarn would be dip-dyed.

The proportion of each color used in the skein will determine the size of the center stripe in each modular square. My skein used approximately 70% of the main color (Color A) and 30% of the contrast color (Color B).
