From crisp cast ons to exquisite decreases, the design for our Corrugated Hat + Cowl has been considered, tweaked, and reconsidered, so you get to be, “I’m just gonna knit this up, throw it on, and be pretty darn certain it’s going to look amazing!”

Forget complicated… The knitting for this set is really just clever slip stitches that you’ll master in under a minute, and each round involves just one yarn, so you’ll never even have to hold more than one strand at a time.

For our hat and cowl combo, we chose two opposites-attract yarns: our undyed and rustic Good Wool, plus a colorful choice of Mulberry Merino, whose merino-silk blend adds a touch of refinement. We just added 17 stunning new colors to our Mulberry Merino collection, so we were able to use one beautiful color for the hat and a slightly different one for the cowl, making for a pretty stunning duo!

We picked bright Red Poppy and toasty Red Pine for our version, but choose from a rainbow of seven Corrugated Hat + Cowl Bundles, each including two gorgeous colors of Mulberry Merino and two skeins of Good Wool in Heirloom White… And cast on for a truly considered knit!

Our Corrugated Hat + Cowl Bundle includes enough yarn to make both the hat and cowl. We used the Red Poppy + Red Pine Bundle, shown above. It includes…

  • Yarn C: 2 skeins of Mulberry Merino. We used Red Pine.

NOTE: The Hat requires approximately 45 (65, 90, 115, 135) yards of Yarn A and 55 (75, 110, 135, 160) yards of Yarn B. The Cowl requires approximately 370 yards of Yarn A and 415 yards of Yarn C.
