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!
Designed for Purl Soho by Jake Canton.
Materials
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 A: 2 skeins of Purl Soho’s Good Wool, 100% Andean highland wool. Each skein is approximately 383 yards/100 grams. We used Heirloom White.

- 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.

Love this pattern, thank you PS!! 🙂
It appears that the natural color is worsted weight, and the colored yarn is DK weight.
Is that correct? Thanks!
Hi Jennifer,
Thanks for reaching out! You are correct that Good Wool can knit up at either a light worsted or a DK gauge, while Mulberry Merino is a sport weight yarn. The difference in weights is fairly minimal so they work quite well together both for this hat and cowl set and our Double Knit Blanket.
Happy knitting!
Julianna
Love the cowl & just want to make the cowl only.
How many skeins would I need? My thought is one heirloom white & 2 Mulberry Merino…..making the circumference slightly shorter. Appreciate your thoughts on this.
Hi Elaine,
Thanks for writing in! We used almost all of one skein of Good Wool and two skeins of Mulberry Merino for the cowl alone, so this should still be a good amount even if you are making the cowl a bit shorter.
I hope that helps!
Julianna
The pattern Corrugated Cowl, how do I print off a copy? There’s no load tab. Could you provide a link or pdf, please. I sure hope so. Thanks so very much.

I hope that helps!

I’m thinking of making these pieces in 2 colors of Good Wool only.
I like the neutral colors and the price. Wondering, though, is Good Wool scratchy at all?
Thanks for your time!
Hi Lee,
Thanks for reaching out and what lovely idea – I love using the natural colors of Good Wool together for colorwork projects! Good Wool does have a hearty, pleasingly rustic texture, and although it is not as soft as merino, I find it plenty soft for next-to-skin wear.
Best,
Julianna
Reading the pattern I noticed for the hat no yarn C was listed and for the cowl no yarn B was used
There must be an error. Thank you for checking.
I love the look of the photo.
Hi Joan,
Great question! This is correct! We use the same color of Good Wool for both the hat and the cowl but different colors of Mulberry Merino for each. So for the hat, you will use colors A and B and for the cowl, you will use colors A and C! As the colors of Mulberry Merino that we put together for each bundle are coordinating, you will get a hat and cowl that have a similar look and feel but slightly different colors!
I hope that this clears things up!
Cassy
Thank you, now I understand, the hat and
cowl are slightly different
Hi, is this cowl doubles around the neck? Fifty five inches seems to wide to not be but it doesn’t look doubled in the picture.
I noticed the good wool in heirloom white is a dk weight. I have 2 skeins of cashmerino Bloom in wheat as I changed my mind on a project. Could I use that instead of the good wool if I am only making the cowl? Alternatively, is there any reason to not do the cowl in all mulberry merino? Would think it would be a bit softer and less itchy. Thanks lisa
Hi Lisa,
Great questions! Yes, although the second layer is hard to spot, our model is wearing the cowl wrapped twice – it is quite long! We love using Good Wool because of its generous yardage and interesting texture, but substituting either Cashmere Merino Bloom or another color of Mulberry Merino would be a wonderful alternative.
Happy knitting!
Julianna
I would like to make just the cowl but I notice that the white color in the good wool is sold out. What is a good substitute? Would it work to use 2 different colors of the mulberry merino or do you need different textures of yarn to show off the stripes? Thank you!
Hi Judy,
I’m so sorry that we are out of stock of Good Wool in Heirloom White! You could definitely substitute either another color of Mulberry Merino or Cashmere Merino Bloom – while Good Wool does add a bit of texture, as long as you use two contrasting colors, the stripes will still stand out quite well!
Best,
Julianna
What cast-on method would you recommend for the cowl? I wish more patterns would indicate this. (I know many people have a preferred method that they use for everything but I’d like to know what the designer thought was the best for any given pattern.)
Hello Trish,
Thank you for reaching out! I reccomend using a long tail cast on for this project.
Happy knitting!
-Marilla
I want to make adult medium size hat only, so only one skein each of A and B?
Thanks just double checking
Hello Beth,
Thank you for reaching out! You are correct, to make just the hat you will only need yarns A and B.
Happy knitting!
-Marilla
I am making the hat portion of this pattern. On the shaping of the crown, at the ends of decrease row 1, I am only counting 5 stitches decreased rather than the 8 as stated. The same goes for decrease row 3.
Hi Jane,
Thanks for reaching out! After completing the decrease set up round, you should have four markers, including the beginning of round marker, dividing your stitches into four equal sections. When working each odd numbered decrease round, you will be repeating the entire bracketed section, which begins with a ssk and ends with a k2tog and k1, in each quadrant of the hat, so you will be decreasing 8 total times. I suspect when reading the repeat you missed going all the way back to the first bracket!
I hope that clears things up!
Julianna
Thank you for the clarification. That is exactly what I did. Love your patterns, videos, and comment sections. They have solved so many questions for me. And of course, love all of your yarns. They are exquisite. Wish you would open a branch in St. Louis. There is nothing like tactile capabilities.
Gabbie,
The yarn suggests needle sizes 4-6, however, the pattern states needle size 7. Why?
Thank you,
Tiffany
Hi Tiffany,
Thanks for reaching out! The Corrugated Rib stitch tends to create a denser fabric than most stitches, so we went up a needle size to counteract this. The recommended needle sizes on the label are a suggestion but often depending on one’s personal tension as well as the nature of the stitch you are using, you may need to use a larger or smaller needle than is recommended.
I hope that clears things up!
