Simply Hemmed Hat
Sometimes a gem shines brightest in the simplest setting, and that’s the philosophy we took with our free Simply Hemmed Hat pattern. This easy, quick topper is knit all in smooth stockinette to let you admire the beautiful 100% yak fiber of our Simply Yak yarn, now available in a brand-new undyed color: Natural Taupe!

Yarn made from yak fiber is a truly special experience to knit with and to wear. Most closely akin to cashmere, both fibers are grown by animals adapted to the very coldest conditions, both produce yarns with amazing softness, breathtaking lightness, and a delicate halo… But yak fiber is even more breathable and more durable, too!

Yak fiber relaxes a lot with blocking and wear, which makes it very soft and very lovely but requires thoughtful design. Our Simply Hemmed Hat pattern has a few tricks that are anything but tricky to help your hat keep its shape, like starting with a long-tail (instead of provisional) cast on for structure and using needles a size smaller for the inner hem.

If you’re worried about that hem detail, let us put your mind at ease! It’s an easy technique, and we have a tutorial to walk you through every step. After the hem, it’s all simple stockinette with a beautiful yarn (what’s better than that?) up to the top of the hat, which is shaped with straightforward decreases forming four spokes.

100% undyed yak, combed from the downy, toasty warm undercoat of free-roaming yaks, this light worsted/DK-weight yarn celebrates all that unadulterated goodness with a lofty 2-ply spin that lets the fiber bloom. Both colors of Simply Yak, new Natural Taupe and original Natural Brown, are undyed, just as nature made them… Simply gorgeous.


You only need a skein or two to make a Simply Hemmed Hat, so cast on for yourself or someone really special… We made the pattern with sizes from baby to adult and everything in between, so everyone can experience the wonder that is Simply Yak!

For the baby size do you need to switch needle size or can you just stay with the 4?
Hi Amy,
Thank you for writing in! We used the same size needles for each size of the pattern so we would suggest switching yours as well. I hope this helps clarify but please let me know if you have any questions!
All the best,
Gavriella

Would this hat be suitable for men? Thank you.
Hi Jeanne,
Thank you for writing in! This pattern would make a great hat for men, women and children!
Happy knitting,
Gavriella
This is different, I realy like it.
Would this pattern work with other DK yarns?
Hi Ann,
Absolutely! This pattern would be lovely in a different DK weight yarn as well. I’d just recommend knitting a gauge swatch before casting on your project, especially when you are substituting yarns. You may need to size up or down your needles in order to get the correct gauge! If you would like to learn more about this, we have a handy tutorial called All About Gauge.
All the best,
Lili
can you use magic loop instead of the DPNs?
Hi Judy,
Yes, absolutely! Magic loop is a wonderful alternative to DPNs.
All the best,
Lili
Great directions, beautiful hat and most important it feels fabulous.
I found it impossible to pick up the stitches for this yarn. In my hands, anyway, the yarn immediately fuzzed such that the cast on stitches were undetectable. My question is: if I make this hat again, can I use something like a provisional cast on instead of the longtail cast on to preserve the stitches? I have never made a hemmed hat before and don’t know if that would work. Thanks.
Hi Kim,
You can absolutely use a provisional cast-on to begin this hat! Our Far + Wide Hat and our Picot Hat provide instructions on how to do the knit hem that way. You’d just have a different stitch count, but otherwise it works exactly the same way!
All the best,
Lili
I followed the pattern with the correct gauge and gently wet blocked it, but my hat grew/stretched out far beyond its original measurements after only two wears. This yarn is too beautiful to waste on a hat that I can’t wear, so I’m probably going to rip it out and try again. Any tips for helping keep its shape for the second attempt? I made the Adult Small size.
Hi Kathryn,
I’m so sorry that your first hat grew in size during blocking, and I’m glad that you’re up for trying again! The first thing I’d recommend doing is blocking your gauge swatch, if you didn’t do that the first time. Many yarns grow and bloom when wet blocked, which can change the gauge measurements significantly. So if you plan on blocking your finished project, we always recommend blocking your gauge swatch for the most accurate measurements. Then you can size down you needles if necessary!
All the best,
Lili
Hi I’m a beginner and love to attempt to make this hat. Will it work out if I stuck to the same size needle instead of switching from 4 to 5 size needle when working the cuff? Since I’m just starting out I don’t know how to switch needles. Or do you have a simpler beanie pattern I can follow that has a round top instead of a pointy one?
Thanks so much!
Hi Carmie,
You can absolutely just stick with the same needle size if you want–it only makes a very slight difference! But if you want to give switching needles a try, all you need to do is start knitting with the new needles, and by the end of the round, all the stitches will be transferred automatically as you knit. You’ll get the hang of it super fast!
All the best,
Lili
