A hat that speaks your language! Knit up in our buoyant Good Wool yarn, our super giftable If You Knit, You Know Hat pattern spells out the secret language of knitters. And while these hats give a wink to those in the loop, you can personalize yours any way you want: initials, acronyms, or even your own inside joke.

A simple folded hem kicks off this charming hat, with the inner hem worked on smaller needles so it gently hugs your head with no need for ribbing. From there, you’ll knit a canvas of smooth stockinette before working four spokes of easy decreases to shape the crown… And just like that, it’s time for the fun part!

Use trusty duplicate stitch and our handy chart of letters and numbers to add whatever knitting phrase, abbreviation, monogram, or message you like. If you’re new to duplicate stitch, it’s wonderfully simple, and our step-by-step Duplicate Stitch Tutorial will help you get a beautiful result.

Cast on with Good Wool, a yarn that sparks your imagination with every stitch… So sproingy, so beautiful and so, well, good! Spun from the fleeces of highland sheep who have adapted to the cold conditions of Peru’s high-altitude Altiplano, this yarn is wonderfully durable, warm, and softer than you may expect, making it just right for classic hats.

You need just one skein of this sport-weight yarn to knit a hat in any of five sizes, plus a little extra for your personalization. Pick up a few skeins of Good Wool so you can knit a hat in each color, then mix and match the monograms with what’s left! With five undyed natural shades and a big rainbow of heathers dyed over them, Good Wool offers endless inspiration for thoughtful, handmade gifts.

Soft, warm, and playful, our If You Knit, You Know Hat says it all… It’s the perfect cozy gift for knit wits and kindred spirits of all kinds!

Love it! You never cease to amaze!
Would this pattern work if I make it using your Cashmere Merino Bloom? I just bought a skein, intending to make one of the basic ribbed hats you recommend for the yarn — then saw this pattern, which would probably knit up a lot faster, without the ribbing. But maybe cashmere merino is a bit soft for this pattern, and needs the structure of the ribbing? If you think it’d work, do I need to change # of c/o stitches?
Hi Anne,
Thanks for writing in! You could absolutely use Cashmere Merino Bloom for this pattern. We always recommend knitting a quick gauge swatch just to check your tension but since this hat uses duplicate stitch you could also use our Simply Hemmed Hat pattern for your base hat and then the duplicate stitch charts for the motif!
Happy knitting,
Gavriella
Would love to see all your patterns!
Pat
What a charming idea. Perfect for me and for gifts!
Could I do this in Echo Cashmere? Any adjustments?
Hi Mimi,
Thanks for reaching out! The gauge for this hat will work with Echo Cashmere, but it will be a less dense fabric. We recommend knitting and blocking a swatch to make sure you are able to make gauge and like the look and feel of the fabric before casting on. I hope this helps but please let us know if you have any questions!
All the best,
Andrea
Would this work in Wigeon, too?
Hi Kristin,
Yes, Wigeon would be a great yarn to use for this pattern! It’s always a good idea to do a gauge swatch before you cast on, most especially when you’re substituting yarns. If you need help with that step, be sure to check out our All About Gauge Tutorial. It will get you off on the right foot!
Please let us know if run into any more questions along the way… We’re here to help!
Best,
Whitney
