The Diamond Knit Hat

I love creating hats that have designs in them, it gives them an added style boost. The diamond beanie has an elegant pattern of diamonds throughout the body of the hat.

The diamond hat is composed of knit and purl stitches. The purl stitches are what creates the diamond pattern in this hat. This hat is beginner friendly and works up fairly quickly, using less than one skein of yarn.

You can purchase the inexpensive ad-free PDF printable version on Etsy HERE  or on Ravelry HERE!

For this hat, I used Loops & Threads Cozy Wool in “Merlot”. You can use any super bulk (level 6) yarn for this pattern. Lion brands Wool-Ease Thick and Quick would be another great alternative.

Notes

  • This pattern is worked in multiples of 12. If you would like to make a smaller sized hat, make sure you are casting on your stitches in multiples of 12.
  • I worked the brim of the hat to about 2″ if you would like to adjust the thickness of the brim you can add more rows for a taller brim, or decrease the number of rows for a shorter brim.
  • Knit two stitches together is abbreviated as k2Tog
  • This pattern is made up of knit and purl stitches

    Very nice! Since brims tend to stretch out I like to use a smaller needle, so will be using an 8.0mm for that part.
    Are your patterns on Ravelry?

  2. Deborah

    What size is this hat? Thank you

    1. northernmoose

      It is for an adult. Sorry I should have specified.

  3. Gina

    I would really love to print these hat patterns but it wont let me

    1. northernmoose

      The printable version of these patterns are available through my Etsy shop. Otherwise you will be printing directly from the webpage, which is why you may be having trouble printing them.

    How much yarn do I need for this hat? Thanks

    1. northernmoose

      It takes less than a skein of yarn. I do not have the exact amount used. My best guess would be between 80-90 yards.

      1. Brenda Warner

        Thanks so much for getting back to me,definitely going to make this hat!

  5. Leen

    Could you help me size this down for a newborn? Or is that asking a bit much?

    1. northernmoose

      Hi there!
      So this hat doesn’t scale down nicely to a newborn size. I’m working on recreating the pattern to include sizes newborn to adult. The pattern should be released early next week!

      1. Leen

        Awesome where will i be able to find it? Also, i began knitting this yesterday and it turned out HUGE! And i was already using a smaller needles size… i love this texture though so im going to try making it again and only cast on 36sts.

  6. Lavi

    Thanks for the wonderful pattern. I really enjoyed the pattern and seeing the diamond shape come through. Thanks so much for detailed instructions.

    Good Evening,

    My head measures 20 inches. Can you suggest how many stitches I should Cast on? I like tight ribbing. Should I use a #11 needles for it and #13 for the rest of the body. I am using Wool Ease Thick and Quick yarn.

    Thanks,
    Rita

    1. northernmoose

      You could try and use #11 needles for the ribbing. I have no tested this out myself, therefore I am unsure of how tight this will make the ribbing.
      Please let me know if you have any other questions.

    Hi! First off, thank you for the pattern!
    I will be using a worsted weight yarn, (the recommended needle size is an 8) should I use that? Or maybe a size 10?
    I’m making this as a chemo cap and really want it to turn out correctly
    Thanks!

    1. northernmoose

      Hi there,

      I would knit using two strands together of the worsted weight yarn. And knit with size 11 or 13 needles. The pattern is written for a chunky yarn, so to follow the pattern using smaller needles, the hat wouldn’t turn out right, unless you adjusted the pattern.

      Hope this helps.

    What length of circular needle did you use love the hat super beautiful thank you for sharing the pattern

    1. northernmoose

      16 inch

  10. Elizabeth

    Is there a way to finish off the hat without switching to dpns? I don’t have any and am wondering if I can just finish it on my circulars. Thank you for the pattern!

    1. northernmoose

      You can just finish off the hat at that row before you switch to the DPNs.

  11. Thelma

    If I finish the hat without switching to dpns how many rows should I add and what would the pattern be for those rows (what stitches would it be)?

  12. Jenna

    When the pattern says p2, *k9, p3* or anything of that sort, am I only repeating the k9, p3 part (the part in the asterisks) or am i repeating the whole sequence?

    1. northernmoose

      Only the part that is in the asterisks!

  13. Rhonda Candell

    My beanie turned out adorable but very small- toddler size. I cast in 48 stitches ,used cozy wool and 9mm round needles, I don’t know what I did wrong but would really love to make adult size. Thank you

    1. northernmoose

      Hello!
      Can you please send me a message through my contact page!

  14. Ruchi

    Hello , 48 cast on include one extra one for joining the end of beanie on row 1 , if we are working on circular needles .
    Or we cast 49 stitches .

    1. northernmoose

      Hello,
      I cast on 48, join my stitches in the beginning before round one. and still have 48 stitches after joining. If your method requires you to have one extra stitch for joining then you’d need to accommodate for that.
      Hope that helps! Have a wonderful night.

  15. Roberta Skinner

    What is the approximate height of the hat? Could it be made into a slouchy hat? Thank you ahead for your response.

    1. northernmoose

      I am so sorry for the delayed response. The approximate height of the hat is about 9″ you could knit a few more rows before the decreases to turn it into a slouchy hat.

  16. Tessa Thomas

    I have made this hat twice and both times it comes out small. Not an adult size I will attempt to use bigger needles this time but also once I get to closing the hat I MESS UP! This is my first hat I have made and I can’t seem to get the closing of the hat down and I am just clueless on what else to do!!

    How many skeins of yarn does it take? Thanks

    1. northernmoose

      Hello, On skein of yarn.
      Have a great night!

      1. Tracey

        This diamond hat is one of my favorites to make of yours and would love to make it with wool. Is it possible to make this hat using #4 Aran wool yarn with 5.5mm needles? If so, how would I calculate the number of cast on stitches and number of rows needed for an adult hat? Obviously, math was not my strong suit in school. Lol. Your feedback would be greatly appreciated. Thank you for the wonderful patterns.

        1. northernmoose

          Hello!
          It would depend on your gauge. But if we were to estimate that your gauge is 4 stitches per inch I would say cast on 72 stitches, and you should be able to follow the pattern as is. If your gauge is closer to 3.5 stitches per inch I would cast on 60 stitches. As long as you have a multiple of 12 you can follow the pattern! As far as the rows go, you would be doing more rows than the pattern calls for. Roughly 44-46 rows and then do the decrease rounds. Let me know if you have any other questions!
          Have a wonderful day!

    I just finished this hat and really enjoyed the pattern. I did not switch to dpn needles, it was tight but I sort of used magic loop techniques to finish. Thanks for the pattern.
