Chunky Crochet Hat Pattern using Size 5 Yarn

Sometimes you are just in the mood for a good chunky crochet hat pattern! They work up fast and they’re so cozy! If you have some extra size 5 yarn lying around, this would be the perfect pattern to get it off the shelf!

A unique Chunky Crochet Hat Pattern

One of the challenges of using size 5 yarn for a beanie is that it can easily get “too” chunky. Anything over a size 4 yarn is going to have a good amount of bulk to it. Depending on the stitch you choose, the hat can really build up a lot of weight, especially if you go for a folded brim style!

For this reason, I wanted to get creative with the stitches I chose. I didn’t want this beanie to just be a basic style. I wanted it to stand out.

For the body of the hat I decided to use front post treble crochet stitches. This created some fun lines that were very unique for a bulky style.

To cut down on the bulk of the brim, I choose the herringbone single crochet stitch. It was a good contrast to the vertical lines of the body and it is a sleek stitch that doesn’t add a lot of depth.

Now, don’t get me wrong, this chunky crochet hat pattern is still very chunky!! If you’re looking for something that has a sleek slouch or barely-there feel, this is not it! This beanie is warm and heavy and thick!

I worked with Lion Brand Feels Like Flannel yarn for this project. This is a size 5 yarn with soft pastel speckles throughout. Unfortunately, Lion Brand has quickly discontinued this yarn, even though it only recently made it’s debut! But not to worry, any size 5 yarn will do for this project.

For your convenience, you can browse some size 5 yarn collections at Lion Brand, Michaels, Joann’s, and Hobby Lobby.

And if you’re set on trying the Feels Like Flannel yarn, you can often find discontinued yarns for sale on websites like Etsy, Ravelry, and eBay.

4” x 4” swatch of FPtr as directed in pattern = 5 1/2 rows x 11 stitches
(Gauge is not terribly important since instructions are given for adjusting the size of the project by changing stitch count. But designers gauge is included for those that would like to reference it.)


Pattern instructions and gauge will result in an Adult Small = 20” band circumference x 8 ¼” tall (without pom pom)
Instructions for adjusting size also included

Stitches Used:

  • (ch) chain
  • (sl st) slip stitch
  • (sc) single crochet
  • (hsc) herringbone single crochet                                                  
  • (tr) treble stitch
  • (FPtr) front post treble stitch         

Pattern Notes:

Beginning chain of each round does not count as a stitch.

This pattern is constructed by crocheting the hat in a tube shape (first the body, then the band) and then cinching the top shut to complete the beanie.

I tend to crochet tightly. So be sure to adjust your hook size if needed to reach desired hat size. Pattern instructions at designer’s gauge will result in an adult small, but this beanie is easy to resize if needed. Simply add or remove chains from the first line of the pattern to increase the band circumference. To adjust height, add or remove rows at round 8 before moving on to the band in round 9.

This pattern makes a very thick and bulky hat, especially if you’re using the recommended yarn. It holds it’s shape, as opposed to flopping over like a slouchy beanie.

Be attentive to your stitches in round 9 and beyond (the brim of the beanie). The herringbone single crochet can be easy to stitch more tightly. If you find your band shrinking, be sure to keep your tension loose, or perhaps switch to a larger hook.

How to Crochet the Front Post Treble Stitch (FPTr):

Yarn over 2x. Insert hook around the post of the next stitch, from front to back, starting at the right side of the stitch. Send the hook around the back of the post of the stitch and bring it to the front of the project, emerging from the left side of the stitch. Yarn over and pull the yarn back around the stitch and to the front of the project. You should have 4 loops on your hook. Yarn over and pull through 2. Yarn over and pull through 2. Yarn over and pull through 2.

How to Crochet the Herringbone Single Crochet (hsc):

Before beginning a row of herringbone sc, the first stich before the first herringbone sc must be a traditional sc. Then the herringbone stitch will work as follows: Slightly lift the loop on your hook before beginning. This will help loosen the tension, as this stitch is easy to make too tight. Insert hook into the left most bar of the previous single crochet stitch. Insert hook into the next sc. Yo and pull up a loop. Lift slightly again on this last loop so the tension will loosen up. You will have 3 loops on your hook. Yo and pull through all 3 loops.

Photos of the next stitch after completing the first herringbone single crochet:


Before creating your slip knot, leave an 18 inch tail. This will be used to cinch the top of your hat together at the end.
Chain 54. Join with a sl st to make a circle.
Round 1: Ch 3. Tr in the same chain and in each chain around. (About 20 Inches). Join with a sl st to the first tr. (54)
Round 2: Ch 3. FPtr in the same stitch and in each stitch around. Join with a sl st to the first fptr (54).
Note: At this point the width of your circle is approximately the width that the band of your hat will be, but with a little more stretch (the stitches for the band will be more dense). So, if you feel like the sizing is off, you can decide whether to start again with a smaller or larger hook, or with a different chain count.
Rounds 3 – 8: Repeat Round 2. (54)
Round 9: Ch 1. Sc in the same stitch. Herringbone sc in each stitch around. Keep stitches loose so your hat doesn’t shrink!! Join with a sl st to the first sc. (54)

Rounds 10 – 14: Repeat Round 9. Finish off after round 14.

Use the beginning tail and a yarn needle to weave in and out around the first round (the top of the hat). Pull to cinch shut. Tie off and weave in ends.

Optional: Add a pom pom.
