Unique Striped Crochet Hat Pattern – Geowave Hat

This post may contain affiliate links, view my disclosure policy for details.

The Geowave Hat is a striped crochet hat with a really unique texture! And this crochet hat pattern is definitely simpler than it looks.

This hat is crocheted from the bottom up, starting with the ribbing. And the best thing is, once you get the hang of the first row or two, it’s a one-row repeat for most of the hat body. So, it requires just a little concentration at the start, and then you’re good to go 🙂

The crochet pattern is written for 4 sizes, from Baby up to Adult Large, so this is a great pattern to make in bulk for gifts.

What you’ll need to crochet the Geowave Hat

Yarn

Any #4/Medium/Worsted weight yarn will work great for this pattern. For my hat I used Paintbox Yarns Simply Aran (184m/201yds per 100g skein; Weight 4/Aran; 100% Acrylic).

Some great alternatives (in a selection of different fibres) for your crochet hat include:

Hooks

For this hat you will need two different hooks, a smaller one for the ribbing (to ensure a nice, snug fit!) and then a larger one for the body of the hat.

For my hat, I used a 4mm (G-6) crochet hook for the ribbing, and a 5mm (H-8) hook for the body. You can use any hooks that allow you to meet the gauge listed in the pattern.

Other supplies

The hat is worked from the bottom-up in joined rounds. It is a good idea to use a stitch marker to keep track of the first stitch of each round! You’ll also need a yarn needle to weave in those ends.

How to crochet this unique striped hat

This striped hat is crocheted from the bottom up, using 2 colours of #4/medium/worsted yarn.

Step 1: First, you will crochet the easy single crochet ribbing in a long strip, then fold it in half to seam.

Step 2: Next, you will work the rest of the hat in the round, joining at the end of each round with a slip stitch. This section of the hat might take a little bit of getting used to for the first round or two.

But once you have the hang of the Front Post stitches used to create the “V” shape, you will be able to put the pattern aside for a little while!

Step 3: The final section of the hat is a series of “decrease” rounds, to reduce bulk at the top of the hat, and make it easier to “cinch in.”

Note: the print-friendly PDF version of this pattern also includes a stitch diagram for the entire hat (body and decrease rounds), in addition to the written instructions.

Crochet Hat Sizes

This pattern is written for 4 sizes, as follows:

  • Baby: 17″-19″ / 43cm – 48.5cm
  • Toddler/Child: 19″-21″ / 48.5cm – 53.5cm
  • Adult Small: 21″-23″ / 53.5cm – 58.5cm
  • Adult Large: 23″-24″ / 58.5cm – 61cm

As the hat ribbing is quite stretchy, it is a good idea to make your finished hat 1″-3″ / 2.5cm – 7.5cm smaller than your head size.

Notes

Please read through the entire pattern before beginning.

Skill Level

Construction

  • This hat is crocheted from the bottom up as follows:
    • First, you will work the ribbing in a long strip, then fold in half and seam the edges together.
    • You will work the body of the hat in joined rounds.
    • Finally, you will work some decrease rounds to reduce bulk at the top of the hat, and close up the gap with your yarn needle.

General Pattern Notes

  • Ch 1 at the start of each row/round does not count as a stitch.
  • The stitch count for each row/round is given in [ ] at the end of the row/round.
  • Instructions are written for multiple sizes as follows: Baby (Toddler/Child, Adult Small, Adult Large).
  • Before you start, go through the pattern and highlight/mark the stitch counts and rounds that correspond to the size you are making (this will make your life much easier!).
  • The print-friendly PDF version of this pattern also includes a stitch diagram for body and decrease rounds.

Color Changes

  • The hat body is worked in alternate rounds of C1 and C2.
  • Change color at the end of a round as follows:
    • With C1, join at the end of the round with a sl st.
    • Yarn over the C2 and pull up a loop.
    • At the back of your work, pull C1 gently downwards and to the right. You are now ready to begin the next round with C2.
  • Do not cut yarn between rows; simply float the new yarn up at the back of your work as required for each color change.

Gauge

Ribbing
6 sts x 14 rows = 1.5″ x 4″ / 4cm x 10cm measured over sc (blo) ribbing (with smaller hook).

Special Stitches

Front Post Treble Crochet (FPtr)
Step 1: Yarn over twice.
Step 2: Insert hook from front to back to front around the post of the indicated stitch, yarn over and pull up a loop.
Step 3: Yarn over and pull through two loops 3 times.

Half Double Crochet 2 Together (hdc2tog)
Note: this is a modified hdc2tog in that the first step does not have a “yarn over” as it normally would for a hdc st. This is done to prevent the stitch from “puffing up” too much.

Step 1: Insert hook into indicated st and pull up a loop. [2 loops on hook]
Step 2: Yarn over, insert hook into next st and pull up a loop. [4 loops on hook]
Step 3: Yarn over and pull through all 4 loops.

Half Double Crochet 3 Together (hdc3tog)
Step 1: Insert hook into indicated st and pull up a loop. [2 loops on hook]
Step 2: Insert hook into next st and pull up a loop. [3 loops on hook]
Step 3: Yarn over, insert hook into next st and pull up a loop. [5 loops on hook]
Step 4: Yarn over and pull through all 5 loops.

Cut yarn (both strands) and fasten off, leaving a long tail.

Weave in any remaining ends.

Turn hat the right way around.

All done!
