Plain Sailing Ridge Hat Free Crochet Pattern

I wanted to create a super simple hat which could be whipped up in an afternoon, and I love the look of these types of hats. I have made a few in the past, but have often been unsuccessful in getting a hat which fits as I want it to. So here we have it, I wrote a pattern! There are 3 sizes available too: Infant, Child and Adult.

This pattern is available to purchase as an ad-free PDF on Etsy, LoveCrafts and Ravelry. The PDF version includes a lot more detail, pictures and information and is ideal for those who are absolute beginners to crochet. The PDF is designed for printing and has a step-by-step guide, and by purchasing you can support me to make more patterns too!

You will need:

  • 6.5mm hook

  • Chunky yarn: I have used Scheepjes Chunky Monkey*

  • Darning needle

  • Scissors

  • Pompom maker/faux fur pom

*The amount of yarn you need will depend on the size of hat you are making. For all sizes, 1 ball of Scheepjes Chunky Money (116m) is sufficient for the hat- you will need extra to make pompoms


6 rows of 12 BLO Trebles = 10cm x 10cm

Sizes/Foundation chain/number of rows

Infant / 28CH / 22 rows

Child / 31CH / 24 rows

Adult / 34CH / 26 rows


CH: Chain

ST: Stitch

TR: Treble Crochet

BLO: Back Loop Only

SLST: Slipstitch


  • This pattern uses UK crochet terms. A UK treble crochet is an American double crochet.

  • Your turning chain does not count as a stitch throughout. You will begin each row in the stitch at the base of the turning chain, and end each row with the last stitch through both loops of the TR: do not crochet into the turning CH.

  • The pattern is worked flat and joined into shape at the end. You will turn your work at the end of every row.


Foundation Chain:

Use the sizing above to create the right length of foundation Chain. This includes the turning CH so you do not need to add any extra stitches.

You can increase/decrease the starting chain to any amount of stitches, plus 3 turning chain, but I have found these measurements work well!

  • Row 1: TR in 4th ST from hook, and each ST to end. Turn.

  • Row 2: CH3. TR in BLO of each stitch until the end of the row. TR in last stitch of the row through both loops. Do not crochet into turning CH. Turn.

  • Continuing:Repeat Row 2 until you have the correct amount of rows for the hat size you are making as directed above.


Joining and Shaping

Now you have completed an even number or rows, you will need to join them. To do this, CH1, turn your work, and fold it in half. Stitch for stitch, slip stitch the sides together. Once you have finished joining, fasten off and leave a 40cm long tail

Use your long tail to weave through a loop at the top of every 4th row. Pull tight and sew into place. Continue weaving your tail through the loose bits and pull those tightly together. Sew in your ends, and attach your pompom!


I hope you enjoy your cosy hats! Please share your work with me on Instagram using #rocketgirlcrochet
