Supplies
To knit this hat, you will need the following supplies:
- Yarn: ~95g (3.35 oz) medium-weight yarn (category #4). I used Drops Nepal in the color light blue (mix 8913). It’s a blend of 65% wool and 35% alpaca. If you don’t have the mentioned yarn at hand, here are similar yarn options:
- 4mm (US 6) 40cm (16″) circular knitting needles.
- 4.5mm (US 7) 40cm (16″) circular knitting needles.
- 4.5mm (US7) 80cm (32″) circular needles or a set of double-pointed needles (for crown decreases).
- Tapestry needle.
- Scissors.
- Stitch marker.

OCEAN WAVE HAT KNITTING PATTERN
Cast on
CO on 96 sts using the Long-tail cast-on method or the one you prefer.
Join in the round, being careful not to twist the sts (place a marker if you wish to mark the beginning of the round).
I prefer using the invisible join method:
Step 1: CO 96 + 1 extra stitch.

Step 2: Slip the first st purlwise from the left needle to the right needle.
Step 3: Bring the second st from the right needle over the top of the first st (the one that we have passed from the left needle)
Step 4: Put that slipped st from the right needle to the left needle: 96 sts left. Pull on the strands to tighten.

Turn the knitting so the wrong side of the cast-on is facing you. This way, the neat side of the cast-on will be visible when the brim is folded.

Brim
Round 1: *P2, K2* to end.
Repeat round 1 until the brim measures 14cm / 5.5″.

Body
Rounds 1-3: *P2, K2* to end.
Round 4: *P2, C2B* to end.
Repeat rounds 1-4 7 more times. Repeat round 1.

Crown
Switch to double-pointed needles or circular needles with a longer cable (for the magic loop method) when necessary.
Round 1: *P2tog, K2* to end (72sts).
Round 2: *P1, K2* to end.
Round 3: *P1, K2tog* to end (48sts).
Round 4: *P1, K1* to end.
Round 5: *K2tog* to end (24sts).
Round 6: *P1, K1* to end.
Round 7: *K2tog* to end (12sts).

Finishing
Cut the yarn, leaving approximately a 15cm (6″) long tail. Thread a tapestry needle and draw the tail tightly through the remaining stitches. Weave in all loose ends.
