Materials Needed

Before you begin your knitting journey, gather the following materials to ensure a smooth and enjoyable crafting experience:

  • Yarn: Worsted weight cotton or cotton-blend yarn in three shades:
    • Lagoon Teal (A) – approximately 80 yards
    • Sandy Shore (B) – approximately 70 yards
    • Seafoam White (C) – approximately 70 yards
    Total approximately 220 yards. A cotton blend is recommended for breathability and structure, perfect for summer wear.
  • Needles: US 7 (4.5 mm) 16-inch circular needle and double-pointed needles (or a long circular needle for magic loop technique)
  • Notions: Stitch markers (at least 4), tapestry needle for weaving in ends, scissors
  • Gauge: 18 stitches and 26 rows = 4 inches in stockinette stitch, after blocking. Always knit a gauge swatch to ensure your hat fits perfectly!

Step-by-Step Instructions

This hat is worked from the top down in the round, using a combination of stockinette, reverse stockinette, and a simple lace-like eyelet pattern to create a rippled, organic texture reminiscent of water and sand. Follow these detailed instructions carefully, and you'll have a beautiful sun hat in no time.

Abbreviations

  • CO: cast on
  • K: knit
  • P: purl
  • K2tog: knit two together (decrease)
  • YO: yarn over (increase, creates an eyelet hole)
  • PM: place marker
  • SM: slip marker
  • St(s): stitch(es)
  • Rnd(s): round(s)

Pattern Notes

  • The hat is worked in continuous rounds; use a stitch marker to track the beginning of each round. Place a unique marker (different color) at the start of the round to easily identify it.
  • Color changes are made by simply dropping the old color and picking up the new one at the start of a round, carrying the unused yarn loosely up the inside of the hat. Be careful not to pull too tightly when carrying yarn, as this can pucker the fabric.
  • When working the eyelet pattern, ensure your yarn overs are not too loose or too tight – they should be consistent with your regular tension to create even, beautiful holes.

Crown

With color A, CO 8 sts. Distribute onto 4 DPNs (2 sts each). Join in the round, being careful not to twist. Place a marker at the beginning of the round.

  • Rnd 1: K all sts.
  • Rnd 2: (K1, YO) around – 16 sts. (You'll have 4 sts on each needle)
  • Rnd 3: K all sts.
  • Rnd 4: (K1, YO) around – 32 sts. (8 sts on each needle)
  • Rnd 5: K all sts.
  • Rnd 6: (K2, YO) around – 48 sts. (12 sts on each needle)
  • Rnd 7: K all sts.
  • Rnd 8: (K3, YO) around – 64 sts. (16 sts on each needle)
  • Rnd 9: K all sts.
  • Rnd 10: (K4, YO) around – 80 sts. (20 sts on each needle)
  • Rnd 11: K all sts.
  • Rnd 12: (K5, YO) around – 96 sts. (24 sts on each needle)
  • Rnd 13: K all sts.
  • Rnd 14: (K6, YO) around – 112 sts. (28 sts on each needle)
  • Rnd 15: K all sts.

Body (Increase for Head Circumference)

Switch to the circular needle. Continue with color A. This section will shape the hat to fit a head circumference of approximately 22 inches.

  • Rnd 16: (K7, YO) around – 128 sts.
  • Rnd 17: K all sts.
  • Rnd 18: (K8, YO) around – 144 sts.
  • Rnd 19: K all sts.
  • Rnd 20: (K9, YO) around – 160 sts.
  • Rnd 21: K all sts.

Textured Pattern – First Section

Now begin the beautiful textured pattern that gives this hat its unique, wave-like appearance. Work the following 8-round repeat twice (16 rounds total). This pattern combines knit, purl, and eyelet stitches to create the rippled effect.

  • Rnd 1: With A, K all sts.
  • Rnd 2: With A, P all sts. (This creates a purl ridge)
  • Rnd 3: With B, *K2tog, YO, K1, YO, K2tog, K3; repeat from * around. (This creates the eyelet pattern – note that the K2tog decreases balance the two YO increases, keeping the stitch count at 160)
  • Rnd 4: With B, P all sts.
  • Rnd 5: With C, K all sts.
  • Rnd 6: With C, P all sts.
  • Rnd 7: With A, *K3, K2tog, YO, K1, YO, K2tog; repeat from * around. (Notice this is the mirror image of Rnd 3, creating a balanced, symmetrical pattern)
  • Rnd 8: With A, P all sts.

Repeat Rounds 1-8 once more to complete the second repeat of the textured pattern.

Transition to Brim

After completing the second repeat of the textured pattern, switch to color B and work in stockinette (K every rnd) for 6 rounds. This smooth section provides a visual break and prepares the hat for the brim increases.

Brim

Switch to color C. Work in garter stitch (K1 rnd, P1 rnd) for 4 rounds. Garter stitch creates a sturdy, non-curling edge that's perfect for a brim.

Then work the following increase rounds to flare the brim out elegantly:

  • Rnd 1: *K8, YO; repeat from * around – 180 sts. (20 sts increased)
  • Rnd 2: K all sts.
  • Rnd 3: *K9, YO; repeat from * around – 200 sts. (20 sts increased)
  • Rnd 4: K all sts.
  • Rnd 5: *K10, YO; repeat from * around – 220 sts. (20 sts increased)
  • Rnd 6: K all sts.

Textured Pattern – Brim Section

Now work in the textured pattern again, but with a wider repeat to accommodate the increased stitch count. The pattern is the same concept, just with more knit stitches between the eyelet sections.

  • Rnd 1: With A, K all sts.
  • Rnd 2: With A, P all sts.
  • Rnd 3: With B, *K2tog, YO, K1, YO, K2tog, K5; repeat from * around. (The K5 instead of K3 accommodates the increased stitch count)
  • Rnd 4: With B, P all sts.
  • Rnd 5: With C, K all sts.
  • Rnd 6: With C, P all sts.
  • Rnd 7: With A, *K5, K2tog, YO, K1, YO, K2tog; repeat from * around.
  • Rnd 8: With A, P all sts.

Repeat these 8 rounds once more to complete the brim's textured pattern.

Edging

Work in garter stitch (K1 rnd, P1 rnd) with color B for 4 rounds. This creates a finished, sturdy edge that will help the brim hold its shape.

With color A, bind off all stitches loosely. Important: Use a larger needle (US 8 or 9) or a stretchy bind-off method (such as the Elizabeth Zimmermann sewn bind-off or a knit-two-together bind-off) to ensure the edge remains flexible and doesn't pull in.

Finishing

Weave in all ends carefully using a tapestry needle, making sure to secure them on the inside of the hat so they're invisible from the outside. Block the hat by gently steaming or wet-blocking, shaping the brim to lie flat and the crown to fit a head circumference of approximately 22 inches. To wet-block, soak the hat in lukewarm water with a drop of mild detergent, gently squeeze out excess water (never wring), roll in a towel to remove moisture, then shape and pin to the desired dimensions on a blocking mat. Allow to dry completely before wearing.

Pro Tips for Success

  • Gauge matters: Always knit a gauge swatch before starting. If your gauge is off, adjust your needle size accordingly – smaller needles for tighter gauge, larger for looser.
  • Color changes: When changing colors at the start of a round, give the new yarn a gentle tug after the first stitch to keep the transition neat and tight.
  • Carrying yarn: When carrying unused yarn up the inside of the hat, catch it every few stitches by knitting over it to keep it secure and prevent long floats.
  • Stitch markers: Place a marker every 20 stitches during the increase rounds to help you keep track of your pattern repeats and catch mistakes early.
  • Blocking is essential: Don't skip the blocking step! It's what transforms your hat from a crumpled mass of stitches into a beautifully shaped, professional-looking accessory.

This Luminous Lagoon Sun Hat is a delightful project that combines simple techniques with stunning results. The gradient color transitions and textured eyelet pattern create a sophisticated, coastal-inspired accessory that you'll be proud to wear or gift. Happy knitting!
