Gauge

To ensure your sun hat fits comfortably, it is vital to check your gauge before starting the main piece. A hat that is too tight will cause discomfort, while a loose gauge will result in a floppy brim that fails to shade your face.

Pattern Instructions

Crown Section

The crown is worked in continuous spiral rounds. Do not join at the end of each round with a slip stitch; instead, place a stitch marker in the first stitch of each round and move it up as you progress.

Round 1: Form a Magic Ring (MR). Note: A magic ring is an adjustable loop technique that allows you to pull the center hole completely closed so no gaps remain. Work 6 sc into the MR. Pull the yarn tail firmly to close the center hole. (6 sts)

Round 2: Work 1 inc in each of the next 6 sts around. (12 sts)

Round 3: [Work 1 sc in the next st, work 1 inc in the following st] rep 6 times around. (18 sts)

Round 4: [Work 1 sc in each of the next 2 sts, work 1 inc in the following st] rep 6 times around. (24 sts)

Round 5: [Work 1 sc in each of the next 3 sts, work 1 inc in the following st] rep 6 times around. (30 sts)

Round 6: Work 1 sc in the next 2 sts, work 1 inc in the next st, [work 1 sc in each of the next 4 sts, work 1 inc in the following st] rep 5 times, work 1 sc in the final 2 sts. Note: Staggering the increases prevents the circle from forming an unwanted hexagon shape. (36 sts)

Round 7: [Work 1 sc in each of the next 5 sts, work 1 inc in the following st] rep 6 times around. (42 sts)

Round 8: [Work 1 sc in each of the next 6 sts, work 1 inc in the following st] rep 6 times around. (48 sts)

Round 9: Work 1 sc in the next 3 sts, work 1 inc in the next st, [work 1 sc in each of the next 7 sts, work 1 inc in the following st] rep 5 times, work 1 sc in the final 4 sts. (54 sts)

Round 10: [Work 1 sc in each of the next 8 sts, work 1 inc in the following st] rep 6 times around. (60 sts)

Round 11: [Work 1 sc in each of the next 9 sts, work 1 inc in the following st] rep 6 times around. (66 sts)

Round 12: Work 1 sc in the next 5 sts, work 1 inc in the next st, [work 1 sc in each of the next 10 sts, work 1 inc in the following st] rep 5 times, work 1 sc in the final 5 sts. (72 sts)

Round 13: [Work 1 sc in each of the next 11 sts, work 1 inc in the following st] rep 6 times around. (78 sts)

Round 14: [Work 1 sc in each of the next 12 sts, work 1 inc in the following st] rep 6 times around. (84 sts)

Round 15: Work 1 sc in the next 6 sts, work 1 inc in the next st, [work 1 sc in each of the next 13 sts, work 1 inc in the following st] rep 5 times, work 1 sc in the final 7 sts. (90 sts)

Round 16: [Work 1 sc in each of the next 14 sts, work 1 inc in the following st] rep 6 times around. (96 sts)

Round 17: [Work 1 sc in each of the next 15 sts, work 1 inc in the following st] rep 6 times around. (102 sts)

Round 18: Work 1 sc in each of the 102 sts around. (102 sts)

Round 19: Work 1 sc in the next 8 sts, work 1 inc in the next st, [work 1 sc in each of the next 16 sts, work 1 inc in the following st] rep 5 times, work 1 sc in the final 8 sts. (108 sts)

Main Hat Sides (The Body)

The sides of the hat are worked evenly without any increases to build the depth of the hat.

Rounds 20–38: Work 1 sc in each of the 108 sts around. (108 sts per round)

The Flared Brim

We will now begin expanding the stitch counts gradually to create a protective, sun-shading brim.

Round 39: [Work 1 sc in each of the next 17 sts, work 1 inc in the following st] rep 6 times around. (114 sts)

Round 40: Work 1 sc in each of the 114 sts around. (114 sts)

Round 42: Work 1 sc in each of the 120 sts around. (120 sts)

Round 43: [Work 1 sc in each of the next 19 sts, work 1 inc in the following st] rep 6 times around. (126 sts)

Round 44: Work 1 sc in each of the 126 sts around. (126 sts)

Round 45: Work 1 sc in the next 10 sts, work 1 inc in the next st, [work 1 sc in each of the next 20 sts, work 1 inc in the following st] rep 5 times, work 1 sc in the final 10 sts. (132 sts)

Round 46: Work 1 sc in each of the 132 sts around. (132 sts)

Decorative Eyelet Mesh Border

This section creates the breathable, open-spaced columns near the edge of the hat brim as seen in image_cb3022.jpg.

Round 47: Sl st into the first st to join the round evenly. Ch 4 (counts as 1 dc and 1 ch space), sk the next st, [work 1 dc in the next st, ch 1, sk the next st]; rep from * to * all the way around. Join with a sl st into the 3rd ch of the starting ch-4. (66 dc, 66 ch-1 spaces)

Round 48: Ch 1 (does not count as a stitch), work 1 sc in the same st as join, work 1 sc directly into the next ch-1 space, [work 1 sc in the next dc st, work 1 sc in the next ch-1 space]; rep from * to * all the way around. Sl st to the first sc to join. (132 sts)

Final Finishing Edging

Round 49: Ch 1, work 1 sc in each of the 132 sts around. Sl st to join. (132 sts)

Round 50 (Wire Insertion Round – Optional): Ch 1. Place your millinery wire along the top of the stitches from Round 49. Working over the wire to trap it securely inside your stitches, work 1 sc in each of the 132 sts around. Overlap the two wire ends by approximately 5 cm ($2″$), secure them tightly with electrical tape or a metal wire crimp connector, and complete the remaining sc stitches over the joined wire section. Sl st to the first sc to join. Fasten off and weave in all remaining loose yarn tails securely. (132 sts)

Assembly Steps

Because this sun hat is crocheted entirely in one single piece from the top crown down to the edge of the outer brim, there is no tedious sewing or multi-piece assembly required!

  1. Wire Finishing: If you opted to insert the optional 1.5 meters of millinery wire during Round 50, ensure that the wire ends overlap by precisely 5 cm ($2″$). Wrap this connection point firmly with clear adhesive tape or specialized millinery tape before completing your final stitches over it. This guarantees that no sharp wire ends pierce through your yarn over time.
  2. Steam Blocking: To give your hat a crisp, professional, high-end look, place the finished hat over a specialized foam hat form, a styrofoam head, or a tightly rolled bath towel shaped into a dome. Hold a steam iron approximately 5–10 cm ($2″–4″$) away from the surface and steam the crown and brim thoroughly. Use your hands to smooth out the stitches and shape the brim into a perfectly uniform, slightly downward sloping flare. Allow the piece to dry completely before wearing.

Beginner/Intermediate Tips

  • Maintain Consistent Tension: Cotton and raffia yarns have very little natural stretch compared to animal fibers like wool. Keep your tension relaxed but firm; pulling too tightly can strain your hands and make it difficult to insert your hook into previous single crochet rounds.
  • Always Count Stitches: The subtle flare of the sun hat relies heavily on exact math. Missing an increase can warp the silhouette or cause the brim to buckle unevenly. Use your stitch marker religiously and verify your final counts at the end of every round.
  • Seamless Spiral Strategy: When working continuous rounds, it is normal for the start of the round to slowly drift diagonally. Do not panic—this is a natural characteristic of spiral crochet. Simply move your marker to the true first stitch of every new round to stay aligned.

Variations

  • Two-Tone Contrast: Complete the main crown and side sections in a crisp cream or white yarn, then switch to a rich tan or navy blue yarn precisely at Round 47 to make the decorative eyelet mesh border and final edging pop.
  • Extra Wide Drama Brim: If you prefer maximizing your sun defense, continue repeating the established increase progression pattern for an extra 6 to 8 rounds before starting the decorative eyelet mesh rows.
  • Boho Ribbon Weave: The ch-1 open spaces created during Round 47 are perfect for customization. Weave a thin faux-leather cord, a colorful silk scarf, or a matching grosgrain ribbon through the eyelets and tie it into a delicate bow at the back.
  • Raffia Texture: Swap out the sport weight cotton yarn for natural matte raffia fiber using the exact same hook size. This alternative material gives the finished hat a highly structured, rustic, boutique-style appearance.
