Watch Hill Sun Hat – Crochet Pattern for Women in Tahki Yarns Cotton Classic

The Watch Hill Sun Hat is a stylish, warm-weather crochet hat designed by Mary Lynn Patrick for Tahki Yarns. This easy, beginner-friendly pattern produces a classic sun hat with a structured crown and a wide, floppy brim — perfect for beach days, garden outings, or any sunny occasion. The pattern is available as a downloadable PDF and is worked entirely in one size, with a finished crown circumference of 21 inches (53.5 cm), a crown depth of 6¼ inches (16 cm), and a brim depth of 4 inches (10 cm).

What Is Being Made

This pattern creates a women's sun hat with a shaped, seamless crown that expands outward into a broad, sun-protective brim. The combination of a solid yarn and a twisted, multicolored yarn gives the hat visual texture and a fresh, summery aesthetic. The finished hat is lightweight and breathable, making it an ideal accessory for warm-weather wear.

Yarn and Materials

• Tahki Yarns Cotton Classic – 100% mercerized cotton, 1.75 oz / 50 g per skein, approximately 108 yards / 100 m per skein. Used in color #3001 White (Color A). Two skeins required.
• Tahki Yarns Cotton Classic Twist – 100% mercerized cotton, 1.75 oz / 50 g per skein, approximately 108 yards / 100 m per skein. Used in color #5100 Spring Flowers (Color B). Two skeins required.
• Both yarns are classified as DK weight, making them light enough for comfortable warm-weather wear while still providing excellent stitch definition.
• Mercerized cotton is a particularly popular choice for sun hats because the mercerization process gives the fiber a subtle sheen, increases its strength, and helps the finished fabric hold its shape — all desirable qualities in a structured brim hat.
• A size E-4 (3.5 mm) crochet hook is recommended, or the size needed to achieve gauge.
• A yarn needle is required for finishing.

Gauge

Achieving the correct gauge is important for this pattern, particularly to ensure the hat fits the intended crown circumference. The stated gauge is 19 stitches and 15 rounds = 4 inches / 10 cm in half double crochet (hdc). Crocheters are advised to take time to check gauge before beginning the main body of the hat.

Techniques Used

• Worked in the round – The entire hat is constructed in continuous or joined rounds, beginning at the very top of the crown and working outward and downward. This eliminates the need for seaming and creates a smooth, professional finish.
• Crown shaping with increases – The crown begins with a small foundation ring (chain 4, joined with a slip stitch) and expands through a series of evenly spaced increase rounds. This is a classic crochet hat construction method that produces a flat, circular top that gradually curves into the sides of the hat.
• Joining rounds with slip stitches – Each round is closed with a slip stitch join, keeping the work neat and the round boundaries consistent.
• Brim construction – After the crown reaches the desired circumference, the pattern transitions into the brim section, which adds the signature wide, floppy shape of a sun hat. The brim is typically worked with additional increases to create the outward flare.
• Two-color design – The pattern makes use of both Cotton Classic (Color A, White) and Cotton Classic Twist (Color B, Spring Flowers), likely alternating or combining them to create a striped or color-blocked effect that adds visual interest to the finished hat.

Stitches Used

• Chain stitch (ch) – Used to begin the foundation ring and to create the turning/starting chains at the beginning of each round.
• Slip stitch (sl st) – Used to form
