Tomorrowland Hat in Berroco Lumi – Crochet Pattern Summary

The Tomorrowland Hat is a crocheted hat designed by Mel Kennelly and published by Berroco. This stylish, wearable accessory is worked in the round from the top down, making it a satisfying project for crocheters who enjoy watching a design grow organically from crown to brim. The pattern is available as a downloadable PDF and is rated as an Easy to Intermediate skill level, making it accessible to those who have a comfortable grasp of basic crochet techniques and are ready to refine their in-the-round construction skills.

What Is Being Made

The finished project is a crocheted hat offered in two sizes. The smaller size measures approximately 32 inches (81.5 cm) around the brim and 8½ inches (21.5 cm) high, while the larger size measures approximately 35½ inches (90 cm) around the brim and 9½ inches (24 cm) high. Both sizes share a structured silhouette with a shaped crown, a fitted side panel, and a turned brim that adds a polished, finished edge to the hat.

Construction Techniques

The Tomorrowland Hat is constructed entirely in the round, beginning at the crown and working downward toward the brim — a top-down construction method that allows for easy size adjustments and eliminates the need for seaming. Key construction details include:

• Sliding loop cast-on: The crown begins with a sliding loop (also known as a magic ring), which closes tightly to eliminate any hole at the top of the hat — a hallmark of well-finished crochet hats.
• Joined rounds: Both the crown and the side panel are worked in joined rounds, where each round is closed with a slip stitch and a new chain is used to begin the next round. This creates a neat, structured fabric.
• Turned, joined rounds for the brim: The brim section introduces a variation in technique — rounds are both turned and joined, which creates a slightly different texture and drape, giving the brim its distinctive character and body.
• Incremental crown shaping: The crown is shaped through a series of carefully spaced increase rounds, beginning with 12 half double crochet stitches and expanding systematically through multiple increase rounds to achieve the full circumference of the hat.

Stitches Used

The pattern makes use of a small, focused set of crochet stitches, keeping the construction approachable while still producing a fabric with visual interest and structural integrity:

• Half double crochet (hdc): The primary stitch used throughout the crown and side panel. Half double crochet creates a dense, slightly stretchy fabric with a subtle texture, ideal for a fitted hat. The gauge for this section is 18 stitches and 14 rounds = 4 inches in hdc.
• Single crochet (sc): Used in the brim section, single crochet produces a tighter, firmer fabric that helps the brim hold its shape. The gauge for this section is 20 stitches and 24 rounds = 4 inches in sc.
• Chain stitch (ch): Used at the beginning of each round as a turning or rising chain. Throughout the pattern, a chain-2 counts as a half double crochet.
• Slip stitch (sl st): Used to join each round, maintaining a clean, continuous circular construction.

Materials

The pattern calls for Berroco Lumi, a DK weight yarn from Berroco. The sample shown uses 2 balls of color #8111 Beach Rose. Each ball weighs 50 grams. Berroco Lumi is a thoughtfully crafted yarn well-suited to accessories like hats, offering stitch definition that highlights the clean lines of half double and single crochet construction.

The recommended tool is a size D / 3.25 mm crochet hook, though crocheters are encouraged to adjust hook size as needed to match gauge. As with all Berroco patterns, gauge is measured after blocking, and checking
