Introduction

This Seafoam Bucket Brim Crochet Hat is a fun, wearable project for anyone who has mastered the basics and wants to make something with real streetwear style. The hat pairs a soft seafoam green with bold deep-blue stripes, giving it a fresh, coastal-meets-city look that works with almost any outfit. It's worked entirely in single crochet, so the fabric is dense, cozy, and holds its shape beautifully. The cylindrical crown and flat circular brim make it a satisfying, quick-to-read pattern that you'll want to make in every color combo.

Materials Needed

  • Yarn: DK weight (3), acrylic or cotton blend. Color A (seafoam): 100 yds. Color B (deep blue): 80 yds.
  • Hook: 4.0 mm (US G/6)
  • Notions: Stitch marker, tapestry needle, scissors, measuring tape
  • Finished size: Circumference 22 inches, height 7 inches (crown 5 inches, brim 2 inches)

Abbreviations

  • MR: Magic ring — an adjustable loop used to start working in the round.
  • sc: Single crochet — insert hook, yarn over, pull up a loop, yarn over, pull through both loops.
  • inc: Increase — work 2 single crochet stitches into the same stitch.
  • sts: Stitches.
  • rnd(s): Round(s) — one complete circle of stitches worked in the round.

Gauge

18 sts x 20 rnds = 4 inches in single crochet. To check, crochet a small swatch in the round or flat and measure a 4-inch section; adjust your hook size if needed to match.

Tips Before You Start

  • Use a stitch marker at the start of each round so you never lose your place in the continuous spiral.
  • Keep your tension even — single crochet in the round can pull tight, so relax your grip for a smooth, flat brim.
  • Change colors on the last yarn-over of the final stitch of a round for a clean stripe transition.
  • The brim increases quickly; count your stitches after each increase round to keep the circle flat and even.

Assembly and Finishing

This hat is worked in one continuous piece, so there is no seaming required. Weave in all yarn ends securely on the inside of the hat, especially at each color change. Block lightly by misting with water and shaping the crown and brim flat; let dry completely to help the brim hold its circular shape.

Pro Tips and Variations

  • Swap the stripe colors for a two-tone look, or work the brim in a contrasting shade for extra pop.
  • Add a round of slip stitch or reverse single crochet around the brim edge for a firmer, more defined finish.
  • For a slouchier fit, add a few extra straight rounds to the crown before starting the brim.
