Materials Needed

Before you begin, gather the following supplies to ensure a smooth knitting experience:

Yarn

• Worsted weight yarn in 3 shades (approximately 200g total):
  • Seafoam green (approx. 70g)
  • Soft aqua (approx. 70g)
  • Pearl white (approx. 60g)

Pro tip: Choose yarns with a slight sheen or silk blend to enhance the iridescent, sea-glass effect. Brands like Malabrigo Worsted, Cascade 220, or Lion Brand Wool-Ease work beautifully.

Needles

• US 7 (4.5mm) 16-inch circular knitting needle
• US 7 (4.5mm) double-pointed needles (DPNs) for the crown decreases

Notions

• Stitch marker
• Tapestry needle for weaving in ends
• Scissors
• Optional: faux fur pom-pom or decorative sea glass beads

Gauge

• 20 stitches and 28 rows = 4 inches in stockinette stitch (knit every round)

Important: Always knit a gauge swatch before starting. If your gauge is off, adjust your needle size accordingly. A proper gauge ensures the beanie fits comfortably and the decreases align correctly.

Step-by-Step Instructions

This pattern is worked in the round from the brim to the crown. The color changes every 4 rounds create subtle, organic stripes reminiscent of layered sea glass. Follow along carefully, and you'll have a stunning beanie in no time!

Abbreviations

• CO = cast on
• K = knit
• P = purl
• K2tog = knit two stitches together (decrease)
• PM = place marker
• SM = slip marker
• St(s) = stitch(es)
• Rnd(s) = round(s)

Pattern Notes

• Worked in the round from the brim to the crown.
• Use a long-tail cast on for a stretchy, comfortable edge.
• Change colors every 4 rounds to create the layered sea glass effect.
• When changing colors, knit the first stitch of the new color loosely to avoid puckering.

Brim

CO 88 stitches with seafoam green using the long-tail cast on method. Join in the round, being careful not to twist your stitches. PM to mark the beginning of the round.

Rnds 1-8: *K2, P2; repeat from * to end of round. (88 sts)

This ribbed brim provides a snug, stretchy fit that will keep the beanie securely on your head.

Body

Now we begin the color sequence that gives this beanie its magical, ocean-inspired look. Each color is worked for 4 rounds before switching.

Switch to aqua. Work in stockinette stitch (knit every round) for 4 rounds.

Switch to pearl white. Knit 4 rounds.

Switch to seafoam green. Knit 4 rounds.

Repeat this color sequence (aqua, pearl, seafoam) until the piece measures 6 inches from the cast-on edge, ending with a seafoam green section.

Tip: To keep track of your color changes, use a row counter or make a small note each time you switch colors. The organic, slightly irregular stripe effect is part of the charm, so don't worry about perfection!

Crown Decreases

Now we'll shape the crown of the beanie. Continue in the same color sequence, but begin decreasing as follows. The decreases are spaced evenly to create a smooth, rounded taper.

Rnd 1 (aqua): *K9, K2tog; repeat from * to end. (80 sts)

Rnd 2-3 (aqua): Knit all stitches.

Rnd 4 (pearl): *K8, K2tog; repeat from * to end. (72 sts)

Rnd 5-6 (pearl): Knit all stitches.

Rnd 7 (seafoam): *K7, K2tog; repeat from * to end. (64 sts)

Rnd 8-9 (seafoam): Knit all stitches.

Rnd 10 (aqua): *K6, K2tog; repeat from * to end. (56 sts)

Rnd 11-12 (aqua): Knit all stitches.

Rnd 13 (pearl): *K5, K2tog; repeat from * to end. (48 sts)

Rnd 14-15 (pearl): Knit all stitches.

Rnd 16 (seafoam): *K4, K2tog; repeat from * to end. (40 sts)

Rnd 17-18 (seafoam): Knit all stitches.

Rnd 19 (aqua): *K3, K2tog; repeat from * to end. (32 sts)

Rnd 20-21 (aqua): Knit all stitches.

Rnd 22 (pearl): *K2, K2tog; repeat from * to end. (24 sts)

Rnd 23-24 (pearl): Knit all stitches.

Rnd 25 (seafoam): *K1, K2tog; repeat from * to end. (16 sts)

Rnd 26 (seafoam): Knit all stitches.

Rnd 27 (aqua): *K2tog; repeat from * to end. (8 sts)

Transitioning to DPNs: As the stitch count decreases, the circular needle will become too long. Switch to double-pointed needles when you have approximately 40 stitches remaining. Distribute the stitches evenly across 3 or 4 DPNs.

Finishing

Cut yarn, leaving a 10-inch tail. Thread the tail through a tapestry needle and slide it through the remaining 8 stitches. Pull tight to close the crown, then weave in the end securely on the inside of the beanie.

Weave in all loose ends using a tapestry needle. Be sure to weave in ends on the wrong side of the work, following the path of the yarn to keep them invisible.

Optional embellishments: Add a faux fur pom-pom to the crown for extra charm, or attach a small cluster of knitted 'sea glass' beads for a truly unique, ocean-inspired look.

Block gently to shape. Wet block or steam block the beanie to even out the stitches and enhance the drape. Lay flat to dry, shaping the crown as needed.
