Finished pink and white modern mosaic crochet beanie with diamond pattern

Materials

DK or light worsted yarn in two strongly contrasting colors
4 mm crochet hook, or size needed to match gauge
Stitch marker, yarn needle, scissors and measuring tape
Pom-pom or removable pom-pom attachment

Gauge: 18 stitches and 18 rounds measure 10 cm / 4 in when worked in the round.

Construction

The beanie is worked as a spiral cylinder from the crown edge downward. After reaching the required height, close the foundation edge with a yarn needle and attach the pom-pom.

Odd-numbered chart rounds use color A; even-numbered chart rounds use color B. Only one color is active per round.

Fit note: choose the size by actual head circumference rather than age. Matching gauge is essential.

Foundation and setup

With color A, chain 76 (79, 82, 84, 86, 88). Join with a slip stitch to form a ring without twisting.

R1: single crochet around: 76 (79, 82, 84, 86, 88). Change to color B on the final yarn-over of the last stitch. Place a marker in the first stitch and move it up every round. Do not join the spiral rounds.

R2: BLO single crochet around in color B. Change to color A on the final yarn-over.

Diamond chart rounds

From R3, begin each chart round at column 11 (9, 2, 1, 12, 11) for sizes 1–2 years (3–4 years, 5–8 years, 9–12 years, teen, adult).

Work the current chart row around, repeating columns 1–12 and stopping after the last stitch for the chosen size. Alternate colors every round. After chart row 14, return to chart row 3. Continue until the beanie reaches the listed height. Finish on a color-A round.

Finish the lower edge

Slip stitch into the first stitch, or make an invisible finish: cut and pull the yarn through, thread the tail, pass under both loops of the first stitch, then return the needle into the center of the final stitch. Weave in all ends.

Close the crown

With color A and a yarn needle, sew through the foundation round around the entire opening, spacing each pass about 2 cm apart. Pull firmly to close, then secure with several extra stitches. Attach the pom-pom securely.
