Materials Needed

Before you begin, gather the following materials to ensure a smooth knitting experience. All items are readily available at your local yarn shop or online.

• Yarn: Worsted weight (#4) cotton or cotton-blend yarn in three shades:
  • Light Sky Blue (Color A) – 400 yards
  • Ocean Blue (Color B) – 400 yards
  • Deep Navy (Color C) – 400 yards
  Total: Approximately 1200 yards.
• Needles: US Size 8 (5.0 mm) knitting needles, or size needed to obtain gauge.
• Notions: Tapestry needle for weaving in ends, stitch markers (optional but helpful).

Gauge

18 stitches and 24 rows = 4 inches in stockinette stitch. For the wave pattern, 1 repeat (16 stitches + 2 edge stitches) = 4.5 inches wide and 12 rows = 3 inches tall. Always knit a swatch to ensure your gauge matches for the correct finished size.

Step-by-Step Instructions

This pattern is worked flat in rows. The wave pattern is created by alternating yarn overs (increases) and decreases (K2tog, SSK) over a multiple of 16 stitches plus 2 edge stitches. Follow the instructions carefully, and you'll have a beautiful blanket in no time.

Finished Size

Approximately 30 inches wide by 36 inches long (perfect for a baby blanket).

Pattern Notes

• The blanket is worked flat in rows. The wave pattern is created by alternating increases (YO) and decreases (K2tog, SSK) over a multiple of 16 stitches plus 2 edge stitches.
• Use a slip knot edge stitch on each side for a neat finish: always slip the first stitch of each row purlwise with yarn in back, and knit the last stitch.
• Change colors according to the stripe sequence below. Carry yarn up the side when changing colors every few rows to minimize ends.

Stripe Sequence

• Work 12 rows in Color A (Light Sky Blue)
• Work 12 rows in Color B (Ocean Blue)
• Work 12 rows in Color C (Deep Navy)
• Repeat this sequence throughout the blanket, ending with Color A after the final repeat.
