Materials Needed

Before you begin, gather the following materials. All items are readily available at your local yarn shop or online.

Yarn

• Worsted weight (#4) cotton or cotton-blend yarn – approximately 1,200–1,400 yards total. You'll need 4 colors:
  • Color A (Sunny Yellow): ~300–350 yards
  • Color B (Peach): ~300–350 yards
  • Color C (Soft Coral): ~300–350 yards
  • Color D (Cream): ~300–350 yards (plus extra for the final border)

Needles & Notions

• US Size 8 (5.0 mm) knitting needles – straight or circular (circular recommended for comfort with larger projects)
• Tapestry needle for weaving in ends
• Stitch markers (optional, but helpful for keeping track of pattern repeats)
• Scissors
• Blocking mats and pins (optional, for finishing)

Gauge

18 stitches and 24 rows = 4 inches in stockinette stitch. Always knit a gauge swatch before starting to ensure your finished blanket matches the intended size. If your gauge is off, adjust your needle size accordingly.

Step-by-Step Instructions

Follow these detailed instructions carefully. The pattern is written for a beginner-friendly approach, with clear explanations of all special stitches. Take your time, and don't hesitate to refer back to this guide as you work.

Pattern Overview

• Blanket Size: Approximately 30 inches wide by 36 inches long (adjustable by adding multiples of 12 stitches)
• Stitch Pattern: Multiple of 12 + 2 stitches
• Special Stitches Used:
  • k2tog (knit two together): Insert your right needle into two stitches on the left needle as if to knit, then knit them together. This creates a right-leaning decrease.
  • ssk (slip, slip, knit): Slip two stitches knitwise, one at a time, from the left needle to the right needle. Insert the left needle into the front of these two slipped stitches and knit them together. This creates a left-leaning decrease.
  • yo (yarn over): Bring the yarn to the front of the work, then over the right needle to the back. This creates an increase and a decorative hole.

Cast On

With Color A (Sunny Yellow), cast on 122 stitches. This gives you 10 full repeats of the 12-stitch pattern, plus 2 edge stitches (one at each end). If you prefer a wider or narrower blanket, add or subtract multiples of 12 stitches (e.g., 110 stitches for 9 repeats, 134 stitches for 11 repeats).

Rows 1–4: Garter Stitch Border

Knit every stitch across all 4 rows. This creates a neat, non-curling border at the bottom of your blanket. Remember to knit the edge stitches on every row throughout the entire pattern—they form a clean selvedge edge.

Begin the Chevron Pattern

Row 5 (Right Side): With Color A, knit 1 (edge stitch), then repeat the following sequence across the row until 1 stitch remains: *k6, yo, k1, yo, k6, ssk, k2tog*. After the last repeat, knit the final edge stitch.

Row 6 (Wrong Side): Purl all stitches across the row.

Repeat Rows 5 and 6 for 10 more rows (i.e., work a total of 12 rows of Color A, including the initial garter border rows). After Row 16, you will have completed the first color block.

Color Block Sequence

Now you'll switch colors following this sequence. Each color block consists of 12 rows total (6 repeats of Rows 5 and 6).

Switch to Color B (Peach):

• Rows 17–28: Repeat Rows 5 and 6 with Color B. Start Row 17 on the right side, knitting 1 edge stitch, then following the chevron pattern across.

Switch to Color C (Soft Coral):

• Rows 29–40: Repeat Rows 5 and 6 with Color C.

Switch to Color D (Cream):

• Rows 41–52: Repeat Rows 5 and 6 with Color D.

Continue the Pattern

Repeat the entire color sequence (A, B, C, D) until the blanket measures approximately 34 inches from the cast-on edge, ending with a complete color block. To ensure symmetry, finish with a full 12-row block of Color D if possible. If you need to adjust, you can end with any complete color block—just make sure the final border matches.

Final Border

With Color D (Cream), knit 4 rows of garter stitch (knit every stitch across each row). This mirrors the bottom border and gives the blanket a polished, finished look.

Bind Off

Bind off all stitches loosely in knit. To avoid a tight edge that pulls the blanket out of shape, use a larger needle for binding off if needed, or bind off with a loose tension. A simple knit bind-off works beautifully: knit the first stitch, knit the second, then pass the first stitch over the second and off the needle. Continue across the row until one stitch remains, then cut the yarn and pull it through the last loop.

Finishing Touches

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

Blocking: Blocking is essential for this pattern to open up the chevron ripples and even out the edges. Soak the blanket in lukewarm water with a gentle wool wash for 15–20 minutes. Gently squeeze out excess water (never wring or twist). Lay the blanket flat on blocking mats, gently stretching it to the correct dimensions (30" x 36"). Pin the edges, especially the points of the chevrons, to accentuate the ripple pattern. Allow to dry completely before removing pins.

Tips for Success

• Count your stitches regularly. The yo increases and k2tog/ssk decreases should keep the stitch count consistent at 122 stitches, but it's easy to accidentally drop or add a stitch. Check after each row if you're unsure.
• Use stitch markers between each 12-stitch repeat to help you keep your place. Place a marker after the first edge stitch, then every 12 stitches, and one before the final edge stitch.
• Keep your tension even. The ripple pattern looks best with consistent tension. If you tend to knit tightly, consider going up a needle size for a softer drape.
• Choose the right yarn. Cotton or cotton-blend yarn is ideal for baby blankets—it's soft, breathable, and machine washable. Avoid wool if the recipient has sensitive skin.

This Sunbeam Ripple Baby Blanket is a joy to knit and a gift that will be cherished. The rhythmic repetition of the chevron pattern is meditative, and watching the colors transition from sunny yellow to cream is deeply satisfying. Whether you're knitting for your own little one or as a heartfelt gift, this blanket is sure to become a beloved heirloom.

Happy knitting!
