The Aurora Borealis Ripple Blanket: A Free Crochet Pattern for a Modern, Textured Baby Blanket

This stunning baby blanket uses a unique ripple stitch pattern and a gradient of cool, modern colors to create a mesmerizing, textured heirloom piece. Perfect for a contemporary nursery, this pattern is surprisingly easy to master and creates a beautifully cozy, drapey fabric. The undulating peaks and valleys mimic the northern lights, making it a truly special gift.

Materials Needed

  • Yarn: Worsted weight (#4) cotton or cotton-acrylic blend yarn in 5 colors: A (Deep Teal), B (Misty Blue), C (Lavender), D (Soft Pink), E (Cream). Approximately 200g of each color.
  • Hook: 5.0 mm (H-8) crochet hook
  • Gauge: 14 stitches and 8 rows of the ripple pattern = 4 inches (10 cm). Exact gauge is not critical, but consistency is important for the ripple effect.
  • Notions: Yarn needle for weaving in ends, scissors, blocking pins (optional).

Step-by-Step Instructions

Notes

  • The blanket is worked in rows. The ripple pattern is created by a combination of increases and decreases.
  • Carry the unused yarn loosely up the side of the work, or cut and rejoin for each color change. A color change is made on the last yarn over of the last stitch of a row.
  • Ch 1 at the beginning of a row does not count as a stitch.
  • sc3tog: Insert hook in next stitch, yarn over, pull up a loop (2 loops on hook). Insert hook in next stitch, yarn over, pull up a loop (3 loops on hook). Insert hook in next stitch, yarn over, pull up a loop (4 loops on hook). Yarn over and pull through all 4 loops on hook. This creates a decrease of 2 stitches.

Foundation Chain

With Color A (Deep Teal), chain 142. This chain should be loose and even. If you tend to chain tightly, use a hook one size larger for the foundation chain only.

Row 1 (Right Side)

Sc in 2nd ch from hook, sc in next 2 ch. *sc3tog over next 3 ch, sc in next 3 ch, (sc, ch 2, sc) in next ch, sc in next 3 ch; repeat from * across to last 6 ch, sc3tog over next 3 ch, sc in next 2 ch, sc in last ch. Turn. (You will have 10 full ripple peaks and valleys).

Row 2

Ch 1, sc in first sc, sc in next 2 sc. *sc3tog over next 3 sc, sc in next 3 sc, (sc, ch 2, sc) in next ch-2 space, sc in next 3 sc; repeat from * across to last 6 sc, sc3tog over next 3 sc, sc in next 2 sc, sc in last sc. Turn.

Repeat Row 2 for the entire blanket

Continue repeating Row 2, changing colors as follows. To change color: On the last yarn over of the last stitch of a row, pull through the new color. Cut the old color, leaving a 6-inch tail to weave in later.

  • Rows 1-10: Color A (Deep Teal)
  • Rows 11-20: Color B (Misty Blue)
  • Rows 21-30: Color C (Lavender)
  • Rows 31-40: Color D (Soft Pink)
  • Rows 41-50: Color E (Cream)
  • Rows 51-60: Color D (Soft Pink)
  • Rows 61-70: Color C (Lavender)
  • Rows 71-80: Color B (Misty Blue)
  • Rows 81-90: Color A (Deep Teal)

Finishing

After completing Row 90, fasten off by cutting the yarn, leaving a 6-inch tail. Pull the tail through the last loop on your hook. Weave in all ends using a yarn needle, being careful to follow the path of the stitches so the ends are invisible.

Block the blanket gently to open up the ripple stitches and even out the edges. To block, soak the blanket in cool water with a small amount of wool wash (if using wool) or mild detergent. Gently squeeze out excess water (do not wring). Lay flat on a towel, roll up to remove more water, then unroll and shape to the desired dimensions. Pin the peaks and valleys if needed. Allow to dry completely.

If desired, add a simple border of single crochet in Color E (Cream) around the entire blanket. Join yarn in any corner ch-2 space. Ch 1, work sc evenly around the blanket, working 3 sc in each corner ch-2 space. Join with a slip stitch to the first sc. Fasten off and weave in ends.
