🧶 Pattern Instructions

💡 Tip: Count your chain in groups of 10 and place markers. The ripple pattern requires an exact stitch count for symmetry.
  1. Step 1
    Ch 121. (121 ch)
Row counter:
💡 Tip: Mark the peak and valley stitches with stitch markers to track the ripple progression. This prevents unraveling of the wave pattern mid-blanket.
  1. Row 1
    Sc in 2nd ch from hook and in each ch across. (120 sc)
  2. Row 2
    Ch 1, turn. Sc in each sc across. (120 sc)
  3. Row 3
    Ch 1, turn. *Sc in next 3 sts, 3 sc in next st (peak), sc in next 3 sts, sc dec over next 2 sts (valley)*. Repeat from * to * 10 times. Sc in final st. (120 sc)
  4. Rows 4-40
    Ch 1, turn. Repeat Row 3 pattern (maintaining peak and valley alignment). Each repeat creates one full ripple cycle.
Row counter:
💡 Tip: The scalloped border is worked in place by picking up stitches from the blanket edges. Ensure even spacing by dividing each edge into thirds before starting scallops.
  1. Row 41 (Top Edge Scallops)
    Ch 1, turn. Sc in first st. *Sk 2 sts, 5 dc in next st (scallop), sk 2 sts, sc in next st*. Repeat from * to * across to last st. (40 scallops + 2 edge sc = 202 sts total)
  2. Right Side Scallops
    Ch 1, turn work 90°. Sc in side of each row down the right edge (40 rows). Sc in corner st. (41 sc)
  3. Bottom Edge Scallops
    Ch 1, turn work 90°. Sc in first ch of foundation row. *Sk 2 sts, 5 dc in next st (scallop), sk 2 sts, sc in next st*. Repeat from * to * across. (40 scallops)
  4. Left Side Scallops
    Ch 1, turn work 90°. Sc in side of each row up the left edge (40 rows). Sl st in first sc of top edge to join. (41 sc)
Row counter:

✂️ Finishing

After completing all four sides of the scalloped border, fasten off and weave in all ends with a yarn needle. Gently block the blanket by laying it flat on a clean, dry surface (or blocking board). Pin the scalloped edges gently to shape them evenly. Allow to dry completely (24 hours) before unpinning. This blocking step is crucial for achieving crisp, even scallops. If desired, use a cool iron on low setting over a damp cloth to set the waves, but do not press directly on the fabric.

📌 Before You Begin

💡

This is an advanced pattern due to the complexity of maintaining ripple symmetry and executing the scalloped border. Experience with wave stitch and shaping is strongly recommended.

💡

Ripple blankets require consistent tension to maintain the wave pattern. Practice the rhythm on a swatch before starting the full blanket.

💡

Use stitch markers to identify the peak and valley stitches of each ripple repeat—this prevents stitch count errors.

💡

The foundation chain is long (121 sts); count carefully and mark every 10 stitches.

🧺 Care Instructions

Machine wash in cool water on a gentle or delicate cycle with mild detergent. Do not use bleach or fabric softener, as these can damage acrylic fibers and dull the scalloped edges. Lay flat to dry or tumble dry on low heat. Do not dry clean. Avoid prolonged direct sunlight to prevent color fading. Gently reshape the scallops by hand while damp if they become compressed during washing.

Questions About This Pattern

Absolutely — just match the weight (Worsted). You'll need about approximately 1100 yards, so make sure your substitute has enough meterage. Acrylic is budget-friendly and machine-washable; wool gives better stitch definition and drape.
This pattern uses techniques that require precision and experience. Expect stitches like ch, sc, hdc, dc and potentially complex shaping. If you're newer to crochet, try a few intermediate patterns first to build confidence with stitch counts and tension before tackling this one.
Find the stitch repeat in the pattern (usually mentioned in the foundation chain section) and add or remove multiples of that number. Keep in mind: with Worsted yarn, every extra inch of width across a blanket adds meaningful yardage — double the size means roughly 4× the yarn. For a baby blanket, halving the dimensions works well as a starting point.
For this pattern, gauge is "16 sc x 10 rows = 4 inches in single crochet". For decorative or non-fitted items it's less critical, but matching gauge ensures you use the right amount of yarn and get the proportions the pattern intends. If your swatch is too small (too many stitches/inch), go up a hook size. Too large — go down.
Machine wash in cool water on a gentle or delicate cycle with mild detergent. Do not use bleach or fabric softener, as these can damage acrylic fibers and dull the scalloped edges. Lay flat to dry or tumble dry on low heat. Do not dry clean. Avoid prolonged direct sunlight to prevent color fading. Gently reshape the scallops by hand while damp if they become compressed during washing. A general rule: when unsure about the yarn, hand wash in cool water with a drop of gentle detergent, squeeze (don't wring), and block flat to dry. This is safe for almost every fiber.
Each section builds on the last, so yes — follow them in order. That said, some finishing sections (like embellishments or optional edging) can be skipped if you prefer a simpler look. Read through all sections before starting so you understand how the pieces fit together and can plan your yarn usage across sections.
