Ocean Wave Ripple Crochet Blanket Free Crochet Pattern

This classic ripple blanket uses foundational stitches like the double crochet, paired with strategic increases and decreases to build its signature chevron peaks and valleys. Sized generously as a standard throw, it takes approximately 20 to 25 hours of mindful, rhythmic stitching to complete, making it a deeply satisfying project and a treasured handmade heirloom or housewarming gift.

Easily customize the final width of your blanket by adjusting your starting foundation chain in multiples of the chevron repeat stitch count detailed later in this guide.

What Makes This Ocean Wave Ripple Crochet Blanket Special

The magic of this design lies in the interplay of clean architectural lines and smooth, intentional color transitions. By working entirely in the back loops only (BLO) for the body rows, the pattern creates a subtle, crisp ridged texture that mimics wind-rippled sand beneath shallow waves. The carefully curated palette shifts naturally from deep oceanic depths to seafoam spray, while maintaining absolute structural symmetry across every chevron peak and valley.

Skill Level

• Confident Beginner to Intermediate
• Familiarity with basic crochet stitches (chain, double crochet)
• Comfort with working consistent increases and decreases within a repeating sequence

If you can maintain an even tension and count your stitches across a row, you have all the skills needed to create this stunning coastal blanket.

Finished Measurements

• Width: 50 inches (127 cm)
• Length: 60 inches (152.5 cm)

Materials You Will Need

• Yarn: Worsted weight (Category 4) premium acrylic or wool-blend yarn for easy care and stitch definition.
• Hook: US Size J/10 (6.0 mm) crochet hook
• Notions: Tapestry needle for weaving in ends, scissors, and optional stitch markers to track edge repeats.

Yarn Suggestions

• Lion Brand Heartland (100% Acrylic, 251 yds / 230 m per 5 oz / 142 g skein) – Requires 3 skeins each of Seafoam, Turquoise, Navy, and Ivory.
• Knit Picks Brava Worsted (100% Premium Acrylic, 218 yds / 199 m per 100 g skein) – Requires 4 skeins each of Seafoam, Turquoise, Navy, and Ivory.
• Caron Simply Soft (100% Acrylic, 315 yds / 288 m per 6 oz / 170 g skein) – Requires 3 skeins each of Seafoam, Turquoise, Navy, and Ivory.

Avoid overly fuzzy novelty yarns or unspun roving yarns, as they obscure the crisp chevron stitch definition and make counting ridge repeats difficult.

Gauge

• 1 ripple repeat (from peak to peak) = approximately 5 inches (12.5 cm) wide.
• 7 rows of double crochet ripple pattern = 4 inches (10 cm) tall.
• Always work a gauge swatch before beginning your blanket to ensure your dimensions match the final measurements.

Abbreviations

• ch – chain
• dc – double crochet
• dc3tog – double crochet 3 together (decrease)
• st(s) – stitch(es)
• BLO – back loop only
• RS – right side
• WS – wrong side
• rep – repeat
• yo – yarn over

Special Stitches Explained

1. dc3tog (Double Crochet 3 Together): [Yo, insert hook in next st, yo and pull up loop, yo and pull through 2 loops] 3 times in the designated 3 stitches (or space), yo and pull through all 4 loops on hook. (Counts as a 2-st decrease used at the valley of the ripple).
2. 2-dc increase: Work 2 double crochets into the very same stitch or space. (Used at the peak of the ripple).
3. BLO (Back Loop Only): Work the designated stitch inserting your hook only under the back loop of the stitch from the previous row, leaving the front loop exposed to create the characteristic horizontal ridge.

Pattern Instructions

Section 1: Foundation and Color Sequencing

The blanket is worked in horizontal rows from the bottom up, changing colors every 2 rows to create clean, rhythmic stripes in the following sequence: Color A (Seafoam), Color B (Turquoise), Color C (Navy), Color D (Ivory). Repeat this 8-row color sequence throughout the entire pattern.

The chevron repeat is based on multiples of 14 stitches, plus 3 stitches for the turning chain and edge balance.

Foundation Row: With Color A, ch 171.

Row 1 (RS): Working in the back bumps of the foundation chain:
* Skip first 3 ch (counts as first dc).
* Dc in next 2 ch, [dc3tog over next 3 ch] twice, [dc in next 2 ch, (2-dc in next ch) twice, dc in next 2 ch, dc3tog over next 3 ch, twice]; rep from * to * across until 3 ch remain, work 2 dc in last ch. Turn. (Total: 168 sts).

Section 2: Main Ripple Body

Row 2 (WS): Ch 3 (counts as first dc here and throughout), dc in first st (counts as increase). [Dc in next 2 sts, BLO-dc3tog over next 3 sts twice, dc in next 2 sts, (2-dc in next st) twice]; rep from * to * across, ending with dc in last st (top of turning ch). Turn. (Total: 168 sts).

Note: Continue working all subsequent body rows in the same manner, maintaining the alternating stripe color sequence every 2 rows.

### Checkpoint

At the end of every active row, verify your stitch count equals 168 stitches. Your peaks and valleys should align vertically with the rows below them, forming an unbroken ocean wave pattern across the width of the fabric.

Repeat Row 2 until your blanket reaches a total length of 60 inches (approximately 104 rows total, depending on your personal gauge), ending after a completed 2-row stripe of Color D. Fasten off and weave in all loose ends securely.

Size Customization Tips

To adjust the size of your Ocean Wave Ripple Crochet Blanket:
* To make it wider: Add chains in exact multiples of 14 to your initial foundation chain (e.g., add 14, 28, or 42 chs), adjusting your yarn yardage requirements accordingly. Each 14-chain addition adds approximately 5 inches (12.5 cm) to the final width.
* To make it narrower: Subtract chains in multiples of 14 from the initial foundation chain.
* To make it longer or shorter: Simply work more or fewer total rows in the established color stripe sequence before fastening off.

Care Instructions

To keep your handmade ocean wave blanket looking pristine and feeling soft:
* Machine wash on a gentle, delicate cycle using cool or lukewarm water and mild detergent.
* Tumble dry on low heat or lay flat to dry completely in a well-ventilated area.
* Do not bleach, iron, or dry clean.
