What Makes This Coastal Breeze Chevron Throw Blanket Special

This throw achieves its striking modern-coastal look through a carefully engineered chevron ripple stitch pattern that forms sharp, clean peaks and valleys without warping the fabric. By working exclusively in the back loops of the stitches, we create subtle horizontal ridges that catch the soft daylight, adding rich visual dimension to the cotton-blend yarn. The deliberate four-color sequence—moving from deep ocean navy down to sun-bleached sand—mimics a natural shorelinescape, while the finished tasseled edge adds a relaxed, bohemian polish.

Skill Level

• Required Skills:
• Ability to read a written crochet pattern and count rows accurately.
• Proficiency in basic stitches (ch, sc, hdc, dc).
• Understanding of working increases and simultaneous decreases to form chevron peaks and valleys.
• Basic finishing techniques for adding fringe or tassels.
• Reassurance Line: If you have mastered the basics of double crochet and can keep a watchful eye on your stitch counts for the first two setup rows, you are entirely ready to tackle this project!

Finished Measurements

• Width: 50 inches (127 cm)
• Length: 60 inches (152 cm) excluding fringe

Materials You Will Need

• Yarn Weight: Worsted weight (#4) cotton-acrylic blend
• Hook Size: US I/9 (5.5 mm) crochet hook
• Additional Tools: Tapestry needle for weaving in ends, sharp scissors, a 6-inch piece of cardboard for making tassels, and measuring tape.

Yarn Suggestions

• Lion Brand Coboo: A brilliant cotton-bamboo blend that offers incredible stitch definition, gorgeous drape, and a soft sheen (Approx. 232 yds / 212 m per 100g skein).
• Bernat Handicrafter Cotton: A classic, durable choice that washes beautifully and holds crisp chevron lines (Approx. 200 yds / 184 m per 100g ball).
• Hobbii Friends Cotton 8/8: A wonderful multi-strand cotton yarn with a rich color palette (Approx. 82 yds / 75 m per 50g ball; adjust skein count accordingly).
• Yarn to Avoid: Avoid fuzzy novelty yarns (like eyelash yarn or heavy mohair) or ultra-stretchy acrylics. They obscure the stitch definition, making it difficult to spot your chevron peaks and valleys, and lose the crisp architectural lines characteristic of this design.

Gauge

• 1 full chevron repeat (one peak to the next valley, measuring approximately 4.5 inches wide) and 7 rows in pattern = 4 x 4 inches (10 x 10 cm) using a 5.5 mm hook.
• Note: Be sure to check your gauge by making a swatch before starting your blanket to ensure you do not run short on yarn.

Pattern Instructions

Section 1: Foundation and Setup

The chevron pattern is built on a multiple of 14 stitches plus 3 for the turning chain.

With Color 1 (Deep Ocean Navy), ch 171.
– Row 1 (RS): Working in blo, 2 dc in 4th ch from hook (skipped 3 chs count as first dc and skipped space), dc in next 5 chs, dc3tog over next 3 chs, dc in next 5 chs, 2 dc in next ch, 2 dc in next ch; rep from * across until 2 chs remain, working last 2 dc in final ch. Turn. (11 chevron ripples; 168 sts)
– Row 2 (WS): Ch 3 (counts as first dc here and throughout), working in blo, dc in same st, dc in next 5 sts, dc3tog over next 3 sts, dc in next 5 sts, 2 dc in next st, 2 dc in next st; rep from * across, ending with 2 dc in top of turning ch. Turn. (168 sts)

Section 2: Color Blocking and Body Rows

Continue working in pattern (Row 2 repeat), maintaining the back-loop-only instruction, while following the strict color sequence below. Each color block consists of 14 rows.

• Rows 3–14: Continue with Color 1 (Deep Ocean Navy). At the end of Row 14, change to Color 2. FO Color 1.
• Rows 15–28: With Color 2 (Seafoam Green), repeat Row 2 for 14 rows. At the end of Row 28, change to Color 3. FO Color 2.
• Rows 29–42: With Color 3 (Soft Sand), repeat Row 2 for 14 rows. At the end of Row 42, change to Color 4. FO Color 3.
• Rows 43–56: With Color 4 (Crisp Cotton White), repeat Row 2 for 14 rows. At the end of Row 56, change to Color 1. FO Color 4.

Checkpoint

Stop here and measure your blanket. At Row 56, your blanket should measure approximately 24 inches in length. Verify that your peak and valley counts remain stable at 11 peaks across the width.

• Rows 57–112: Repeat the 4-color block sequence (Colors 1, 2, 3, and 4) one more complete time (14 rows per color).
• Rows 113–126: Work one final color block in Color 1 (Deep Ocean Navy) for 14 rows. FO and weave in all intermediate ends securely.

Section 3: Finishing and Tassels

• Block your blanket lightly with steam if desired to even out the ripples.
• Using a 6-inch piece of cardboard, wrap Color 1 yarn around it 30 times, cut one end to create individual strands, and attach thick 4-inch tassels to every alternate peak and valley along both short ends of the blanket. Trim ends evenly.

Size Customization Tips

• To adjust the width: Chain any multiple of 14 stitches, then add 3 stitches to your initial foundation chain. Each 14-stitch multiple adds exactly one full chevron peak and valley to your blanket width (approximately 4.5 inches / 11.5 cm per repeat).
• To adjust the length: Simply add or subtract complete 14-row color blocks, or adjust the number of rows worked in each individual color block. Be sure to purchase additional yarn if you plan to increase the overall length beyond 60 inches.

Care Instructions

To keep your coastal throw looking pristine, machine wash on a gentle cycle in cold water with mild detergent. Lay flat to dry on a clean surface or block gently while damp to preserve the crisp chevron geometry. Do not bleach or tumble dry on high heat.
