Size and gauge
The instructions make a rectangle with 100 stitches across and 128 rows high, before the border. A sample gauge of 14 stitches and 16 rows per 4 in (10 cm) gives a body about 28.6 × 32 in (73 × 81 cm). Two edging rounds add a little to each side.
This gauge is an illustration, not a measured test sample. Your finished size depends on your yarn, hook, and tension. Measure a swatch before relying on the stated size.
Make a gauge swatch first. Chain 22. Work Row 1 and Rows 2–16 exactly as shown below, making 20 stitches per row. Measure the center, not the edges. If the fabric feels stiff, try a larger hook.
For a different width, multiply your desired body width in inches by your measured stitches per inch. Round to a whole stitch and add two chains for the foundation. You can use any stitch count. For a different length, add or remove complete eight-row repeats.
What you need
- Medium-weight (4) yarn that feels soft, washes well, and does not shed easily. Choose four colors: A = Cloud cream, B = Fog gray, C = Sea blue, D = Sea glass.
- 5.5 mm (US I-9) crochet hook, or the size needed for a soft, even fabric.
- Two stitch markers, scissors, a yarn needle, and a measuring tape.
- Optional: a kitchen scale for planning yarn quantities.
Yarn brands and fiber blends vary. Check the care label before making a baby gift. A smooth acrylic or cotton blend can make the rows easier to see.
Estimate how much yarn to buy
Make a swatch that is 20 stitches wide and 16 rows tall, using the same stitch repeat. Weigh it in grams. Multiply its weight by 40 to estimate the blanket body, then allow about 15% extra for the border, tails, and differences in tension.
For example, a hypothetical 12 g swatch gives 12 × 40 = 480 g for the body. Adding 15% gives about 552 g total. This is a planning calculation, not a tested yarn requirement.
For the striped body, the approximate row shares are A 13%, B 34%, C 31%, and D 22%. Reserve extra Cloud cream (A) for the border. Check that all four yarns have similar weight and thickness.
The simple coastal texture
Most rows use half double crochet (hdc). Every eighth row uses single crochet in the back loop only (sc BLO). That short row leaves a quiet ridge, like a line of foam along the shore.
US crochet abbreviations (tap to open)
- ch: Chain
- hdc: Half double crochet
- sc: Single crochet
- BLO: Back loop only
- sl st: Slip stitch
- Half double crochet: yarn over, insert hook, pull up a loop, yarn over, and pull through all three loops.
- Single crochet: insert hook, pull up a loop, yarn over, and pull through both loops.
- Back loop only: insert the hook under the loop farthest from you at the top of the stitch.
- Turning chain: chain 2 before an hdc row, or chain 1 before an sc row. Turning chains do not count as stitches.

Place a stitch marker in the first and last stitch of a row. Move the markers up as you work, especially after the shorter ridge rows.
Free Cloudy Coast baby blanket pattern
For the Cloudy Coast baby blanket pattern, use US crochet terms. Start with Sea blue (C). Each row has exactly 100 stitches. Turn after every row, and do not count turning chains as stitches.
Foundation and Row 1. With C, chain 102. Work 1 hdc in the third chain from your hook, then 1 hdc in each remaining chain. Turn. (100 hdc)
Rows 2–7. Chain 2, which does not count as a stitch. Work 1 hdc in each of the 100 stitches. Turn after each row. (100 hdc per row)
Row 8: the ridge. Chain 1, which does not count as a stitch. Work 1 sc in the back loop of each stitch across. Turn. (100 sc BLO)
Rows 9–15. Chain 2. Work 1 hdc in both loops of every stitch across. Turn after each row. (100 hdc per row)
Row 16, then repeat. Chain 1. Work 1 sc BLO in each stitch. Turn. (100 sc BLO) Repeat the eight-row texture: seven hdc rows, then one sc BLO row. Continue through Row 128.
The color-row guide
Follow the color changes below while keeping the same eight-row stitch rhythm. The slim cream bands break up the larger sea and fog sections.
| Rows | Color | Number of rows |
|---|---|---|
| 1–12 | C · Sea blue | 12 |
| 13–16 | A · Cloud cream | 4 |
| 17–32 | B · Fog gray | 16 |
| 33–44 | C · Sea blue | 12 |
| 45–48 | A · Cloud cream | 4 |
| 49–64 | D · Sea glass | 16 |
| 65–80 | B · Fog gray | 16 |
| 81–84 | A · Cloud cream | 4 |
| 85–100 | C · Sea blue | 16 |
| 101–112 | D · Sea glass | 12 |
| 113–116 | A · Cloud cream | 4 |
| 117–128 | B · Fog gray | 12 |

To switch colors, stop before the final yarn-over of the last stitch in the current row. Complete that stitch with the new color. Then make the turning chain in the new shade. Leave tails long enough to weave in securely.
Cut the old color at each band, unless you have an established tidy way to carry it without creating loose floats. Do not leave loops or hanging strands on a baby item.
Make the border
The border uses Cloud cream (A) and single crochet. It runs all the way around the blanket without fringe or dangling ties.
Border round 1. With A, join in a top corner stitch at the edge of Row 128. Work 3 sc in that corner stitch. Work 1 sc in each of the next 98 top-edge stitches. Work 3 sc in the other top corner. Down the side, work 1 sc in each interior row end from Row 2 through Row 127, skipping the end of each ridge row (Rows 8, 16, 24, and so on through 120). You now have 111 side stitches. At the bottom, work 3 sc in the first corner foundation chain, 1 sc in each of the next 98 foundation chains, then 3 sc in the last corner foundation chain. Work 111 side stitches up the other side in the same way. Join to the first sc. (430 sc)
Border round 2. Chain 1. Work 1 sc in each stitch around. In the middle stitch of each three-sc corner group, work 3 sc instead of 1 sc. Join to the first sc. Fasten off and weave in the ends. (438 sc)

The side-pickup plan spaces 111 sc along 126 interior row ends. If the border still waves or pulls in, adjust the pickups evenly for your actual gauge. Both sides should match. The counts above apply only to the exact written pickup plan.
Finish and care
Weave each yarn tail through several stitches, reverse direction, and trim only after the end is secure. Follow the yarn label for washing and drying. Spread the damp blanket flat to shape it, without stretching the edge.
Before giving it to a family, check for loose yarn ends and decorations. This is a supervised-use blanket, not a sleep accessory for an infant.
Fix common problems
| Problem | What to check |
|---|---|
| The blanket narrows | Count 100 stitches at each edge. A turning chain is never a stitch. |
| Ridge row feels tight | Keep the sc BLO stitches loose and try the next hook size up for the ridge if needed. |
| Color changes look stepped | Make the color change in the final pull-through of the previous row. |
| Sides lean or curl | Check the first and last stitches, plus consistent turning chains. |
| Border ripples | Use fewer side pickups, spaced evenly, or a smaller border hook. |
| You might run out of yarn | Weigh your swatch and buy matching dye lots before you begin. |

Common questions
Is this blanket suitable for an absolute beginner?
A beginner who knows single and half double crochet can follow it. Make a small swatch first to practice the back-loop ridge.
Can I crochet it in one color?
Yes. Follow the same 128 rows and skip the color changes. The ridge lines still add texture.
How do I make a larger blanket?
Add stitches to the starting chain and work more complete eight-row repeats. Measure your own gauge before choosing the size.
Can a newborn sleep with this blanket?
No. Keep loose blankets out of an infant sleep space. Use it only during supervised awake time or as a keepsake.
