Wrap a little one in something soft, whimsical, and completely handmade with this Ocean Blue Starfish Baby Blanket Free Crochet Pattern.

This ocean-inspired blanket combines a five-point starfish silhouette with a soothing gradient that moves from pale seafoam and aqua into deeper ocean blue.

The main blanket is worked as a textured center with five tapered points, then finished with a simple edging. Small raised crochet motifs add gentle starfish-like texture, while an optional hood transforms the blanket into a cozy wrap for supervised cuddles, stroller photos, or nursery use.

It is a beautiful project for baby showers, ocean-themed nurseries, handmade keepsakes, and coastal baby gifts.

Why You’ll Love This Starfish Blanket

This blanket stands out because it is not a standard rectangle.

The five-point silhouette makes it playful and instantly recognizable, while the ocean palette keeps the finished project soft and calming.

It is also easy to customize.

Try:

• Seafoam + aqua + ocean blue
• Cream + dusty blue
• Sage + teal
• Lavender + blue
• Coral + cream
• Pastel rainbow

You can also leave off the hood for a simpler star-shaped baby blanket.

• Approx. 900–1,100 yd worsted-weight yarn total

Finished Size

The sample blanket measures approximately:

36 in / 91 cm from point to opposite edge

The exact size depends on your yarn, hook, tension, and how many rows you add to each point.

For a larger toddler blanket, simply enlarge the center and add more rows to each arm.

Part 1: Crochet the Center Body

Using pale seafoam yarn:

Round 1

Create a magic ring.

Work:

10 sc into MR

Pull closed.

Join with sl st.

Round 2

Work:

2 sc in each stitch around

You now have:

20 sts

Round 3

Repeat:

sc, inc

around.

Round 4

Repeat:

2 sc, inc

around.

Continue increasing evenly until the center measures approximately:

10–12 in / 25–30 cm across

The center should lie completely flat.

Do not worry if it looks more circular at this stage. The star shape appears once the five points are added.

Mark Five Sections

Place 5 stitch markers evenly around the outer edge.

These markers divide the blanket into five equal sections.

Each section becomes one starfish point.

Part 2: Crochet the First Starfish Point

Join light aqua yarn at the first marked section.

Work only across that section in rows.

Row 1

Sc evenly across the section.

Ch 1, turn.

Row 2

Dec at the beginning.

Sc across until 2 sts remain.

Dec.

Ch 1, turn.

Row 3

Sc across.

Ch 1, turn.

Continue alternating:

• One decrease row
• One straight row

until approximately 4–6 stitches remain.

Shape the Point

For the final rows:

Dec at both edges every row until 1–2 stitches remain.

Fasten off.

The result should be a long, softly tapered starfish arm.

Do not make the final tip too sharp.

A slightly rounded point looks softer for a baby blanket.

Repeat for All Five Points

Repeat the same process in each marked section.

Try to keep every point the same number of rows.

Use stitch markers or write down your row count for consistency.

Part 3: Create the Ocean Gradient

For the sample palette:

Upper Section

Pale seafoam

Upper-Middle

Light aqua

Middle

Muted teal

Lower Sections

Deep ocean blue

You can change colors gradually while working the points.

For a softer transition, alternate colors for one or two rows before fully switching.

Example:

1 row old color
1 row new color
then continue completely in the new color.

Ombre Yarn Option

You can also use one long-gradient cake yarn.

This eliminates most color changes and creates a natural ocean fade automatically.

Part 4: Add the Outer Edging

Join yarn at any point.

Ch 1.

Work 1 sc evenly around the entire blanket.

At the outer tips:

Work:

sc, ch 1, sc

into the point.

Along inside corners between two star arms:

Work one decrease if necessary.

This helps the blanket lie flat without bunching.

Optional Second Border Round

For a more finished edge:

Work one additional round of:

hdc in each stitch

At the point tips:

hdc, ch 1, hdc

Fasten off.

Weave in all ends.

Keep the Edging Soft

Avoid crocheting the border too tightly.

If the blanket begins to curl inward, switch to a larger hook for the edging or add occasional increases.

Part 5: Add the Raised Starfish Texture

The small raised motifs are optional.

They create the pretty dimensional texture visible across the blanket.

Mini Puff Motif

Join matching yarn at the desired location.

Into one stitch work:

[yo, insert hook, pull up loop] 3 times

Yo and pull through all loops.

Ch 1 to secure.

Create several puff stitches arranged close together to form a tiny flower/star shape.

Fasten off securely at the back.

Placement

Add the motifs sparingly.

Good locations include:

• Along the center of each star arm
• Near the color transitions
• Around the central body

Avoid making the entire surface heavily textured.

A few motifs create more visual impact.

Flat Alternative

For a flatter baby blanket, skip the raised motifs or embroider simple stars instead.

Part 6: Crochet the Optional Hood

The hood can be attached at the top star point.

Using pale mint yarn:

Ch enough stitches to measure approximately:

9–10 in / 23–25 cm

Row 1

Hdc across.

Ch 1, turn.

Row 2

Hdc across.

Continue until the rectangle measures approximately:

9 × 10 in / 23 × 25 cm

Shape the Hood

Fold the rectangle in half.

Seam one short edge to create the back of the hood.

Turn right side out.

You now have a simple baby hood.

Add the Ribbed Face Edge

Join yarn along the hood opening.

Work:

hdc BLO

around the opening for approximately 3–4 rounds.

This creates a soft ribbed frame.

Attach the Hood

Center the hood on the upper point of the blanket.

Pin it carefully.

Sew the lower back edge of the hood securely to the blanket.

Use matching yarn and small stitches.

The hood should sit flat when the blanket is spread out.

Optional Front Flaps

For a wrap-style look, extend the two upper side sections slightly.

You can overlap them across the baby's torso during supervised use.

For infant safety, avoid loose cords, dangling ties, or detachable decorations.

Button-Free Version

The reference style may suggest a buttoned wrap, but for a baby blanket I recommend keeping the design button-free whenever possible.

If decorative buttons are used for photography or gifting, make sure they are securely attached and remove them before unsupervised use.

Make a Smaller Newborn Wrap

Use DK yarn and a 4–4.5 mm hook.

Make a smaller center and reduce the number of rows in each point.

Aim for approximately:

28–30 in / 71–76 cm

across.

Make a Larger Toddler Blanket

Increase the center diameter.

Then add more rows to every point before beginning the final decreases.

Aim for:

42–46 in / 107–117 cm

across.

Make It Without a Hood

Skip the hood completely.

The blanket becomes a simple decorative starfish-shaped baby blanket.

This version is especially useful for:

• Floor play
• Stroller use
• Nursery décor
• Baby shower gifts

Make a Matching Ocean Nursery Set

Use the same yarn palette for:

• Baby hat
• Booties
• Crochet whale
• Starfish plush
• Sea-shell garland
• Baby cardigan

The coordinated colors create a beautiful handmade ocean-themed gift set.

Baby Shower Gift Idea

Fold the starfish blanket so the points overlap toward the center.

Tie loosely with a wide fabric ribbon.

Add a handmade gift tag and matching baby hat.

The unusual star shape makes the gift especially memorable.

Tips for a Professional Finish

Keep all five sections equal.

Count the rows in every point.

Block the blanket after finishing.

Use gradual decreases for smooth star arms.

Change colors at the same approximate position on each point.

Keep raised motifs small.

Do not overcrowd the blanket with texture.

Weave in every yarn tail securely.

Use washable baby-friendly yarn.

Blocking the Starfish Blanket

Lightly dampen the blanket.

Lay it flat on blocking mats.

Stretch each of the five points evenly.

Measure from the center to each tip.

Adjust until all five arms are approximately equal.

Allow the blanket to dry completely.

Blocking dramatically improves the final starfish shape.

Baby Safety Notes

For babies:

• Avoid loose buttons, beads, and detachable decorations
• Do not add long cords or tassels
• Secure all yarn ends
• Use breathable, baby-safe yarn
• Keep the baby's face uncovered
• Do not use loose blankets for unattended infant sleep

Use the hooded or wrap-style version only during awake, supervised use.
