Tropical Octopus Baby Blanket Free Crochet Pattern

I wanted to create a baby blanket that would be more than just something cozy to wrap around a little one. I had this vision of bringing together ocean friends and tropical vibes in a way that felt playful but still soft and cuddly. The coral and turquoise octopus duo came first, and then I built the whole garden of flowers, leaves, and shells around them. I experimented with different appliqué placements until everything felt balanced and joyful. I am SO pleased with how it turned out, and I cannot wait for you to make one too!

About This Tropical Octopus Baby Blanket Crochet Pattern

This adorable baby blanket combines a simple textured base with colorful three-dimensional appliqués that bring an underwater garden to life. The cream background provides the perfect canvas for the cheerful octopus friends, vibrant tropical flowers, detailed fern leaves, and delicate seashells scattered across the surface.

The blanket measures approximately 30 inches by 30 inches, making it an ideal size for a stroller blanket, tummy time mat, or nursery decoration. The scalloped border in soft coral frames everything beautifully and adds a polished finished look.

Skill level: Intermediate. You should be comfortable with basic stitches and willing to try appliqué work. If you have never made amigurumi style pieces before, do not worry. I will walk you through each element step by step.

Materials You Will Need

Yarn:

– Cream or off-white for the base blanket, approximately 800 yards

– Coral pink for the main octopus and border, approximately 200 yards

– Turquoise or aqua blue for the second octopus, approximately 100 yards

– Lime green for leaves, approximately 150 yards

– Hot pink for flowers, approximately 50 yards

– Golden yellow and orange for flower centers, approximately 30 yards each

– Peach and cream for seashells, approximately 30 yards each

– Small amounts of black for facial features

I recommend a soft acrylic or cotton blend that will hold up to washing. Baby blankets need to be machine washable, so save your luxury fibers for another project.

Hook:

Notions:

Gauge

With 5.0mm hook and worsted weight yarn:

14 stitches and 16 rows = 4 inches in single crochet

Always check your gauge before starting. If your blanket is coming out too small, go up a hook size. Too large? Go down a hook size.

Abbreviations and Stitch Definitions

Let me walk you through every stitch we will use. Even if you know these already, a quick refresher never hurts.

Chain (ch): The foundation stitch. Yarn over, pull through the loop on your hook. This creates the base for most crochet projects.

Single crochet (sc): Insert hook into stitch, yarn over and pull up a loop (two loops on hook), yarn over and pull through both loops. This creates a short, dense stitch.

Half double crochet (hdc): Yarn over, insert hook into stitch, yarn over and pull up a loop (three loops on hook), yarn over and pull through all three loops. Slightly taller than single crochet with a nice drape.

Double crochet (dc): Yarn over, insert hook into stitch, yarn over and pull up a loop, yarn over and pull through two loops, yarn over and pull through remaining two loops. Creates a taller stitch with more openness.

Slip stitch (sl st): Insert hook into stitch, yarn over and pull through both the stitch and the loop on your hook. Used for joining and moving across stitches invisibly.

Magic ring (MR): An adjustable loop that allows you to pull the center closed tightly. Perfect for amigurumi and circular motifs.

Increase (inc): Work two stitches into the same stitch, adding one stitch to your count.

Decrease (dec): Work two stitches together as one, reducing your stitch count.

Blanket Base Pattern

The base of this tropical octopus baby blanket uses a simple moss stitch variation that creates beautiful texture while remaining flat and cozy.

Foundation

With cream yarn and 5.0mm hook:

Row 1: Ch 107. Sc in second ch from hook and in each ch across. (106 sc)

Row 2: Ch 1, turn. Sc in first st, *ch 1, skip 1 st, sc in next st* across. (53 sc, 53 ch-1 spaces)

Row 3: Ch 1, turn. Sc in first sc, *sc in ch-1 space, ch 1, skip sc* across, ending with sc in last sc. (54 sc, 52 ch-1 spaces)

Row 4: Ch 1, turn. Sc in first sc, *ch 1, skip sc, sc in ch-1 space* across, ending with sc in last sc. (54 sc, 52 ch-1 spaces)

Repeat Rows 3 and 4 until blanket measures approximately 28 inches from beginning, ending on an even row.

Final Row: Ch 1, turn. Sc in each st and ch-1 space across. (106 sc)

Fasten off and weave in ends.

Scalloped Border

The coral scalloped border gives this blanket such a cheerful finished edge. Take your time on the corners.

Join coral yarn in any corner with a sl st.

Round 1: Ch 1, sc evenly around entire blanket, working 3 sc in each corner. Join with sl st to first sc.

Round 2: Ch 1, sc in same st, *skip 2 sts, 5 dc in next st (shell made), skip 2 sts, sc in next st* around, adjusting as needed at corners to keep the edge flat. Join with sl st to first sc.

Fasten off and weave in ends.

If your border is ruffling, you are working too many stitches. If it is pulling in, add more stitches on Round 1.

Coral Octopus Appliqué

This sweet octopus with the happy closed eyes is the star of the show. We will make the head and tentacles separately, then join them together.

Octopus Head

With coral yarn and 4.0mm hook, using the magic ring:

Round 1: 6 sc in MR, pull tight. (6 sc)

Round 2: Inc in each st around. (12 sc)

Round 3: *Sc in next st, inc in next st* around. (18 sc)

Round 4: *Sc in next 2 sts, inc in next st* around. (24 sc)

Round 5: *Sc in next 3 sts, inc in next st* around. (30 sc)

Rounds 6 through 10: Sc in each st around. (30 sc)

Round 11: *Sc in next 3 sts, dec* around. (24 sc)

Round 12: *Sc in next 2 sts, dec* around. (18 sc)

Stuff head firmly with fiberfill.

Round 13: *Sc in next st, dec* around. (12 sc)

Round 14: Dec around. (6 sc)

Fasten off, leaving a long tail. Close remaining hole and set aside.

Octopus Tentacles (Make 8)

With coral yarn and 4.0mm hook:

Ch 25. Starting in second ch from hook: *sc, hdc, dc, dc* repeat this pattern along the chain, curling naturally as you go. The varying heights create the spiral effect.

Fasten off, leaving a tail for attaching.

Attach all 8 tentacles evenly around the bottom of the octopus head, spreading them in a natural arrangement.

Facial Features

Using black yarn, embroider two curved lines for happy closed eyes. Each eye should be about 4 stitches wide, with a gentle downward curve. Add small rosy cheeks using pink yarn if desired.

Turquoise Octopus Appliqué

Make this octopus exactly like the coral one, substituting turquoise yarn. Give this one open eyes by embroidering small circles or using black safety eyes before stuffing (just make sure they are securely attached for baby safety).

Tropical Flower Appliqués (Make 6)

These cheerful flowers add so much life to the blanket. Mix up your center colors for variety.

With yellow or orange yarn and 4.0mm hook:

Round 1: 6 sc in MR. (6 sc)

Round 2: Inc in each st around. Join with sl st. (12 sc)

Fasten off yellow. Join hot pink or coral in any st.

Round 3: *Ch 3, 2 dc in same st, ch 3, sl st in same st (petal made), sl st in next st* around. (6 petals)

Fasten off and weave in ends.

Fern Leaf Appliqués (Make 8)

These tropical leaves add wonderful movement to the design. They look complicated but work up quickly once you get the rhythm.

With lime green yarn and 4.0mm hook:

Ch 15 for the center stem.

Working along one side of the chain: *sl st, ch 5, sl st in second ch from hook, sc, hdc, dc, sl st in next ch of stem* repeat, creating 6 leaf points along one side.

Ch 3 at the top for the leaf tip.

Working down the other side of the stem: create 6 matching leaf points.

Fasten off, leaving a tail for attaching.

Seashell Appliqués (Make 6)

With peach or cream yarn and 4.0mm hook:

Row 1: Ch 4. Dc in fourth ch from hook. (2 dc counting turning ch)

Row 2: Ch 3, turn. Dc in same st, 2 dc in next st. (4 dc)

Row 3: Ch 3, turn. Dc in same st, dc in next 2 sts, 2 dc in last st. (6 dc)

Row 4: Ch 1, turn. Sc across, creating ridged texture.

Fasten off and weave in ends. The natural fan shape mimics a scallop shell perfectly.

Small Dot Embellishments (Make 10 to 12)

These tiny pops of color fill in empty spaces beautifully.

With turquoise, coral, or cream yarn:

6 sc in MR. Pull tight and fasten off, leaving a tail for attaching.

Assembly and Finishing

Now comes the fun part! Lay your blanket flat and arrange all your appliqués before sewing anything down.

Place both octopuses slightly below center, with the coral one on the left and turquoise on the right. Fan their tentacles naturally, letting some overlap.

Position the larger tropical flowers in the corners and scattered between the octopuses. Add fern leaves in each corner, angling them outward like they are growing from the edges.

Tuck seashells throughout, clustering a few near the octopuses. Scatter the small dots in any empty spaces.

Take a photo before you start sewing. Trust me on this one!

Using your yarn needle and matching yarn colors, whipstitch each appliqué securely to the blanket base. For the stuffed octopus bodies, sew all the way around the bottom edge where it meets the blanket.

Care Instructions

Machine wash this blanket on a gentle cycle with cold water. Tumble dry on low or lay flat to dry. The appliqués may need some reshaping after washing, simply fluff and arrange the tentacles while damp.

Pattern Customization Ideas

Size adjustments: For a larger blanket, add stitches to your foundation chain in multiples of 2. For each additional 4 inches of width, add approximately 14 chains.

Color variations: Try navy and mint octopuses for a more modern nursery. Swap the coral border for mint green. Use sunset colors like orange, pink, and yellow for the flowers.

Simplify for beginners: If the appliqués feel overwhelming, start with just the two octopuses and add more elements over time.

Gifting This Blanket

This tropical octopus baby blanket makes an unforgettable baby shower gift. The handmade appliqués show the love and time you invested. Consider including a matching octopus rattle or teether to complete the set.

For gifting, I recommend washing and blocking the blanket first so it arrives soft and ready to use.
