How to Crochet an Amigurumi Whale: A Complete Step-by-Step Tutorial

If you’ve ever wanted to make the most adorable little stuffed whale imaginable, you’ve come to the right place. This amigurumi whale crochet tutorial will walk you through everything you need — from the yarn and hook you’ll want to grab, to the final assembly that brings your little sea creature to life. Whether you’re a beginner who has just learned the magic ring or an experienced crocheter looking for a fun weekend project, this pattern is approachable, satisfying, and results in something genuinely charming.

Amigurumi is the Japanese art of knitting or crocheting small stuffed animals and figures, and whales — or “ballenitas” as they’re affectionately called in the Spanish-speaking crochet world — are one of the most beloved amigurumi designs out there. Their round bodies, tiny fins, and expressive button eyes make them irresistible to both children and adults. Let’s dive in.

What You’ll Need Before You Start

Getting your materials together before you sit down to crochet will make the whole experience smoother and more enjoyable. Here’s a complete list of everything you’ll need for this amigurumi whale project.

Yarn: You’ll need a medium weight yarn (also labeled as worsted weight or size 4) in your main color for the body. Light blue, dusty teal, navy, and lavender are all popular choices for amigurumi whales, but you can absolutely use any color you love. You’ll also want a small amount of white or cream yarn for the belly, and an even smaller amount of a contrasting color if you want to add cheeks.

Crochet Hook: A 3.5mm or 4mm hook works beautifully with worsted weight yarn for amigurumi. Using a hook that’s slightly smaller than the yarn label recommends creates a tighter stitch, which keeps the stuffing from showing through and gives your whale a firmer, more polished look.

Safety Eyes: Two 10mm or 12mm black safety eyes are ideal. If you’re making this whale for a child under three, skip the safety eyes and embroider the eyes instead using black yarn, as safety eyes can be a choking hazard.

Polyfill Stuffing: Standard polyester fiberfill stuffing works perfectly. You’ll want to stuff the body firmly but not so tightly that the stitches stretch and show gaps.

Yarn Needle: Also called a tapestry needle or darning needle. You’ll use this to sew the pieces together and to weave in your ends.

Stitch Markers: These are helpful for marking the beginning of each round so you don’t lose your place. You can use a small piece of contrasting yarn tied in a loop if you don’t have stitch markers handy.

Scissors: A sharp pair makes clean cuts on your yarn.

Blush or Pink Marker (Optional): A little touch of blush on the cheeks gives your whale an extra dose of sweetness.

Understanding Amigurumi Basics

Before we get into the pattern, let’s go over a few foundational concepts that will help you throughout this tutorial.

Working in Continuous Rounds: Unlike flat crochet, amigurumi is worked in continuous spiral rounds. You don’t join at the end of each round or chain one to begin a new round. You simply keep going. This is why stitch markers are so useful — place one at the beginning of each round and move it up as you go.

The Magic Ring: Also called a magic circle, this is the most common way to begin amigurumi pieces. It allows you to start crocheting in the round with an adjustable, closeable center hole. If you haven’t mastered it yet, there are many video tutorials online that show it clearly, and it only takes a few minutes of practice to get it.

Increases and Decreases: You’ll be shaping your whale’s body by increasing (working two single crochets into the same stitch, abbreviated as “inc”) and decreasing (working two stitches together to become one, abbreviated as “dec” or “sc2tog”).

Abbreviations Used in This Pattern:

MR — Magic Ring
SC — Single Crochet
Inc — Increase (2 SC in the same stitch)
Dec — Decrease (also called invisible decrease: insert hook into the front loops of two consecutive stitches and complete as one SC)
St — Stitch
Sl St — Slip Stitch
Ch — Chain
FO — Fasten Off

Gauge and Finished Size

With a 4mm hook and worsted weight yarn, your finished whale should measure approximately 12 to 14 centimeters (about 5 to 5.5 inches) in length. Keep in mind that gauge varies from crocheter to crocheter, so your whale might be slightly larger or smaller depending on your tension. That’s completely fine — amigurumi are forgiving in that way.

Part One: The Body

The body is the largest piece and the one you’ll work on first. It’s crocheted in one continuous piece, starting from the nose end and working toward the tail.

Round 1: MR, 6 SC into the ring. (6 sts)

Round 2: Inc in each stitch around. (12 sts)

Round 3: SC 1, Inc repeat 6 times. (18 sts)

Round 4: SC 2, Inc repeat 6 times. (24 sts)

Round 5: SC 3, Inc repeat 6 times. (30 sts)

Round 6: SC 4, Inc repeat 6 times. (36 sts)

Round 7: SC 5, Inc repeat 6 times. (42 sts)

Rounds 8 through 14: SC in each stitch around. (42 sts) — These 7 rounds of even crocheting form the body of your whale.

At this point, if you are using safety eyes, insert them between rounds 10 and 11, with approximately 8 to 10 stitches of space between them. Lock the washers on the inside. This is also the moment to embroider the smile if you’d like one — a simple curved line in black or dark brown embroidery thread or yarn looks wonderful.

Round 15: SC 5, Dec repeat 6 times. (36 sts)

Round 16: SC 4, Dec repeat 6 times. (30 sts)

Round 17: SC 3, Dec repeat 6 times. (24 sts)

Begin stuffing your whale at this point. Keep adding stuffing as you close up the body in the next rounds.

Round 18: SC 2, Dec repeat 6 times. (18 sts)

Round 19: SC 1, Dec repeat 6 times. (12 sts)

Round 20: Dec 6 times. (6 sts)

Finish stuffing firmly, then fasten off and use your yarn needle to close the remaining 6 stitches by weaving the tail through each front loop and pulling tight. Weave in the end.

Part Two: The Belly Patch

The belly patch is a simple flat oval that you sew onto the front of the body. It gives your whale that classic two-tone look.

Using your white or cream yarn:

Round 1: MR, 6 SC. (6 sts)

Round 2: Inc in each stitch around. (12 sts)

Round 3: SC 1, Inc repeat 6 times. (18 sts)

Round 4: SC 2, Inc repeat 6 times. (24 sts)

Round 5: SC in each stitch around. (24 sts)

Sl St to close, FO and leave a long tail for sewing.

Flatten the oval and pin it to the belly of your whale, centering it nicely. Using the yarn tail and your needle, sew it down with small, neat stitches all the way around the edge. Weave in the end.

Part Three: The Pectoral Fins

You’ll make two of these. They’re small and quick.

Round 1: MR, 6 SC. (6 sts)

Round 2: Inc in each stitch around. (12 sts)

Round 3: SC 1, Inc repeat 6 times. (18 sts)

Rounds 4 and 5: SC in each stitch around. (18 sts)

Round 6: SC 1, Dec repeat 6 times. (12 sts)

Do not stuff the fins. Flatten them and close the opening by working a row of SC across the top through both layers, connecting the front and back. FO and leave a long tail.

Sew the fins to each side of the body, roughly at rounds 10 through 12, angling them slightly downward and forward so they look natural.

Part Four: The Tail Flukes

The tail is made of two separate pieces sewn together and then attached to the back end of the body. Each fluke is a small rounded flat piece.

Make two flukes in your main color:

Round 1: MR, 6 SC. (6 sts)

Round 2: Inc in each stitch around. (12 sts)

Round 3: SC 1, Inc repeat 6 times. (18 sts)

Rounds 4 and 5: SC in each stitch around. (18 sts)

FO the first fluke. For the second fluke, do not FO. Instead, hold the two flukes together and join them by working 6 SC across the straight edge through both pieces at once. This joins them into one tail piece.

FO and leave a long tail for sewing.

Sew the joined tail piece to the back end of the whale’s body, centering it and stitching all around the base. The two flukes should fan out naturally to the sides, giving that classic whale tail silhouette.

Part Five: The Dorsal Fin

The little fin on the whale’s back is optional but adds a lot of character.

Round 1: MR, 4 SC. (4 sts)

Round 2: Inc in each stitch around. (8 sts)

Round 3: SC 1, Inc repeat 4 times. (12 sts)

Round 4: SC in each stitch around. (12 sts)

Flatten and close the opening with a row of SC through both layers. FO and leave a long tail.

Sew the dorsal fin to the top center of the whale’s back, roughly between rounds 10 and 13.

Part Six: The Spout (Optional)

For an extra playful touch, you can add a little water spout to the top of your whale’s head.

Cut six to eight pieces of blue or white yarn, each about 6 to 8 centimeters long. Gather them together and fold them in half. Using your crochet hook, pull the folded loop through a stitch at the top of the head, then pull all the ends through the loop and tighten. Trim the spout so the ends are even and fan out slightly. It’s the same basic technique used to make fringe or hair on amigurumi figures.

Assembly Tips for a Beautiful Finish

Assembly makes or breaks an amigurumi project. Here are some tips to get the cleanest, most professional-looking result.

Use pins generously before you sew anything permanently. Place each piece where you think it should go, step back, and look at the whale as a whole. Adjust the placement until the symmetry and proportions look right to your eye.

When sewing pieces together, use the same color yarn as the piece you’re attaching. This makes the stitching nearly invisible.

Work through both layers of the piece and into the body stitches for a secure attachment. Amigurumi toys can get handled and squeezed quite a bit, especially by children, so the more securely sewn the better.

Weave your ends in thoroughly — go through several stitches in one direction, turn, and go back through several stitches in another direction before cutting. This prevents the ends from coming loose over time.

Personalizing Your Amigurumi Whale

One of the most delightful things about making amigurumi is how much room there is for personalization. Here are some ideas to make your ballenita truly one of a kind.

You can experiment with color combinations endlessly. A pink and white whale looks like bubblegum candy. A charcoal gray and cream whale looks sophisticated and modern. Variegated or ombre yarns create a beautiful watercolor effect that’s especially lovely for sea creatures.

Adding a bow on top of the whale’s head (between the dorsal fin and the face) or a little flower gives it a feminine, sweet look. A tiny bow tie or sailor collar in a contrasting color gives it a dapper, nautical feel.

You can embroider different expressions to change the whole personality of your whale. Wide round eyes with a big smile feels cheerful and silly. Half-closed eyes with a gentle curved mouth feel calm and dreamy. Embroidered eyelashes add elegance.

If you want to make a matching set, try making a mama whale with a baby whale — just follow the same pattern but use a slightly larger hook or thicker yarn for one and a smaller hook for the other.

Troubleshooting Common Amigurumi Problems

My stitches have gaps and I can see the stuffing. This usually means your tension is too loose, or you’re using a hook that’s too large for your yarn. Try going down a hook size or tightening your tension.

My magic ring keeps coming loose. Make sure you’re pulling the tail end tight before you start crocheting, and lock it in place with your first stitch. Weave the tail in securely at the end.

My whale looks lumpy after stuffing. Try adding stuffing in smaller amounts and distributing it more evenly before closing up. Using good quality polyfill (not clumpy or old stuffing) makes a big difference.

I keep losing my stitch count. Use a stitch marker religiously and count your stitches at the end of every single round. Catching a mistake one round after it happens is much easier than catching it five rounds later.

Caring for Your Amigurumi Whale

If your whale is a gift or a toy that will be played with regularly, knowing how to care for it matters. Most worsted weight acrylic yarns are machine washable on a gentle cycle in a mesh laundry bag. If you used safety eyes, they will hold up fine in the wash. If you used embroidered eyes, the washing machine is also fine.

For whales made from natural fiber yarns like cotton or wool, hand washing in cool water with a gentle soap is safer. Reshape the whale while it’s still damp and let it air dry.

Final Thoughts

Making an amigurumi whale is one of those crochet projects that feels almost meditative once you get into the rhythm of the rounds. The repetitive single crochet stitches give your hands something satisfying to do while your mind wanders, and before you know it you’ve got a little whale body in your lap. The assembly at the end, when all the pieces come together and your whale suddenly has a personality, is a genuinely joyful moment.

Whether you’re making this ballenita for a baby shower gift, a birthday present, a nursery decoration, or simply because you wanted to bring something small and sweet into the world, it’s a project worth taking your time with. Crochet slowly, count carefully, and enjoy the process.

Happy crocheting — and may your little whale bring big smiles.
