This guide is written for crocheters who are comfortable with the basics — magic rings, single crochet, increases, and decreases — but even if you’re fairly new to amigurumi, you’ll find the instructions clear and easy to follow. Let’s dive in.

What Is Amigurumi?

Amigurumi is the Japanese art of crocheting or knitting small stuffed animals and characters. The word itself combines the Japanese words for “knitted” and “stuffed doll.” These little figures became wildly popular in Japan in the 1980s and have since swept the global crafting community, showing up at craft fairs, on Etsy shops, and in the hands of crocheters everywhere from beginners to seasoned pros.

What makes amigurumi so appealing is the combination of simplicity and results. Most amigurumi are worked in continuous rounds (called spirals) using single crochet stitches, which means once you understand the basic structure, you can make virtually any animal or character you can imagine. The baby seal in this pattern is a wonderful example of how a handful of simple techniques come together into something truly charming.

Materials You’ll Need

Before you start crocheting, gather everything listed below. Having your supplies ready before you begin makes the process much smoother.

Yarn: Worsted weight yarn (size 4) in the following colors:

• White or cream for the body (approximately 80–100 yards)
• Light gray or silver for optional shading on the back (approximately 20 yards)
• Black for the nose and any details (a small amount)

Hook: 3.5mm or 4.0mm crochet hook (use the smaller hook for a tighter fabric that won’t let stuffing show through)

Other supplies:

• Polyester fiberfill stuffing
• Two 9mm or 12mm black safety eyes
• Yarn needle (tapestry needle) for sewing pieces together
• Stitch marker to track your rounds
• Scissors

Optional: A small amount of pink yarn or embroidery floss for cheeks or inner ear detail.

Abbreviations Used in This Pattern

• MR — Magic ring
• SC — Single crochet
• INC — Increase (2 SC in the same stitch)
• DEC — Invisible decrease (insert hook through front loops of next 2 stitches, yarn over, pull through, yarn over, pull through 2 loops)
• SL ST — Slip stitch
• CH — Chain
• BLO — Back loop only
• St(s) — Stitch(es)
• Rnd — Round

All rounds are worked in a continuous spiral unless otherwise noted. Use a stitch marker to mark the first stitch of each round.

Pattern Notes

The finished baby seal measures approximately 5 to 6 inches long and 3 to 4 inches tall when made with worsted weight yarn and a 3.5mm hook. You can make it larger by using bulky yarn and a bigger hook, or smaller by using fingering weight yarn and a 2.5mm hook.

The seal’s body is worked from the nose backward toward the tail. The flippers are made separately and sewn on after the body is assembled. The entire project takes most crafters between three and five hours, making it ideal for a cozy afternoon or a relaxed weekend sit-down.

Part One: The Body

The body is the largest piece and the one you’ll start with. Working from the nose toward the tail gives the seal its naturally tapered shape.

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

Rnd 2: INC in each st around. (12 sts)

Rnd 3: [SC 1, INC] repeat 6 times. (18 sts)

Rnd 4: [SC 2, INC] repeat 6 times. (24 sts)

Rnd 5: [SC 3, INC] repeat 6 times. (30 sts)

Rnd 6: [SC 4, INC] repeat 6 times. (36 sts)

Rnds 7–10: SC in each st around. (36 sts) — 4 rounds even

At the end of Round 10, this is the widest part of the seal’s body — its round, pudgy belly area. Before continuing, go ahead and attach your safety eyes between Rounds 7 and 8, approximately 8 to 10 stitches apart. This placement gives the seal that wide, endearing look that makes baby seals so irresistible.

Rnd 11: [SC 4, DEC] repeat 6 times. (30 sts)

Rnd 12: SC in each st around. (30 sts)

Rnd 13: [SC 3, DEC] repeat 6 times. (24 sts)

Rnd 14: SC in each st around. (24 sts)

Rnd 15: [SC 2, DEC] repeat 6 times. (18 sts)

Now is a good time to begin stuffing the body. Fill it firmly but not so tightly that the fabric stretches and shows the stuffing through the stitches. Continue adding small amounts of stuffing as you close the body.

Rnd 16: [SC 1, DEC] repeat 6 times. (12 sts)

Rnd 17: DEC 6 times. (6 sts)

Fasten off, leaving a short tail. Use your yarn needle to weave through the remaining 6 stitches and pull tight to close. Weave in the end securely.

Part Two: The Nose

The nose is a small, simple piece that gives the seal its most expressive feature.

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

Rnd 2: INC in each st around. (12 sts)

Rnd 3: SC in each st around. (12 sts)

Fasten off, leaving a long tail for sewing. Leave the nose unstuffed — it should sit flat against the face when sewn on. Position it at the very tip of the body (the nose-end where you started your magic ring) and sew it in place with your yarn needle, tucking in any loose fibers as you go. Once the nose piece is attached, use a small length of black yarn or black embroidery floss to stitch a simple Y-shape or two small dots on the front of the nose piece to suggest nostrils. This tiny detail makes a surprisingly big difference in the finished look.

Part Three: The Front Flippers

Make two. The front flippers are oval-shaped paddles that give the seal its characteristic pose — that adorable baby-seal look of lying flat with its flippers pressed to its sides.

Rnd 1: CH 7. Starting in the second chain from the hook: SC 5, then work 3 SC into the last chain (the chain at the far end). Rotate and work back along the other side of the foundation chain: SC 4, INC into the first chain. (14 sts)

Rnd 2: INC, SC 4, INC 3 times, SC 4, INC. (20 sts)

Rnd 3: SC in each st around. (20 sts)

Rnd 4: [SC 3, DEC] repeat 4 times. (16 sts)

Rnd 5: [SC 2, DEC] repeat 4 times. (12 sts)

Flatten the flipper so the two sides are even. Do not stuff. Slip stitch across the open end to close, or simply sew the opening closed with your yarn needle. Fasten off, leaving a long tail for attaching to the body.

Sew the front flippers to either side of the body, positioning them roughly at the widest part of the belly. Angle them slightly downward and forward so they look natural, as if the seal is resting on them. Take your time with the placement — holding the flippers against the body before sewing gives you a good sense of whether the positioning feels right.

Part Four: The Hind Flippers (Tail Fins)

The hind flippers are worked as a single piece that forms the tail. This is what gives the amigurumi seal its instantly recognizable silhouette.

Make two flipper lobes, then join them:

Lobe (make 2):

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

Rnd 2: INC in each st around. (12 sts)

Rnd 3: [SC 1, INC] repeat 6 times. (18 sts)

Rnds 4–5: SC in each st around. (18 sts)

Fasten off the first lobe. For the second lobe, do not fasten off — you will use this working yarn to join the two lobes together.

Joining round: SC across 9 sts of the second lobe, then SC across 9 sts of the first lobe. (18 sts total)

Rnd 1 (after joining): SC in each st around. (18 sts)

Rnd 2: [SC 1, DEC] repeat 6 times. (12 sts)

Rnd 3: DEC 6 times. (6 sts)

Fasten off, leaving a long tail. Do not stuff the tail piece — it should be flat. Sew it to the back end of the body (the closing point of your body piece). Arrange it so the two lobes flare out to the sides, like a real seal’s hind flippers, and stitch it firmly in place.

Part Five: Assembly and Finishing

Once all your pieces are made, the fun part begins — putting your seal together and watching it come to life.

Start by laying out all the pieces: the body (with safety eyes already attached), the nose, the two front flippers, and the tail. Take a moment to arrange them the way you’d like them to look before you start sewing. Amigurumi assembly is one of those steps where a little planning goes a long way.

Attach the nose first, since it’s the focal point of the face. Then sew on the front flippers, followed by the tail. As you sew each piece, try to hide your knots and yarn tails inside the body of the seal, pulling them through with your yarn needle and trimming them close so they disappear into the stuffing.

If you’d like to add rosy cheeks, cut a small circle from pink felt and glue it onto the face with fabric glue, or use a few stitches of pink embroidery floss in a satin stitch to create a blushing effect. This detail is entirely optional but adds so much sweetness to the finished seal.

Tips for the Best Results

Taking good care of a few key details will make a noticeable difference in how polished your finished seal looks.

Use the invisible decrease throughout this pattern instead of a standard decrease. The invisible decrease (worked through the front loops only of two consecutive stitches) creates a much smoother surface with no visible gaps or holes, which is especially important for a pale-colored yarn where imperfections show up easily.

Stuff firmly, but check as you go. Understuffed amigurumi tend to look lumpy and saggy over time. Overstuffed ones look strained at the seams. Aim for a plush firmness — squeezable but with a shape that holds itself.

When sewing pieces together, use the same yarn you crocheted with whenever possible. Matching thread or a contrasting color can show through even with careful sewing, while matching yarn blends in beautifully.

If you plan to give this seal to a child under three, skip the safety eyes and embroider the eyes instead using black yarn in a satin stitch. Safety eyes are secure but not intended for very young children who might pull or mouth them.

Customizing Your Baby Seal

One of the most joyful parts of making amigurumi is how easy they are to personalize. Here are a few ideas to make your seal your own:

You could make a spotted seal by using a variegated gray-and-white yarn or by adding small French knots in a contrasting color after finishing. Gray spots scattered across the back give a realistic harp seal effect that looks gorgeous.

A tiny crocheted bow or a miniature scarf worked in a contrasting color and tied around the seal’s neck transforms it from a simple plush toy into a gift-ready keepsake. Small bows work especially well in pastel colors for baby shower gifts.

For a bigger seal, simply size up. Use super bulky yarn (size 6) with a 6mm hook and you’ll end up with a seal nearly twice the size, perfect as a pillow or a stuffed animal for a toddler.

You can also experiment with color to make arctic seals (bright white), harbor seals (mottled gray), or even a fantasy seal in lavender or mint green if you’re making this purely for charm rather than realism.

Caring for Your Finished Amigurumi

Handmade crochet items made with acrylic yarn are generally machine washable on a gentle cycle inside a mesh laundry bag, then air-dried flat. If you use wool or a wool blend, hand washing in cool water is the safer choice to prevent felting.

If the seal is meant as a decorative item rather than a toy, you can also lightly stuff it with lavender buds mixed into the fiberfill for a subtle, calming scent that makes it even more appealing as a shelf or nursery decoration.

A Few Final Thoughts

There’s something genuinely satisfying about turning a few skeins of yarn into a creature with so much personality. The baby seal in this pattern has a simplicity to it that makes it approachable even if you’re still building your amigurumi confidence, and the end result is so undeniably cute that it’s hard to stop at just one. Many crafters who make this pattern end up making a whole colony of seals in different colors for gifts, markets, or just the sheer pleasure of it.

If you make this pattern, consider sharing your finished seal on social media and tagging it with amigurumi-related hashtags — the crochet community is one of the warmest and most encouraging corners of the internet, and seeing other crafters’ interpretations of the same pattern is always a delight.

Happy crocheting, and enjoy every stitch of your adorable little seal pup.
