Let’s grab our hooks, put on a cozy playlist, and bring this sweet little sea pup to life!

Why You’ll Love This Amigurumi Seal Project

Crocheting animals (amigurumi) is incredibly rewarding, but there is something uniquely satisfying about a seal. Their naturally round, hydrodynamic shape makes them the ultimate candidate for a squishy, huggable plush toy.

Here is why this specific pattern is going to be your new favorite:

Minimal Sewing: The body and head are worked as one main piece, reducing the tedious assembly lines often found in complex amigurumi.
Perfect for Gifting: From baby showers and nursery decor to cute desk companions for adults, everyone loves a chubby seal.
Great Skill Builder: You will practice basic stitches (single crochet, increases, decreases) while also learning how to shape a muzzle and embroider expressive facial features.
Highly Customizable: You can easily switch up the yarn weight to make a tiny keychain-sized seal or a massive, giant-sized couch pillow!

The Essentials: Tools and Materials

⁠Crochet materials including yarn balls, crochet hooks, vintage scissors, and safety eyes on a wooden craft table.⁠

Before we loop our first slip knot, let’s make sure your crafting desk is stocked with all the essential tools. Using the right materials ensures that your stitches remain tight enough to prevent the stuffing from peeking through, while giving your seal that perfectly smooth, professional look.

1. Yarn Selection

For the classic look pictured above, we recommend a high-quality, sport-weight (4-ply) cotton-acrylic blend or a soft worsted-weight acrylic yarn.

Main Color (MC): Soft Grey or Light Silver (Approx. 60–70 grams).
Muzzle Color (CC1): Cream or Soft Off-White (Small amount, approx. 10 grams).
Detail Colors: A small length of Jet Black embroidery floss or thin yarn for the whiskers, mouth, and nose; plus a touch of Pastel Pink for the embroidered rosy cheeks.

2. Crochet Hook

Size: 2.5 mm or 3.0 mm.
Pro Tip: In amigurumi, you always want to use a hook that is 0.5 mm to 1.0 mm smaller than what the yarn label recommends. This keeps your stitches tight, neat, and structural.

3. Notions & Tools

Safety Eyes: One pair of 10mm or 12mm black gloss safety eyes.
Fiberfill Stuffing: High-quality polyester cloud stuffing to give your seal its signature chubby bounce.
Stitch Markers: Absolutely vital for keeping track of your continuous rounds.
Yarn Needle: A blunt-tipped tapestry needle for sewing the flippers and weaving in loose ends.
Scissors: A sharp pair of embroidery scissors for clean thread cuts.

Understanding the Stitches & Abbreviations

This pattern is written using standard standard US Crochet Terms. Before we start, let’s review the abbreviations used throughout the pattern:

MR: Magic Ring (Magic Circle)
ch: Chain stitch
sc: Single crochet
inc: Single crochet increase (two single crochets worked into the same stitch)
dec: Single crochet decrease (invisible decrease recommended)
st(s): Stitch(es)
sl st: Slip stitch
(abc) x N: Repeat the instructions inside the parentheses N times around.
[N]: The total number of stitches you should have at the end of that specific round.

The Power of the Invisible Decrease (dec)

To ensure your seal looks seamless and professional, always use the invisible decrease rather than a standard single crochet two together (sc2tog). To do this:

Insert your hook into the front loop only of the first stitch.
Immediately insert your hook into the front loop only of the second stitch (you now have three loops on your hook).
Yarn over, and pull through the first two loops.
Yarn over again, and pull through the remaining two loops.
Voila! Your decrease is practically unnoticeable.

The Complete Step-by-Step Amigurumi Seal Pattern

Note: This entire project is worked in continuous spiral rounds. Do not join at the end of each round with a slip stitch or chain 1 unless explicitly directed to do so. Simply move your stitch marker up to the last stitch of each round as you progress.

Part 1: The Main Body & Head

We start from the front of the nose/head and work our way back toward the tail to create a smooth, beautiful teardrop silhouette.

Round 1: Start with Main Color (Grey) yarn. Make a Magic Ring (MR) and work 6 sc into the ring. [6]
Round 2: Work 1 inc into every stitch around. [12]
Round 3: (1 sc, 1 inc) x 6 times. [18]
Round 4: (2 sc, 1 inc) x 6 times. [24]
Round 5: (3 sc, 1 inc) x 6 times. [30]
Round 6: (4 sc, 1 inc) x 6 times. [36]
Round 7: (5 sc, 1 inc) x 6 times. [42]
Round 8: (6 sc, 1 inc) x 6 times. [48]
Round 9: (7 sc, 1 inc) x 6 times. [54]
Round 10: (8 sc, 1 inc) x 6 times. [60]
Rounds 11–22: Work 1 sc in each stitch around (12 structural rounds total for head width). [60]

Placement of Safety Eyes: Stop here for a moment. Insert your safety eyes between Rounds 14 and 15, leaving a gap of roughly 11 to 12 stitches between them. Make sure they line up symmetrically before securing the plastic washers tightly onto the inside back of the eyes.

Round 23: (8 sc, 1 dec) x 6 times. [54]
Round 24: Work 1 sc in each stitch around. [54]
Round 25: (7 sc, 1 dec) x 6 times. [48]
Round 26: Work 1 sc in each stitch around. [48]
Round 27: (6 sc, 1 dec) x 6 times. [42]
Round 28: Work 1 sc in each stitch around. [42]
Round 29: (5 sc, 1 dec) x 6 times. [36]
Round 30: Work 1 sc in each stitch around. [36]

Stuffing Time: Begin firmly stuffing the head area. Shape it with your hands as you push the fiberfill inside, making sure the cheeks look nicely rounded and symmetrical around the eyes.

Round 31: (4 sc, 1 dec) x 6 times. [30]
Rounds 32–36: Work 1 sc in each stitch around (This creates the elongated torso). [30]
Round 37: (3 sc, 1 dec) x 6 times. [24]
Rounds 38–42: Work 1 sc in each stitch around. [24]
Round 43: (2 sc, 1 dec) x 6 times. [18]
Rounds 44–46: Work 1 sc in each stitch around. [18]
Round 47: (1 sc, 1 dec) x 6 times. [12]

Final Stuffing: Fill the rest of the body completely. You want the body to be firm but still retain a slight squish. Do not overstuff the very end of the tail so it can sit flat on a table surface.

Round 48: Work 6 invisible decreases around. [6]
Fasten off your yarn, leaving an 8-inch tail. Thread your tapestry needle through the front loops of the remaining 6 stitches, pull tightly to close up the back loop securely, knot it, and hide the yarn tail deep inside the body.

Part 2: The Soft White Muzzle

The muzzle gives our seal its signature sweet expression. We will crochet this using our Cream or White contrast yarn.

Round 1: Using Cream/White yarn, start with a Magic Ring and work 6 sc into it. [6]
Round 2: Work 1 inc into every stitch around. [12]
Round 3: (1 sc, 1 inc) x 6 times. [18]
Round 4: (2 sc, 1 inc) x 6 times. [24]
Round 5: Work 1 sc in each stitch around. [24]
Fasten off, leaving a generous 12-inch tail for sewing.

Part 3: Front Flippers (Make 2)

These adorable little side flippers help our seal balance nicely on flat wooden surfaces.

Round 1: Using Main Color (Grey), work 6 sc into a Magic Ring. [6]
Round 2: (1 sc, 1 inc) x 3 times. [9]
Round 3: (2 sc, 1 inc) x 3 times. [12]
Round 4: (3 sc, 1 inc) x 3 times. [15]
Rounds 5–8: Work 1 sc in each stitch around. [15]
Round 9: (3 sc, 1 dec) x 3 times. [12]
Round 10: Work 1 sc in each stitch around. [12]

Do not stuff the flippers. Press the opening flat so that the stitches line up horizontally, and work single crochets across both layers together to close the gap. Fasten off, leaving a long tail for attachment.

Part 4: Tail Fins (Make 2)

The back tail fins are shaped similarly to the front flippers but are slightly smaller and sleeker.

Round 1: Using Main Color (Grey), work 5 sc into a Magic Ring. [5]
Round 2: Work 1 inc in each stitch around. [10]
Round 3: (1 sc, 1 inc) x 5 times. [15]
Rounds 4–6: Work 1 sc in each stitch around. [15]
Round 7: (1 sc, 1 dec) x 5 times. [10]
Round 8: Work 5 decreases around. [5]
Fasten off, leaving a sewing tail. You will join the two individual fin tips together at the back base of the main seal body.

Assembly & Bringing the Character to Life

Now that all your components are neatly crocheted, it’s time for the most magical part of the amigurumi process: assembly! This is where your loose parts transform into a creature brimming with personality.

Step 1: Attaching the Muzzle

Place the muzzle right in the center of the face, slightly below the center line of the eyes. Pin it securely into place using sewing pins so it doesn’t shift. Before you sew the final few stitches down, slip a small handful of fiberfill stuffing inside the muzzle to give it a 3D pop. Sew all the way around using a whip stitch, then secure and bury the yarn tail.

Step 2: Custom Embroidering the Face (The Soul of the Design)

Take a long piece of black embroidery thread or thin yarn and your tapestry needle.

The Nose: Embroider an inverted triangle right in the upper center of the white muzzle. Fill it in with horizontal satin stitches until it looks clean and prominent.
The Smile: Bring the needle down from the bottom point of the nose triangle, then branch it out left and right to create a soft, happy “w” shape smile.
Whiskers: Place three thin black lines on each side of the muzzle, radiating outward to mimic natural seal whiskers.
Eyebrows: Add two small slanted lines right above the safety eyes to give your seal an innocent, endearing look.
Rosy Cheeks: Grab your pastel pink thread and stitch a tiny pink block or circle just beneath the outer corners of each eye.

Step 3: Sewing the Flippers & Tail Fins

Pin the front flippers to the sides of the body around Round 20. Angle them slightly downward so they act like kickstands, helping your seal rest beautifully without rolling over. Sew them firmly. Finally, sew the two back tail fins directly onto the closed tip of the rear body, pointing straight back.

Advanced Customization Ideas for Your Craft Brand

If you are running an online shop or preparing for a local craft market, adding unique variations can skyrocket your engagement. Here are a few creative ways to make this pattern uniquely yours:

The Classic Velvet Makeover: Swap out standard cotton yarn for premier velvet or blanket yarn. Use a 5.0mm hook, and your seal will instantly scale up into an incredibly plush, cloud-soft bedtime pillow.
Seasonal Accessories: Crochet a tiny red-and-white Santa hat for the winter holidays, or a small yellow bucket hat and miniature scarf for autumn vibes.
The “Amyliva Flavor”: Add an embroidered wildflower or a tiny sprig of lavender near the flipper to give the plushie that whimsical, handmade studio aesthetic that your followers adore on Pinterest and Instagram.

Ultimate Tips for Selling and Documenting Your Amigurumi

Creating the item is only half the fun—sharing it with the global maker community is where the magic truly blooms. If you want to showcase your work beautifully on your blog or drive high-converting traffic from TikTok and Pinterest, keep these best practices in mind:

Natural Lighting is King: Avoid heavy artificial studio lights if you want a cozy, organic feel. Shoot your photos next to a large window on an overcast day to catch soft, uniform shadows on the wood textures.
Incorporate Props: As seen in our official layout, staging your finished amigurumi next to matching yarn bowls, retro sewing scissors, and delicate dried botanicals tells a compelling story of handmade luxury.
Detailed Descriptions: When listing your items on your shop, always specify safety eye guidelines (note that safety eyes are not recommended for infants under three; use embroidered eyes instead for toddler-safe toys).
