Let’s dive into everything you need to know before you pick up your hook.

Why Make an Amigurumi Guinea Pig?

Guinea pigs hold a very special place in the hearts of small pet lovers everywhere. They’re gentle, expressive, and have that unmistakable chubby round shape that translates perfectly into amigurumi. Unlike cats or dogs, which have been done countless times in crochet, a guinea pig brings something a little more unique to your project lineup.

Amigurumi as a craft style originated in Japan and has since become one of the most popular niches in the crochet world. The technique uses tight single crochet stitches worked in continuous rounds to create a firm, stuffed fabric that holds the shape of whatever creature or character you’re making. Guinea pigs are an ideal subject because their bodies are essentially a large rounded oval, their faces are simple and expressive, and their tiny ears and feet add just the right amount of detail without becoming complicated.

This pattern is especially well-suited for crocheters who want to practice working in the round, increasing and decreasing evenly, and achieving a consistent tension. Once you’ve made one guinea pig, you’ll find the techniques carry over to hundreds of other amigurumi patterns.

Materials You’ll Need

Before you begin, gather the following supplies. The beauty of amigurumi is that it uses very small amounts of yarn, so this is a great stash-busting project.

Yarn: Worsted weight (category 4) yarn works best for this pattern. You’ll need a main color for the body, which could be anything from a warm caramel brown to a soft white, a deep black, or a classic tortoiseshell blend. You’ll also want a small amount of a contrasting color if your guinea pig has markings, and a tiny bit of pink or blush-toned yarn for the inner ears and nose area.

Hook: A 3.5mm crochet hook is recommended for worsted weight yarn when working amigurumi, as you want a tight gauge that prevents stuffing from showing through. If your tension tends to run loose, go down to a 3.25mm.

Stuffing: Polyester fiberfill, also called polyfill, is the standard choice. It’s lightweight, washable, and gives a satisfying firmness. Make sure to stuff as you go rather than waiting until the end, especially for the body and head.

Safety eyes: 12mm black safety eyes work perfectly for an adult-looking guinea pig. If you’re making this toy for a child under three, you can embroider the eyes with black yarn instead for safety.

Yarn needle: Even though this is a no sew pattern, you’ll still use a yarn needle to weave in your ends and to embroider any facial details.

Stitch markers: These are essential for amigurumi. Use them to mark the first stitch of each round so you don’t lose your place.

Scissors

Gauge and Finished Size

With worsted weight yarn and a 3.5mm hook, your finished guinea pig should measure approximately 5 inches long and 3.5 inches tall. Amigurumi is not especially gauge-sensitive in the way that wearables are, but if your tension is very different from average, your finished size will vary. The proportions are what matter most, so as long as your increases and decreases are placed correctly, your guinea pig will look right regardless of slight size differences.

Abbreviations (US Terms)

This pattern is written in US crochet terminology. Here’s a quick reference for the abbreviations used throughout:

MR — magic ring
ch — chain
sc — single crochet
inc — increase (2 single crochets in the same stitch)
dec — invisible decrease (insert hook through the front loops of the next two stitches and complete as one single crochet)
sl st — slip stitch
BLO — back loop only
FLO — front loop only
st(s) — stitch(es)
rnd — round

The Pattern

Head

The head and body of this guinea pig are worked as separate pieces and then joined using the no sew method, meaning the last round of each piece is crocheted together rather than sewn.

Rnd 1: Start with a magic ring, 6 sc into the ring. (6)
Rnd 2: Inc in each st around. (12)
Rnd 3: *sc 1, inc* repeat 6 times. (18)
Rnd 4: *sc 2, inc* repeat 6 times. (24)
Rnd 5: *sc 3, inc* repeat 6 times. (30)
Rnd 6: *sc 4, inc* repeat 6 times. (36)
Rnd 7: *sc 5, inc* repeat 6 times. (42)
Rnds 8–13: sc around. (42)
Rnd 14: *sc 5, dec* repeat 6 times. (36)
Rnd 15: *sc 4, dec* repeat 6 times. (30)

Before continuing, attach your safety eyes between rounds 11 and 12, spaced about 8 stitches apart. Stuff the head firmly and continue decreasing.

Rnd 16: *sc 3, dec* repeat 6 times. (24)
Rnd 17: *sc 2, dec* repeat 6 times. (18)
Rnd 18: *sc 1, dec* repeat 6 times. (12)

Stuff fully. Fasten off, leaving a long tail to join to the body.

Body

Rnd 1: MR, 6 sc. (6)
Rnd 2: Inc in each st. (12)
Rnd 3: *sc 1, inc* repeat 6 times. (18)
Rnd 4: *sc 2, inc* repeat 6 times. (24)
Rnd 5: *sc 3, inc* repeat 6 times. (30)
Rnd 6: *sc 4, inc* repeat 6 times. (36)
Rnd 7: *sc 5, inc* repeat 6 times. (42)
Rnd 8: *sc 6, inc* repeat 6 times. (48)
Rnds 9–20: sc around. (48)
Rnd 21: *sc 6, dec* repeat 6 times. (42)
Rnd 22: *sc 5, dec* repeat 6 times. (36)

Stuff the body well at this point. Guinea pigs have a very round, full shape, so don’t be shy with the fiberfill.

Rnd 23: *sc 4, dec* repeat 6 times. (30)
Rnd 24: *sc 3, dec* repeat 6 times. (24)

Leave the last 24 stitches open. Place the head against the open end of the body and use the tail from the head to single crochet through both layers, joining the two pieces together. This is the no sew technique — you’re essentially crocheting the head onto the body in a clean seam. Fasten off and weave in the end.

Ears (make 2)

Rnd 1: MR, 6 sc. (6)
Rnd 2: Inc in each st. (12)
Rnd 3: sc around. (12)

Fasten off, leaving a long tail. Flatten the ear slightly so it forms an oval shape. Position each ear on the top of the head between rounds 5 and 7, spaced evenly. To attach without sewing, use your hook to pull the tail through the stitches on the head and lock it in place by weaving it through several nearby stitches in different directions. This creates a secure join without any visible seam.

Front Legs (make 2)

Rnd 1: MR, 6 sc. (6)
Rnd 2: Inc in each st. (12)
Rnds 3–4: sc around. (12)
Rnd 5: *sc 1, dec* repeat 4 times. (8)
Rnds 6–10: sc around. (8)

Stuff lightly. Flatten the top of the leg and use the no sew join method to attach to the sides of the body near the front, crocheting through both the leg opening and the body stitches. Fasten off and weave in ends.

Back Legs (make 2)

Rnd 1: MR, 6 sc. (6)
Rnd 2: Inc in each st. (12)
Rnd 3: *sc 1, inc* repeat 6 times. (18)
Rnds 4–5: sc around. (18)
Rnd 6: *sc 1, dec* repeat 6 times. (12)
Rnds 7–9: sc around. (12)

Stuff lightly and attach to the lower back sides of the body using the same no sew method as the front legs.

No Sew Joining Explained

If you’re new to no sew amigurumi, the concept might feel a little unfamiliar at first, but it quickly becomes one of the most satisfying techniques in crochet. The idea is simple: rather than closing off a piece completely and then trying to stitch it onto another piece with a yarn needle, you leave the final round open and use your hook to single crochet through both pieces simultaneously.

To do this, hold the piece you’re attaching against the place on the body where you want it to sit. Insert your hook through one stitch of the open piece and then through the corresponding stitch on the body. Draw up a loop and complete a single crochet. Continue around until all stitches are joined. The result is a neat, even seam that looks intentional and professional.

For pieces like the ears and legs where you’re attaching to the surface of the body rather than joining open rounds, you can thread the tail onto a yarn needle and weave it through the stitches of the body in a figure-eight pattern, creating an invisible and very secure join without any surface stitching showing.

Adding Facial Details

The face is where your guinea pig really comes to life. Once your safety eyes are in place, use a small amount of pink or blush yarn to embroider a simple nose just below center between the eyes. A small Y-shape or a rounded triangle both work well.

You can also use a single strand of black embroidery floss to add a faint line beneath the nose suggesting the mouth, though many people find the eyes and nose alone are expressive enough.

If you want your guinea pig to have that classic rosette or fluffy forelock that long-haired breeds like Peruvian guinea pigs are known for, you can use the loop stitch (also called the fur stitch) on rounds 5 and 6 of the head to create a tuft of hair right between the ears. Simply insert your hook, wrap the yarn around your finger to form a loop, then draw through both strands and complete as a single crochet. This creates a standing loop that gives a very realistic fluffy texture.

Customization Ideas

One of the most enjoyable parts of making amigurumi is making each one unique. Here are some ways to personalize your guinea pig:

Color combinations: Guinea pigs come in an enormous range of patterns in real life, including solid, roan, tortoiseshell, Dutch (white with colored patches), and Himalayan (white with darker points). Use multiple colors in your yarn to replicate these patterns by changing colors at the beginning of a round or by working surface crochet patches onto a finished piece.

Long-haired varieties: For a Peruvian or Silkie guinea pig, work the body in the loop stitch throughout to create that flowing, fluffy texture. The result is incredibly realistic and very eye-catching.

Accessories: Tiny crocheted scarves, hats, or even miniature vegetables are easy add-ons that make for irresistible photos and gift presentations. A little orange carrot held in the front paws is particularly charming.

Sizing up or down: Use bulky yarn and a larger hook for an oversized guinea pig plush, or use fingering weight yarn and a 1.5mm hook for a tiny miniature version.

Tips for Success

Working in a continuous spiral rather than joining at the end of each round gives amigurumi its smooth, seamless look. Always use a stitch marker to track your first stitch of each round, because once you remove it, it can be very difficult to figure out where one round ends and the next begins.

The invisible decrease (inserting through the front loops of two stitches before completing) creates a much flatter, neater decrease than the standard single crochet two together. It takes a moment to get used to but makes a significant difference in the finished appearance, especially around the face.

Stuffing is an art in itself. Too little stuffing results in a floppy, sad-looking amigurumi. Too much can distort the stitches and cause white fiberfill to show through gaps. The sweet spot is firm but not stretched. Add a little at a time and check the shape frequently.

Frequently Asked Questions

Can a beginner make this pattern? Yes. If you can make a magic ring, single crochet, increase, and decrease, you have everything you need. The no sew joining technique is explained in detail within the pattern itself.

Is this pattern suitable for children? With safety eyes swapped for embroidered ones, absolutely. Always use embroidered eyes for toys intended for children under three years old.

Can I sell items made from this pattern? Yes, items made from this pattern may be sold. Please credit the pattern designer when selling or sharing online.

What if I run out of yarn partway through? Join new yarn at the beginning of a round whenever possible and weave the ends in securely on the inside. With amigurumi, your ends are always hidden inside the stuffed piece, which makes this much easier than in flat crochet.

Can I use a different yarn weight? You can, keeping in mind that your finished size will change. If you use bulky yarn, you may want to add an extra increase round or two to the body to keep the proportions looking right.

There’s something deeply satisfying about crocheting a small animal from a ball of yarn and watching it take shape stitch by stitch. Guinea pigs have such a distinct, loveable silhouette that they’re a joy to work up, and the no sew technique means you’ll finish with a polished project rather than a frustrating assembly puzzle. Whether this is your very first amigurumi or your fiftieth, this little guinea pig is ready to be made, gifted, and adored.
