In this post, I’m walking you through everything: the materials you need, the abbreviations and stitches used, a full step-by-step pattern, tips for finishing your mouse beautifully, and ideas for personalizing your little critter. Let’s dive in.

What Is Amigurumi and Why Is a Mouse the Perfect Starting Point?

Amigurumi is the Japanese art of crocheting or knitting small stuffed animals and creatures. The word itself comes from “ami,” meaning crocheted or knitted, and “nuigurumi,” meaning stuffed doll. These tiny figures have taken the crafting world by storm, and for good reason: they’re compact, they use small amounts of yarn, and they’re incredibly satisfying to finish.

A mouse is one of the most iconic amigurumi shapes out there. With its round body, big round ears, simple facial features, and little tail, it translates beautifully into the amigurumi format. The shapes are geometric and manageable — mostly circles and ovals — which makes the mouse a fantastic first amigurumi project or a quick, meditative make for experienced crocheters.

As a keychain, the mouse becomes even more practical. Attach it to your bag, your keys, a zipper pull, or a lanyard, and suddenly your handmade work travels with you everywhere. You’ll be surprised how many compliments it earns.

Materials You’ll Need

Before you start, gather your supplies. Because this is a small project, you won’t need much at all, and you may already have everything on hand.

Yarn: You’ll want a lightweight yarn in the weight range of fingering to sport weight (roughly size 1–2) for a truly tiny mouse that works well as a keychain. DK weight yarn (size 3) works beautifully too and gives you a slightly larger finished mouse. Choose a main color for the body (classic gray, soft brown, creamy white, or blush pink are all gorgeous options), a coordinating or contrasting color for the ears (often a pale pink for the inner ear), and a small amount of black or very dark yarn for the eyes if you’re embroidering them.

Crochet Hook: Use a 2.0 mm to 2.5 mm hook for fingering weight yarn, or a 3.0 mm hook for DK weight. Going down a hook size from what the yarn label recommends creates a tighter fabric that holds stuffing neatly without gaps.

Stuffing: Polyester fiberfill is the standard choice. You only need a small pinch for this little mouse. Don’t over-stuff — you want the body to be firm but still slightly squeezable.

Safety Eyes: 4 mm or 5 mm black safety eyes look adorable on a small mouse. If you’re making this for a child under three years old, skip the safety eyes and embroider the eyes with black yarn or thread instead.

Stitch Marker: Just one, to mark the beginning of your rounds, since amigurumi is worked in a continuous spiral.

Tapestry Needle: For weaving in ends and sewing pieces together.

Keychain Ring and Jump Ring: A small keychain ring (the kind you find at any craft or hardware store) and a jump ring to attach your finished mouse. You can also use a lobster claw keychain clip for easy attachment to a bag.

Optional Embellishments: A tiny bow made from ribbon or yarn, a wire whisker set (available at craft stores), or a tiny felt bow for the ears.

Abbreviations and Stitches Used

This pattern uses US crochet terminology. Here’s a quick reference guide:

MR — Magic Ring (also called Magic Loop or Magic Circle)
ch — chain
sl st — slip stitch
sc — single crochet
inc — increase (2 single crochets in the same stitch)
dec — invisible decrease (insert hook in the front loop of the next two stitches and sc them together — this creates an invisible, neat decrease compared to the standard sc2tog)
st(s) — stitch(es)
BLO — back loop only
FLO — front loop only
rnd — round

All rounds are worked in a continuous spiral unless otherwise stated. Do not join rounds with a slip stitch and do not chain at the beginning of rounds. Use a stitch marker to track where each round begins.

Finished Size

Using DK weight yarn and a 3.0 mm hook, the finished mouse measures approximately 6–7 cm (about 2.5 inches) tall from the base to the top of the head, not including the ears or tail. Using fingering weight yarn and a 2.0 mm hook brings the size down to roughly 4–5 cm (under 2 inches), which is truly keychain-scale adorable.

The Pattern

Part One: The Body and Head (Worked in One Piece)

The body and head are worked together in one continuous piece, starting at the base of the body and working upward through the head.

Rnd 1: Start with a MR, work 6 sc into the ring. Pull the ring closed. (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)

Rnds 6–10: sc in each st around. (30 sts) — 5 rounds worked even. This forms the widest part of the body.

Rnd 11: [sc 3, dec] repeat 6 times. (24 sts)

Rnd 12: [sc 2, dec] repeat 6 times. (18 sts)

At this point, insert your safety eyes between rounds 9 and 10, approximately 6–7 stitches apart. If you’re embroidering the eyes, you’ll do that after finishing the entire piece.

Begin stuffing the body firmly with polyester fiberfill before the opening gets too small to reach inside comfortably.

Rnd 13: [sc 1, dec] repeat 6 times. (12 sts)

Rnd 14: sc in each st around. (12 sts)

Rnd 15: Inc in each st around. (24 sts) — This forms the transition into the head, which is slightly wider than the neck.

Rnd 16: [sc 3, inc] repeat 6 times. (30 sts)

Rnds 17–21: sc in each st around. (30 sts) — 5 rounds worked even. This is the main bulk of the head.

Rnd 22: [sc 3, dec] repeat 6 times. (24 sts)

Rnd 23: [sc 2, dec] repeat 6 times. (18 sts)

Add more stuffing to the head now if needed.

Rnd 24: [sc 1, dec] repeat 6 times. (12 sts)

Rnd 25: dec 6 times. (6 sts)

Cut the yarn, leaving a tail. Use your tapestry needle to weave the tail through the front loops of the remaining 6 stitches, pull tight to close, and weave in the end.

Part Two: The Ears (Make Two)

Each ear is made from two circles — an outer ear in your main body color and an inner ear in a contrasting color (traditionally a soft pink). You can make the ears in a single color too if you prefer.

Outer Ear:

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)

Fasten off, leaving a tail for sewing.

Inner Ear:

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

Fasten off, leaving a tail for sewing.

Place the inner ear circle on top of the outer ear circle with wrong sides together and whipstitch around the edge to join them. The seam will be on the back of the ear, hidden when sewn to the head. Leave the bottom of the ear slightly open (about 4 stitches unjoined) so you can fold the ear slightly and give it a cupped shape when attaching it to the head.

Sew the ears to the top of the head, positioned slightly toward the sides. Each ear should sit roughly at the 10 o’clock and 2 o’clock positions when you’re looking at the face. Fold the base of each ear very slightly inward before securing so they have that natural, rounded mouse-ear curve.

Part Three: The Snout (Optional but Adorable)

If you want to add a little pointed snout for extra character, this small piece creates a lovely muzzle.

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 tail. Add a tiny pinch of stuffing before closing. Flatten slightly and sew to the front of the face, centered and positioned in the lower half of the head. With a length of dark yarn threaded through your tapestry needle, embroider a small Y-shaped nose onto the snout — one short vertical stitch from the center top and two diagonal stitches branching down and outward.

Part Four: The Tail

The tail is simply a crocheted chain. With your main color yarn, chain 20 to 30 stitches (adjust for the length you like). Sl st back along the chain for a sturdier tail, or leave it as a plain chain for a more delicate look. Fasten off and attach to the base of the body with a tapestry needle, securing it tightly with several stitches so it doesn’t pull loose.

Part Five: Attaching the Keychain

This is the step that transforms your amigurumi from a little plush into a functioning keychain accessory.

Before closing the head entirely, you have a few options for attaching the keychain hardware. The simplest method is to thread a short loop of strong thread or thin cord through the top of the head using a tapestry needle, then slide the jump ring through the loop and close it. Attach your keychain ring to the jump ring, and you’re done.

A slightly sturdier method is to use a small lobster claw clip with a swivel: use jewelry pliers to open the jump ring slightly, pass it through a couple of stitches at the very top of the head, and close it securely. The swivel means the mouse can spin freely without the yarn at the attachment point getting stressed and worn.

If you want the cleanest, most professional result, you can also sew a small piece of ribbon or sturdy cord into the top seam of the head as you close the final stitches, creating a loop that you can then attach hardware to without any visible stitching on the outside of the finished piece.

Tips for a Beautiful Finished Mouse

Tension is everything. Tight, even tension prevents gaps in your fabric and keeps the stuffing from showing through. If you can see the white stuffing peeking between your stitches, try a smaller hook or hold your yarn with a slightly firmer grip.

The invisible decrease is your best friend. Standard sc2tog creates a small bump on the surface of the fabric. The invisible decrease (working only through front loops of consecutive stitches) gives you a much smoother, rounder finish — especially noticeable on the face and head.

Don’t rush the sewing. The assembly of amigurumi — attaching ears, adding features, sewing the snout — is where a lot of people rush, and it shows. Take your time positioning each piece before you sew it, step back and look at the face from a slight distance, and adjust until it looks exactly right. A few millimeters difference in eye placement or ear angle changes the whole personality of the mouse.

Use a locking stitch marker. Keeping track of your rounds in amigurumi is critical because you’re working in a spiral without joining. A locking stitch marker (the kind that looks like a little safety pin) stays in place even when you’re setting your work down between rounds.

Experiment with color. There’s no rule that says your mouse has to be gray. A soft cream mouse with dusty rose ears and blush accents looks gorgeous. A deep charcoal mouse with sage green accessories has a very different, modern feel. A tiny white mouse with lavender ears would make an amazing Easter or spring gift. Let yourself play.

Customization Ideas

One of the most joyful things about making amigurumi is how endlessly personalizable they are. Here are a few ideas to make your mouse uniquely yours.

You can dress your mouse with a tiny crocheted hat or scarf — both are just small rectangles and simple rounds, and they add enormous charm. A hat made from a contrast color yarn takes maybe fifteen minutes and completely transforms the look.

Adding a small bow between the ears (for a girl mouse vibe) or a tiny crocheted vest (for a dapper mouse vibe) are both simple additions that require only basic crochet shapes.

If you’re making several as gifts, try making a little family: a slightly larger mouse using bulkier yarn paired with two or three tiny ones using finer yarn. They look wonderful displayed together and make an incredibly thoughtful handmade gift set.

For the whiskers, the easiest method is to thread a long piece of thick thread, thin wire, or stiff embroidery floss through the snout with a needle, leaving equal lengths on each side, then trim to your desired whisker length. A tiny drop of fabric glue at the insertion point keeps them from shifting.

Frequently Asked Questions

How long does this mouse take to make? Most crocheters finish the body and head in about 45 minutes to an hour. Add another 20–30 minutes for ears, snout, tail, and assembly. A complete mouse keychain from start to finish typically takes two to three hours for a comfortable pace, and faster once you’ve made a few.

What if I want a bigger mouse? Simply go up a hook size or two and use a heavier yarn. DK weight gives you a mouse about 2.5 inches tall; worsted weight gives you something closer to 3.5–4 inches, which is more of a plush toy than a keychain but still adorable.

Can I sell items made from this pattern? Yes! Items made from this pattern are yours to sell in your own handmade shop, at craft fairs, or as custom commissions. Please don’t sell or distribute the pattern itself.

What’s the best yarn brand for amigurumi? Lion Brand Pound of Love, Paintbox Simply DK, Scheepjes Catona, and Paintbox Cotton DK are all popular choices among amigurumi makers for their consistent tension and wide color range. Scheepjes Catona cotton, in particular, gives a beautifully defined stitch definition that makes tiny pieces look especially crisp.

Do I need to block amigurumi? Generally, no. Amigurumi pieces are three-dimensional and stuffed, so they hold their shape naturally without blocking. If you’re working in cotton and a piece looks a little uneven, a light misting with water and gentle reshaping while damp can help.
