Mouse in Sweater Amigurumi Free Pattern

There is something undeniably charming about a tiny crocheted mouse wearing a little sweater. Whether you are a seasoned amigurumi maker or someone who just discovered the joy of crocheting small stuffed animals, this project has everything you could want — a satisfying challenge, an adorable result, and the pleasure of making something completely from scratch with your own hands. This free pattern will walk you through every step of creating your very own mouse in a sweater amigurumi, from the first magic ring to the final sewn-on ear. Pull out your yarn, grab your hook, and let’s get started.

What Is Amigurumi?

Amigurumi is the Japanese art of crocheting or knitting small stuffed animals and characters. The word itself is a combination of the Japanese words “ami,” meaning crocheted or knitted, and “nuigurumi,” meaning stuffed doll. These little creations have taken the crafting world by storm over the past two decades, and it is easy to see why. They are compact, customizable, and make incredibly thoughtful handmade gifts.

What makes amigurumi so appealing to crocheters of all levels is that the basic construction is always the same — you work in continuous rounds to create a three-dimensional shape, stuff it with polyfill, and then assemble the pieces together. Once you learn the fundamentals, you can make virtually any character you imagine, including this sweet little mouse bundled up in a cozy sweater.

Materials You Will Need

Before diving into the pattern, gather everything on this list so your crafting session goes smoothly. There is nothing more frustrating than discovering you are missing a key supply halfway through a project.

Yarn: You will need a small amount of light gray or medium gray yarn for the mouse’s body, a contrasting color for the sweater (think soft cream, dusty pink, sage green, or classic navy), pink yarn for the inner ears and nose, and a tiny bit of white or cream for the belly patch if you choose to add one. Worsted weight yarn works beautifully for this pattern and gives you a nice, plump mouse with good definition in your stitches.

Crochet Hook: A 3.5mm or 4mm hook pairs well with worsted weight yarn and keeps your stitches tight enough that the stuffing doesn’t show through. If you find your tension is naturally loose, size down by half a millimeter.

Polyfill Stuffing: A standard bag of polyester fiberfill from any craft store will do. You will use a moderate amount for the body and head, and just a tiny pinch for the tail if you stuff it.

Safety Eyes: Two 6mm or 9mm black safety eyes give the mouse its sweet, expressive look. If you are making this for a child under three years old, embroider the eyes with black yarn instead for safety.

Tapestry Needle: You will need this for weaving in ends, assembling pieces, and embroidering details like the nose and mouth.

Stitch Markers: These are optional but incredibly helpful for keeping track of the beginning of your rounds, especially when you are working on the head and body simultaneously.

Scissors

Thin Cardboard or Pipe Cleaner (Optional): If you want to give the tail a bit of shape, wrapping yarn around a thin pipe cleaner is a fun option.

Abbreviations Used in This Pattern

If you are familiar with standard US crochet terminology, you will feel right at home. Here is a quick reference list.

MR — Magic Ring
Ch — Chain
Sl st — Slip Stitch
Sc — Single Crochet
Inc — Increase (2 sc in the same stitch)
Dec — Decrease (invisible decrease: insert hook into front loop of next stitch, then front loop of the following stitch, and complete as one sc)
BLO — Back Loop Only
FLO — Front Loop Only
St(s) — Stitch(es)
Rnd — Round
Rep — Repeat

The pattern is written in continuous rounds unless otherwise noted. Do not join at the end of each round — just keep going and use a stitch marker to track where each round begins.

The Pattern

Head

The head and body are worked separately and then joined. Starting with the head gives you a sense of the character early on, which is always a little motivating.

Using gray yarn, make a magic ring.

Rnd 1: 6 sc into the magic ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: (Sc 1, inc) rep 6 times. (18 sts)
Rnd 4: (Sc 2, inc) rep 6 times. (24 sts)
Rnd 5: (Sc 3, inc) rep 6 times. (30 sts)
Rnd 6: (Sc 4, inc) rep 6 times. (36 sts)
Rnds 7–13: Sc in each st around. (36 sts, 7 rounds)
Rnd 14: (Sc 4, dec) rep 6 times. (30 sts)

At this point, insert your safety eyes between rounds 9 and 10, approximately 8–10 stitches apart. If you prefer, you can wait until after round 15 to position them with more stuffing inside to guide placement.

Rnd 15: (Sc 3, dec) rep 6 times. (24 sts)
Rnd 16: (Sc 2, dec) rep 6 times. (18 sts)

Begin stuffing the head firmly with polyfill. You want it to feel solid and round.

Rnd 17: (Sc 1, dec) rep 6 times. (12 sts)
Rnd 18: Dec 6 times. (6 sts)

Fasten off, leaving a short tail. Use your tapestry needle to close the remaining hole by weaving through the front loops of the 6 stitches and pulling tight. Weave in the end.

Body

The body is slightly larger and has a flat-bottomed shape so the mouse can sit on its own without tipping over.

Using gray yarn, make a magic ring.

Rnd 1: 6 sc into the magic ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: (Sc 1, inc) rep 6 times. (18 sts)
Rnd 4: (Sc 2, inc) rep 6 times. (24 sts)
Rnd 5: (Sc 3, inc) rep 6 times. (30 sts)
Rnd 6: Sc in BLO in each st around. (30 sts) — this creates a nice flat bottom edge
Rnds 7–15: Sc in each st around. (30 sts, 9 rounds)
Rnd 16: (Sc 3, dec) rep 6 times. (24 sts)
Rnd 17: (Sc 2, dec) rep 6 times. (18 sts)

Begin stuffing the body. It should be plump but not so tight that it distorts the shape.

Rnd 18: (Sc 1, dec) rep 6 times. (12 sts)
Rnd 19: Dec 6 times. (6 sts)

Fasten off and close the opening the same way as the head. Set aside.

Sweater

The sweater is crocheted directly onto the body, which gives it a clean, fitted look without any complicated sewing. This is one of the most satisfying parts of the whole project.

With the body completed and stuffed, join your sweater-colored yarn in the back loop from round 6 of the body (the row where you worked BLO). You will be picking up stitches from those unused front loops.

Rnd 1: Working in the front loops of round 6, sc in each st around. (30 sts)
Rnds 2–8: Sc in each st around. (30 sts, 7 rounds)
Rnd 9: (Sc 3, dec) rep 6 times. (24 sts)
Rnd 10: Sc in each st around. (24 sts)

Fasten off and leave a long tail for sewing. You will attach the head after this step, so the neckline of the sweater sits just below where the head meets the body. If you want to add stripes to your sweater, change colors every two rounds — it adds a wonderful preppy charm.

Sweater Sleeves

The sleeves are small and worked in the round. Make two.

Using sweater-colored yarn, make a magic ring.

Rnd 1: 6 sc into the magic ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnds 3–8: Sc in each st around. (12 sts, 6 rounds)

Fasten off, leaving a long tail. Lightly stuff each sleeve. Flatten the opening slightly and sew to the sides of the body at rounds 3–4 of the sweater.

Ears

Make two outer ears using gray yarn and two inner ear pieces using pink yarn.

Outer Ear (make 2 in gray):

Rnd 1: 6 sc into a magic ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: (Sc 1, inc) rep 6 times. (18 sts)
Rnd 4: Sc in each st around. (18 sts)

Fasten off, leaving a tail for sewing. Do not stuff.

Inner Ear (make 2 in pink):

Rnd 1: 6 sc into a magic 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. Place each pink inner ear piece on the corresponding gray outer ear piece and sew them together around the edges with your tapestry needle. Pinch the base of each finished ear slightly before sewing to the head. Position the ears on either side of the top of the head, approximately at rounds 3–5, and sew them securely in place.

Snout

Using gray yarn (or a slightly lighter shade if you have one), make a magic ring.

Rnd 1: 6 sc into the magic 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. Do not stuff the snout. Sew it to the front of the face, centered between the eyes and just below them. Using pink yarn and a tapestry needle, embroider a small V-shaped nose on the snout, and optionally add a tiny curved smile just below it with a few straight stitches.

Tail

The tail is a simple crocheted chain with a slip-stitch return, giving it a rounded, cord-like appearance.

Using gray yarn, chain 25. Starting from the second chain from the hook, sl st back down the entire chain to create a rounded tail. Fasten off, leaving a tail end to sew onto the body. Attach the tail to the lower back of the body, pulling it through from the inside for a clean finish. If you want the tail to curve naturally, gently shape it while the yarn is still a little loose or run a thin pipe cleaner through the center before attaching.

Assembly

Now comes the most rewarding part — putting your mouse together.

Sew the head to the body using your tapestry needle and a length of gray yarn, making sure it is centered and the face is pointing forward. Pull the yarn tightly as you work your way around the join so there are no gaps. Add a touch more stuffing through the neck opening before you close it up completely if the body or head feels a little soft.

Check your mouse from all angles. Adjust the ear placement if needed, and make sure the snout is centered. The sweater sleeves should hang naturally at the sides.

If you have any long tails left, weave them in securely using your tapestry needle. Give the mouse a gentle squeeze to redistribute the stuffing, and your little friend is complete.

Customization Ideas

One of the greatest joys of amigurumi is how easy it is to put your own stamp on a pattern. Here are some ideas to make your mouse uniquely yours.

Sweater color and texture: Try using a semi-variegated yarn for an instantly interesting sweater without having to switch colors. Or work the sweater rows in a textured stitch like the moss stitch or seed stitch for a more knitted look.

Add a scarf: Chain about 60 stitches and work two rows of single crochet for a simple scarf. Wrap it around the mouse’s neck and tack it in place with a couple of stitches.

Add tiny buttons: Sew two or three miniature buttons down the front of the sweater for a sweet, tailored look.

Make a family: Use the same base pattern but vary the size. Work with fingering weight yarn and a 2mm hook for a tiny baby mouse, or use bulky yarn and a 5mm hook for a larger parent mouse.

Glasses: Bend a small length of thin wire or use a pre-made mini accessory frame to give your mouse a scholarly look.

Give them a prop: A tiny crocheted book, a miniature ball of yarn, or a little crocheted acorn makes for an adorable finished photo.

Tips for Amigurumi Beginners

If this is one of your first amigurumi projects, welcome — you are going to love it. A few practical tips will make the process much smoother.

Work tightly. Amigurumi looks best when the stitches are snug enough that the stuffing doesn’t peek through. If you find your stitches gaping, try going down a hook size.

Use a stitch marker religiously. Losing track of your round starts is one of the most common frustrations in amigurumi. Move your marker every single round without fail.

Don’t rush the stuffing. Stuff as you go toward the end of each piece, rather than trying to cram everything in through a tiny opening at the last second. Firm, even stuffing makes all the difference in the final shape.

Be patient with assembly. The sewing stage takes longer than most people expect, and it is also what elevates the finished piece from “pretty good” to “absolutely adorable.” Take your time positioning each piece, pin them with stitch markers before committing, and sew slowly.

Practice your invisible decrease. The invisible decrease (working through the front loops only) leaves a much cleaner look than the standard decrease, and it is worth getting comfortable with early on since amigurumi uses it constantly.

Sharing Your Make

Once your mouse in a sweater is complete, share it with the world. Post a photo to Instagram with the hashtag #amigurumi or #mouseinamigurumi, or join one of the many wonderful crochet communities on Ravelry, Reddit, or Facebook groups dedicated to amigurumi makers. The handmade community is one of the warmest and most encouraging corners of the internet, and seeing other makers’ takes on the same pattern is endlessly inspiring.

If you gifted your mouse to someone, ask them to send you a photo of it in its new home. There is nothing quite like seeing a little crocheted creature you made with your own hands sitting on someone’s bookshelf or desk, making someone smile every time they look at it.

Final Thoughts

This mouse in sweater amigurumi free pattern is designed to be approachable for crafters at a range of skill levels while still offering enough detail and personality to make the finished piece feel special. The combination of the classic amigurumi mouse form with the cozy, dressed-up sweater element makes it a project people genuinely love to make and to receive. Whether you whip one up as a gift, a decoration, or simply for the pleasure of the craft itself, there is a particular magic in transforming a ball of yarn into a tiny, squishy, fully dressed mouse.

Happy crocheting, and enjoy every single stitch.
