Free Mouse Knitting Pattern: My Tiny Mouse Keychain

If you’ve ever wanted a knitting project that fits in the palm of your hand, takes less than an evening to finish, and ends up being absolutely irresistible to everyone who sees it, this tiny mouse keychain is exactly what you’ve been looking for. I’ve been knitting these little critters for years — slipping them onto my bag, gifting them to friends, and stuffing them into birthday cards as a sweet extra surprise. Today I’m sharing my full free mouse knitting pattern so you can make one (or ten) for yourself.

This pattern is beginner-friendly with just a touch of shaping, so it’s perfect if you’re newer to knitting in the round or working with double-pointed needles. If you’ve already got a few small projects under your belt and want something fast and satisfying, this one will absolutely deliver.

Why I Love This Little Mouse

There’s something undeniably charming about miniature knitted animals. The mouse in particular has this wonderful combination of simplicity and personality — the rounded body, the tiny ears, the long looping tail. Mine hangs from my keychain alongside my house keys, and I genuinely cannot count how many times a stranger has leaned in to say “wait, is that a knitted mouse?”

Beyond the cuteness factor, this project is incredibly practical from a knitter’s perspective. It uses a small amount of yarn — we’re talking scraps, really — so it’s a brilliant stash buster. You can use leftovers from almost any project, which means you can make a whole family of mice in different colors without spending a single extra dollar on yarn. I’ve made them in classic grey, soft brown, white, and even a rather festive red for Christmas ornaments.

It also knits up quickly. Once you’re familiar with the pattern, you can finish the body in an hour or two. Add ears, the tail, a little face, and you’re done. It’s the kind of project you can bring along to a waiting room or a long car ride and actually finish before you get home.

Materials You’ll Need

Before we dive into the pattern itself, let’s talk supplies. Part of what makes this mouse keychain so accessible is that you probably already have everything you need.

Yarn: A small amount of worsted weight yarn in your chosen mouse color. Think grey, brown, cream, tan, or whatever strikes your fancy. Roughly 10–15 yards is all you need for the body, with a few extra yards for the ears. You’ll also want a tiny bit of black or dark brown yarn or embroidery thread for the nose and eyes.

Needles: US size 2 or 3 (2.75–3.25mm) double-pointed needles, or a short circular needle if you prefer magic loop. The slightly smaller needle size than you’d normally use for worsted yarn gives the fabric a nice tight tension that keeps the stuffing from peeking through.

Other supplies:
A small amount of polyfill stuffing or yarn scraps for stuffing the body. A yarn needle for seaming and weaving in ends. A keychain ring (the split ring style works great). A small length of wire-core ribbon or a piece of thin cord for the tail, or you can use a braided yarn tail. Scissors. Stitch markers.

Optional: tiny wiggle eyes or safety eyes in 4mm or 6mm size, depending on how small you want the face to be. I personally love the look of simple embroidered eyes — it gives the mouse a softer, more handmade feel — but safety eyes are quicker and totally adorable too.

Pattern Notes

This mouse is knitted in the round from the nose down to the base. The body is shaped with simple increases and decreases, worked in stockinette stitch. The ears are worked flat as small circles and then sewn on. The tail is attached last.

Gauge: Gauge is not critical for this project since we’re going for a small, firm fabric. That said, aim for roughly 6–7 stitches per inch in stockinette so the body holds its shape nicely.

Free Mouse Knitting Pattern: The Body

Cast on:
Using the long-tail cast on method, CO 6 sts onto your DPNs, distributing 2 sts per needle (if using 3 needles) or however works best for you. Join to work in the round, being careful not to twist. PM to mark the beginning of the round.

Rnd 1: Kfb in each stitch around. (12 sts)

Rnd 2: Knit all sts.

Rnd 3: K1, Kfb repeat to end of round. (18 sts)

Rnd 4: Knit all sts.

Rnd 5: K2, Kfb repeat to end of round. (24 sts)

Rnds 6–16: Knit all sts. (Work even for 11 rounds. This forms the main body of the mouse.)

Rnd 17: K2, K2tog repeat to end of round. (18 sts)

Rnd 18: Knit all sts.

At this point, begin stuffing the body lightly with polyfill. You don’t want it too tight or too loose — just enough to give the mouse a firm, rounded shape without distorting the stitches.

Rnd 19: K1, K2tog repeat to end of round. (12 sts)

Rnd 20: Knit all sts.

Continue stuffing if needed.

Rnd 21: K2tog repeat to end of round. (6 sts)

Cut your yarn, leaving a 6-inch tail. Thread the tail through your yarn needle and draw it through the remaining 6 stitches. Pull tight to close the hole, then pass the needle through to the inside of the mouse and secure. Weave in this end inside the body so it stays hidden.

The Ears (Make 2)

The ears are worked flat as tiny circles.

CO 3 sts.

Row 1: Kfb, K1, Kfb. (5 sts)

Row 2: Purl all sts.

Row 3: Kfb, K3, Kfb. (7 sts)

Row 4: Purl all sts.

BO all stitches.

Leave a long tail for sewing. Position each ear on the upper front portion of the mouse’s body, about one-third of the way down from the nose end. The ears should sit on opposite sides of the head, angled slightly outward and forward. Use the long tail to sew each ear in place with a few secure stitches, then weave the end into the body and trim.

If you want slightly rounder, more three-dimensional ears, you can work the ear as a small circle using a provisional cast on and then fold it slightly before sewing it on. But the flat version gives a lovely classic mouse silhouette and is much simpler, especially for beginners.

The Face

This is where your mouse really comes to life, and I encourage you to have fun with it.

Eyes: Using black embroidery thread or a short length of dark yarn, make two small satin stitches or French knots on either side of the face, roughly in the middle of the head. Space them about 4–5 stitches apart. If you’re using safety eyes, push them through before you fully close the bottom of the body in the final decreasing rounds.

Nose: Work a small cluster of 2–3 satin stitches at the very tip of the nose (the cast-on end of your work) using a tiny bit of pink or dark brown embroidery thread. This tiny detail makes such a big difference in the overall look. Some knitters also add a single stitch of thread to suggest a mouth — a tiny downward curve below the nose — and it’s endlessly charming.

Whiskers (optional): Thread a thin piece of nylon thread, fishing line, or light-colored embroidery thread through the nose area and trim to equal lengths on both sides. Whiskers are completely optional but they do take the mouse to a whole new level of adorableness. If you’re making these for small children, skip the whiskers since the loose ends could be a hazard.

The Tail

For the tail, you have a few options depending on the look you want.

Braided yarn tail: Cut three strands of yarn about 6 inches each. Fold them together, knot one end, braid tightly, and knot the other end. Thread the knotted end through to the inside of the mouse at the base (the bound-off end), secure it, and let the braided tail hang free. Trim to your desired length. This gives a sturdy, textured tail.

I-cord tail: If you want a longer, smoother tail, work a short I-cord. Cast on 3 stitches and work an I-cord for about 2–3 inches, then bind off. Attach to the base of the mouse in the same way as the braided tail.

Embroidery thread tail: For the thinnest, most delicate tail, use several strands of embroidery thread braided or twisted together. This works especially well if you’re making a very small mouse and want the tail to stay proportional.

Attaching the Keychain Ring

Once your mouse is fully assembled, take your split keychain ring and loop it around the braided or I-cord tail at the base, just above where the tail meets the body. The ring will sit right where the tail emerges, giving the mouse a little anchor point. You can also sew the ring directly to the body if you prefer a more secure attachment — just pass a piece of yarn through the ring and stitch it firmly to the base of the mouse.

If you want to use the mouse as an ornament instead of a keychain, attach a small loop of ribbon or a piece of thin cord to the top of the head between the ears. This looks especially lovely at Christmas when the mouse is made in white with a red nose and a tiny felt Santa hat.

Tips for the Best Results

There are a few things I’ve learned over many rounds of mouse-making that will genuinely make your finished project look better.

Use a tighter gauge than you think you need. If your fabric is too loose, the stuffing will show through the stitches and the mouse will have a lumpy, uneven appearance. Going down a needle size is almost always the right call for amigurumi-style knitting.

Don’t overstuff. A firmly but moderately stuffed mouse keeps its shape beautifully. An overstuffed mouse ends up looking more like a sphere, and the stitches stretch in a way that’s hard to reverse. Stuff gradually as you close up the body.

Take your time with the face. The positioning of the eyes and nose dramatically changes the expression and personality of your mouse. Try placing them with pins before committing to stitching. Move them around. Trust your instincts. A mouse with eyes set slightly closer together looks sweet and innocent; wider-set eyes give a more surprised expression. It’s completely up to you.

Use quality yarn for durability. Since this will be hanging on your keychain and getting regular handling, a yarn that’s slightly more durable — wool, wool blend, or even cotton — will hold up better over time than something very soft and loosely spun. Superwash wool is a wonderful choice since you can toss the whole mouse in the wash if it gets grubby.

Match your yarn needle to your yarn. A tapestry needle with a blunt tip is ideal for sewing on the ears and weaving in ends without splitting the yarn of the body.

Variations and Ideas

One of my favorite things about this pattern is how easily it adapts to different occasions and uses.

For Christmas, make the mouse in white with a tiny red scarf made from a thin ribbon, or dress it up as an elf with green yarn and a little felt hat. A whole cluster of mouse ornaments on a tree is genuinely magical.

For gifts, tuck a mouse into a card or a gift bag. They’re particularly sweet for children (just omit the whiskers and use safety eyes set well before finishing), though I’ve also met many adults who collect them.

For wedding favors, small grey or cream mice with a tiny embroidered heart on the body are unexpectedly sweet and much more personal than a standard favor.

For a cat toy, make the mouse with catnip stuffed inside instead of polyfill. Your cat will be absolutely beside themselves.

You can also leave the keychain ring off entirely and make a bowl of mice — a little pile of different-colored knitted mice in a basket or bowl is one of those charming home décor touches that makes any crafty space feel warm and personal.

Caring for Your Mouse Keychain

If your mouse is made from superwash wool or cotton, you can hand-wash it in cool water with a gentle soap and lay it flat to dry. Reshape while damp if needed. If it’s made from regular wool, spot-clean only to avoid felting. Acrylic yarn is the most washable option and holds up very well over time if your mouse will be subject to heavy daily use on a keychain.

Over time, the nose and eye stitches may loosen slightly with handling. Just re-stitch them with a fresh thread when needed — it only takes a minute and the mouse will look as good as new.

A Few Final Thoughts

I hope you love this tiny mouse pattern as much as I do. It’s one of those designs that seems almost too simple until you finish it and hold it in your hand, and then it just makes you smile. There’s real joy in making something this small and sweet, and there’s even more joy in watching someone else’s face light up when you give one away.

If you make your own mouse keychain, I would absolutely love to see it. Tag your photos with #cherytinyhouse or leave a comment below — seeing your finished mice genuinely makes my day.

Happy knitting, and may your tension be even and your yarn never tangle.
