Crochet Rat Pattern: How to Make an Adorable Little Mouse Keychain and Bag Charm

If you have been looking for the perfect beginner-friendly amigurumi project, you have just found it. This crochet rat pattern walks you through every step of creating a miniature rat that works beautifully as a keychain, bag charm, or handmade gift. Whether you are new to amigurumi or simply love making small, quick projects that come together in an afternoon, this little mouse is going to become one of your favorite go-to patterns.

Rats and mice have had a major moment in the crafting world lately, and honestly, it is easy to see why. They are charming in a quirky, unexpected way. A tiny crocheted rat dangling from your tote bag or house keys is the kind of detail that makes people stop and ask where you got it — and nothing feels better than saying you made it yourself.

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

Why You Will Love This Pattern

This pattern is designed with beginners in mind, but it is genuinely enjoyable for crocheters at any skill level. The finished rat is small enough to work up quickly — most crafters finish theirs in two to three hours — which makes it an excellent choice when you need a last-minute handmade gift or just want the satisfaction of completing something in a single sitting.

The techniques used are the same building blocks you will find in almost every amigurumi pattern: magic rings, single crochets, increases, and decreases. If you already know how to do those things, you are ready to start right now. If some of those terms are new to you, do not worry. Each step is explained clearly as you go.

Materials You Will Need

Before diving into the pattern, gather your supplies. One of the best things about this project is how little you actually need to get started.

Yarn: You will want a fingering weight or sport weight yarn for the body of the rat. DK weight works too if you want a slightly larger finished piece. Classic gray is the most popular choice for an obvious reason, but brown, white, black, and even pastel shades make gorgeous rats. You only need a small amount — roughly 15 to 25 grams — so this is a perfect stash-buster project.

Hook: For fingering or sport weight yarn, a 2.0mm to 2.5mm hook works well. For DK weight, try a 3.0mm hook. Amigurumi generally benefits from going down a hook size or two from the yarn’s recommendation so your stitches are tight and the stuffing does not show through.

Eyes: Safety eyes in 4mm or 6mm work beautifully for the rat’s face. Black gives that classic beady rodent look, but you can also use clear or colored eyes for a more whimsical effect. If you are making this for a young child, embroider the eyes with yarn instead so there is no choking hazard.

Stuffing: A small amount of polyester fiberfill stuffing is all you need. Since the rat is miniature, you will use very little.

Wire (optional): If you want poseable ears or a tail that holds its shape, a small piece of craft wire or pipe cleaner works wonderfully. This is completely optional.

Accessories: A keychain ring, swivel clip, or bag charm hardware to finish the project. You can find these at any craft store or online.

Other tools: Yarn needle for sewing pieces together and weaving in ends, stitch markers to keep track of rounds, and scissors.

Abbreviations Used in This Pattern

Before you begin, here is a quick reference for the abbreviations you will see throughout:

MR — Magic ring
SC — Single crochet
INC — Increase (2 SC in the same stitch)
DEC — Invisible decrease (draw up a loop through the front loops of the next two stitches, yarn over, pull through all loops)
SL ST — Slip stitch
CH — Chain
FO — Fasten off
BLO — Back loops only
St — Stitch
Rnd — Round

The Pattern

Part One: The Body

The body of the rat is worked in continuous rounds from the nose back toward the tail end.

Rnd 1: Start with a MR and work 6 SC into it. Pull the ring closed. (6 sts)

Rnd 2: INC in each stitch around. (12 sts)

Rnd 3: [SC 1, INC] repeat around. (18 sts)

Rnd 4: [SC 2, INC] repeat around. (24 sts)

Rnd 5: SC around. (24 sts)

Rnd 6: SC around. (24 sts)

Rnd 7: SC around. (24 sts)

Rnd 8: [SC 2, DEC] repeat around. (18 sts)

At this point, you are going to begin shaping the body. The piece should look like a small oval capsule. Before continuing, you may want to lightly stuff the front portion of the body so it keeps its round shape as you close up the back.

Rnd 9: [SC 1, DEC] repeat around. (12 sts)

Rnd 10: DEC around. (6 sts)

Add any remaining stuffing now and make sure it is evenly distributed. The rat should feel firm but not overstuffed — you want the stitches to stay flat and even.

Fasten off, leaving a tail for closing. Use your yarn needle to weave through the front loops of the remaining 6 stitches and pull tight to close. Weave in the end.

Part Two: The Head

The head is worked separately and then sewn onto the body.

Rnd 1: MR, 6 SC. (6 sts)

Rnd 2: INC in each stitch around. (12 sts)

Rnd 3: [SC 1, INC] repeat around. (18 sts)

Rnd 4: [SC 2, INC] repeat around. (24 sts)

Rnd 5: SC around. (24 sts)

Rnd 6: SC around. (24 sts)

Rnd 7: [SC 2, DEC] repeat around. (18 sts)

Before closing the head completely, insert your safety eyes between rounds 3 and 4, spaced about 6 to 8 stitches apart. Position them slightly toward the sides of the face for that characteristic rat look. Once the eyes are secure, add stuffing.

Rnd 8: [SC 1, DEC] repeat around. (12 sts)

Rnd 9: DEC around. (6 sts)

Close the same way you closed the body. Leave a long tail for sewing.

Part Three: The Ears (Make Two)

The ears are simple flat circles. You can make them as large or as small as you like depending on whether you want a rat-like look or more of a classic mouse silhouette.

Rnd 1: MR, 6 SC. (6 sts)

Rnd 2: INC in each stitch around. (12 sts)

Rnd 3: Slip stitch in the next stitch to close. Fasten off with a tail for sewing.

For slightly larger ears, add one more round of [SC 1, INC] before the slip stitch to get 18 stitches.

If you want cupped, dimensional ears, simply do not flatten the circle before sewing — let it hold its natural curve.

Part Four: The Tail

The tail is one of those small details that instantly sells the whole piece. There are a few different ways to make it.

Crocheted tail: Chain 20 to 30 stitches (depending on how long you want the tail), then slip stitch back down the chain for a rounded, slightly stiff tail. Fasten off.

Twisted cord tail: Cut three strands of yarn about four times the length you want the tail to be. Knot them at one end, tape that end to a surface, and twist the strands tightly in one direction. Once they are twisted, fold the whole length in half and let it twist back on itself to create a natural cord. Knot the open end. This gives a lovely textured tail.

Wire-wrapped tail: Cut a pipe cleaner or piece of craft wire to your desired tail length and wrap it tightly with yarn, securing the ends with a dab of fabric glue. This version is fully poseable and holds any curve you give it.

Part Five: The Nose and Face Details

Once you have attached the eyes, you can add a little nose with a few stitches of pink or peach yarn. Bring your needle up through the center of the muzzle area at the tip of the head and make two or three small horizontal stitches, then bring the thread down slightly below those stitches to form a small inverted V shape, which creates a nose and the suggestion of a mouth.

You can also embroider small whiskers using a single strand of stiff yarn or even fishing line. Thread your needle through the muzzle from one side to the other, pulling the strand until a short length is left on each side, and tie a small knot to hold it in place.

Assembling Your Crochet Rat

Now comes the fun part — putting all the pieces together.

Start by sewing the head onto the body. Position the head at the rounded front end of the body, making sure it sits centered and slightly tilted upward (this gives the rat a cute alert expression rather than looking like it is staring at the ground). Use the long tail from the head and a yarn needle to sew through the edges of both pieces in small, even stitches. Work all the way around and then pull gently to close any gap. Weave in the end securely.

Next, position the ears on top of the head, roughly at rounds 2 and 3 from the top. You can angle them slightly outward or have them sit more upright depending on the look you are going for. Sew them on firmly. If you have made cupped ears, hold them at a slight angle as you stitch them down so the curve faces forward.

Finally, attach the tail at the very back end of the body. If you are using a crocheted or cord tail, poke the starting end into the last closing point of the body and sew it in firmly. If using a wire tail, fold the very end of the wire over on itself to create a small loop, poke that loop into the body, and stitch it down before weaving in the surrounding yarn to cover the connection point.

Turning Your Rat into a Keychain or Bag Charm

This is what makes this project so practical and giftable. Once your rat is fully assembled, you have a few options for adding the hardware.

Simple loop method: Before you fasten off the body completely, chain 6 to 8 stitches and join them into a small loop with a slip stitch. Fasten off from there. This creates a small yarn loop at the top of the rat’s back through which you can thread a keychain ring or lobster claw clasp.

Sewn-on ring: Use a piece of jump ring hardware and a few stitches of sturdy thread or yarn to attach the ring directly to the top of the rat’s body between the head and body seam. This is a clean look and very secure.

Swivel clip: Swivel clips are especially nice for bag charms because they allow the rat to spin freely, which honestly makes it even more charming in motion. Attach one through your yarn loop or sewn ring and then clip it directly onto a bag strap, zipper pull, or key ring.

Tips for Making the Perfect Miniature Rat

A few small adjustments can make a big difference in how professional your finished rat looks.

Always use a stitch marker to keep track of the beginning of each round. In continuous amigurumi rounds, it is surprisingly easy to lose count, and off-by-one errors can throw off the whole shape of a piece.

Work your stitches firmly and evenly. Amigurumi looks best when the tension is consistent throughout. If you notice your stitches loosening as you go, try consciously slowing down and being more deliberate about pulling each loop through.

Do not overstuff. It is tempting to pack in as much stuffing as possible, but this can actually distort the shape and make the stitches look stretched. Aim for a firm but not taut result — the piece should hold its shape but not be straining at the seams.

When sewing pieces together, take your time. The assembly is often where amigurumi goes from looking handmade to looking truly polished. Small, even stitches that follow the natural lines of the crochet fabric are almost invisible once the yarn is woven in.

Ideas for Personalizing Your Crochet Rat

The basic pattern here is really just a starting point. Once you are comfortable with the shape, there are so many ways to make it your own.

You could dress your rat in a tiny crocheted hat or scarf — small accessories like these are worked in the same basic techniques and add enormous personality. A little bow made from ribbon or yarn can transform the same rat into a sweet feminine version. A tiny piece of craft foam or felt shaped like a wedge of cheese makes a darling accessory to add to the rat’s paws.

Color is another huge variable. A sleek black rat has a completely different personality than a soft lavender one. Gradient or speckled yarn can give the impression of natural fur patterning without any extra technique.

If you want to make a rat family, try making several at different sizes by simply changing your hook and yarn weight. A worsted weight version of the same pattern will come out significantly larger — perfect for a stuffed toy rather than a charm.

This Makes the Most Thoughtful Handmade Gift

There is something genuinely special about giving someone a tiny handmade animal. Unlike a lot of gift options, a crocheted rat keychain is personal, unique, and made with real time and care. It is small enough to ship easily, practical enough to actually use, and quirky enough to be memorable.

These little rats are wonderful for birthdays, holiday stocking stuffers, party favors, craft fairs, and Etsy shops. If you are selling them, they tend to do especially well because they are unusual — most keychain charms at craft fairs look similar, but a tiny crocheted rat immediately catches attention and starts conversations.

They are also a wonderful project to make in multiples once you have the pattern memorized. The second and third ones always go faster than the first, and before long you will have a whole little colony of crocheted rats ready to send out into the world.

A Few Notes on Gauge and Sizing

Since this is a charm rather than a wearable item, gauge is not critical in the strict sense — you are not trying to match a size for fit. That said, the finished rat will be roughly 3 to 4 inches long when made in fingering weight on a 2.25mm hook, and approximately 5 to 6 inches in DK weight on a 3.0mm hook. If you want a truly tiny charm, go down to a laceweight yarn on a 1.5mm or 1.75mm hook. It takes more patience but the result is extraordinarily delicate and impressive.

Final Thoughts

This crochet rat pattern is one of those projects that is easy to underestimate until you finish your first one and immediately want to make five more. It is quick, it is beginner-friendly, it uses very little yarn, and the finished piece genuinely delights everyone who sees it. Whether you are making your first amigurumi or your hundredth, this little mouse keychain and bag charm is worth a place in your project lineup.
