Materials You Will Need
Before you pick up your hook, gather your supplies. The beauty of a miniature amigurumi project like this one is that you do not need a lot of yarn or expensive tools. You likely already have most of what you need in your craft stash.
Yarn: You will need a small amount of worsted weight yarn in your chosen rat color. Classic options include light gray, brown, black, cream, or even pink for an albino rat look. You will also need a tiny bit of pink yarn for the inner ears and the nose, and white or cream for the tummy if you want to add that detail.
Hook: A 2.5mm or 3.0mm crochet hook works well for amigurumi at this scale. If your tension runs loose, go down a hook size to keep your stitches tight and prevent the stuffing from showing through.
Stuffing: Polyester fiberfill stuffing is the standard choice. You only need a small pinch for a project this tiny.
Safety eyes: Two 4mm or 6mm black safety eyes. If you are making this for a young child, use black embroidery thread to stitch eyes instead, since safety eyes are a choking hazard for little ones.
Wire keychain ring or split ring: To attach your finished rat to a keychain, bag, or zipper pull. You can find these at any craft store or order them in bulk online very affordably.
Jump ring and lobster claw clasp (optional): For a more polished bag charm finish.
Yarn needle: For weaving in ends and sewing pieces together.
Stitch markers: Helpful for keeping track of rounds in amigurumi work.
Wire (optional): A short piece of thin floral wire can be threaded through the tail to make it poseable and give it that wonderful curling rat tail look.
Abbreviations and Stitches Used
This pattern uses standard US crochet terminology.
MR — Magic ring (also called 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 through front loops of next two stitches, yarn over, pull through both loops, yarn over, pull through remaining two loops)
BLO — Back loop only
FO — Fasten off
All amigurumi rounds are worked in a continuous spiral unless otherwise noted. Do not join at the end of each round unless the pattern specifically instructs you to.
Pattern Notes for Beginners
If you are brand new to amigurumi, a few notes will make your life much easier before you start.
Always crochet tightly. The whole point of amigurumi tension is that your stitches should be snug enough that stuffing does not peek through the gaps. If you can see light through your work when you hold it up, try a smaller hook.
Use a stitch marker in the first stitch of each new round. Since you are working in a spiral, rounds blend into each other seamlessly, and it is very easy to lose your place without a marker. Move your marker up with each new round.
Stuff as you go. For amigurumi, you stuff pieces before closing them off rather than trying to push stuffing in at the very end. Add a little fiberfill when the opening is still wide enough to work with comfortably.
Leave long tails when fastening off. You will need those tails to sew pieces together, so resist the urge to trim everything close to the knot.
Crochet Rat Pattern — Step by Step
The Body
The body is the main piece you will work first. It is worked from the nose end toward the back.
Round 1: Start with a magic ring, sc 6 into the ring. Pull the ring closed. (6 stitches)
Round 2: Inc in each stitch around. (12 stitches)
Round 3: Sc 1, inc repeat around. (18 stitches)
Round 4: Sc 2, inc repeat around. (24 stitches)
Rounds 5–10: Sc in each stitch around. (24 stitches each round)
This gives you a nice oval body that has a slightly tapered nose end. At this point, insert your safety eyes between rounds 3 and 4, with about 4–6 stitches between them. If you are using embroidery thread for eyes, you will add those after stuffing and closing.
Round 11: Sc 2, dec repeat around. (18 stitches)
Add your stuffing now. Pack it firmly but not so hard that the shape distorts. You want a round, plump little body.
Round 12: Sc 1, dec repeat around. (12 stitches)
Round 13: Dec around. (6 stitches)
Fasten off, leaving a long tail. Use your yarn needle to weave the tail through the front loops of the remaining 6 stitches and pull tight to close. Weave in the end.
The Head
Round 1: MR, sc 6. (6 stitches)
Round 2: Inc in each stitch. (12 stitches)
Round 3: Sc 1, inc repeat. (18 stitches)
Round 4: Sc 2, inc repeat. (24 stitches)
Rounds 5–8: Sc around. (24 stitches)
Round 9: Sc 2, dec repeat. (18 stitches)
Stuff the head firmly at this point.
Round 10: Sc 1, dec repeat. (12 stitches)
Round 11: Dec around. (6 stitches)
Close as before. Leave a long tail for attaching to the body. Sew the head to the flat back end of the body, positioning it so the nose tilts slightly upward for that classic curious rat expression.
The Ears (Make 2)
Each ear is made in two layers — an outer ear in your main color and a smaller inner ear in pink.
Outer ear: MR, sc 8, sl st to join. Fasten off, leaving a long tail.
Inner ear: MR, sc 5, sl st to join. Fasten off, leaving a long tail.
Place the inner ear on top of the outer ear and sew around the edges to attach them together, then sew the finished ear to the side of the head. Position the ears roughly between rounds 2 and 4 of the head, spaced evenly apart. A little pinch at the base of each ear before sewing gives them a more natural cupped shape.
The Nose
With pink yarn, embroider a small oval or triangular nose directly onto the tip of the head using a yarn needle and a few satin stitches. Alternatively, you can use a tiny pink seed bead glued in place with fabric glue once everything is assembled.
The Tail
The tail is one of the most distinctive features of your crochet rat. You want it long, slightly tapered, and ideally poseable.
Option 1 — Crocheted tail: Chain 25 or so with a single strand of yarn. Slip stitch back along the chain for a rounded, slightly textured tail.
Option 2 — Twisted cord tail: Cut three strands of yarn each about 30cm long. Hold them together and twist tightly in one direction until they start to coil back on themselves. Fold the bundle in half and allow it to twist together into a cord. Knot one end and trim to neaten. Thread a short piece of thin wire through the center of the twisted cord before knotting if you want a poseable tail.
Sew or knot the tail to the back of the body. Thread it through the closing stitches at the back end and pull through, securing with a knot on the inside before stuffing if you have planned ahead, or sewing it firmly to the outside after assembly.
The Legs and Feet (Optional)
For a keychain size rat, legs are optional and many makers choose to leave them off for a cleaner, rounder look. But if you want to add them, here is a simple approach.
Legs (Make 4): MR, sc 5. (5 stitches)
Rounds 2–4: Sc around.
Fasten off leaving a long tail and stuff very lightly. Sew two legs to each side of the lower body.
The Arms (Optional)
Arms (Make 2): MR, sc 4. (4 stitches)
Rounds 2–3: Sc around.
Fasten off and sew one to each side of the upper body just below the head. You can bend them slightly forward to give the rat a sweet little reaching pose.
Assembling Your Crochet Rat
Once all your pieces are made and you have assembled the main body and head together, step back and look at your little rat from all angles before sewing anything permanently. Placement makes all the difference in amigurumi. Try pinning the ears in a few different spots and holding the tail up in different positions before committing.
When everything looks right, sew each piece firmly using the long tails you left. Go around each attachment point at least twice to make sure nothing pulls loose with wear, since a keychain or bag charm takes more stress than a display piece sitting on a shelf.
Once assembled, trim any remaining yarn tails close to the body and tuck the knots inside if possible.
Attaching Your Keychain Hardware
Thread a keychain ring or split ring through the top of your rat’s head or through a small loop you have crocheted and sewn on at the top. If you want a bag charm style attachment with a clasp, use a jump ring to connect your split ring to a lobster claw clasp. This makes it easy to clip your rat onto any bag strap, zipper pull, or keyring without permanently tying it to one place.
If you want the rat to be attached by its tail instead of its head, you can loop the keychain hardware through the end of the tail for a different hanging orientation.
Color and Customization Ideas
One of the most enjoyable parts of making a crochet rat pattern like this is how easily you can customize it. Here are some ideas to get your creative wheels turning.
A soft gray rat with a pink nose and pale belly yarn looks incredibly realistic and is always a crowd favorite. A warm brown rat reminds many people of a cozy little wild mouse. A stark black rat with red embroidered eyes looks theatrical and makes a wonderful Halloween or gothic accessory. A white or cream rat with pink eyes (using pink safety eyes or embroidery) is a perfect nod to the sweet albino pet rats that so many people adore. You can even go full fantasy and make a lavender rat or a teal one — amigurumi does not have to follow the rules of nature.
Adding a tiny crocheted accessory takes your rat to the next level. A minuscule crocheted bow tied between the ears, a tiny scarf made from a short length of ribbon, or even a little crocheted hat turned to sit jauntily on one ear can make your rat feel like a full character rather than just a charm.
Tips for Making Multiple Rats as Gifts or for Craft Fairs
If you are planning to make a batch of these little crochet rat bag charms for a craft fair, a gifting occasion, or because you simply cannot stop once you start (a very real risk), a few batch-making tips will save you time and energy.
Make all the bodies first in an assembly line, then all the heads, then all the ears. This way you stay in a rhythm with each stitch pattern and work much faster than you would if you made one complete rat at a time.
Prepare your hardware in advance. Pre-open your split rings or jump rings so you are not wrestling with them when your hands are already tired from crocheting.
Keep a small basket or container for each rat as it comes together so pieces do not get mixed up or lost.
If you are selling these, a simple card backing with a safety pin or a small hang tag adds a professional, polished look that elevates the perceived value of your handmade work considerably.
Storing and Caring for Your Crochet Rat
Amigurumi made with acrylic yarn can be gently hand-washed in cool water with a small amount of mild soap. Press out excess water gently without wringing, reshape, and lay flat to dry. Avoid putting safety eyes or glued details near heat or in the dryer.
If your rat lives on a keychain and picks up everyday grime, a quick spot clean with a damp cloth usually does the trick for small marks.
Why Rats Make Such Wonderful Amigurumi Subjects
There is something about a tiny crocheted rat that people absolutely cannot resist. Rats have a complicated reputation in popular culture, but anyone who has ever owned a pet rat knows they are among the most intelligent, affectionate, and curious animals you can share your home with. A beautifully made miniature crochet rat is a subtle way of celebrating that, and it resonates deeply with the rat-loving community.
These little charms also tap into a broader appreciation for the small, the detailed, and the handmade. In a world of mass-produced accessories, a bag charm made by hand — worked stitch by stitch with care and intention — carries a warmth that no factory-made charm can replicate. People notice. They ask where you got it, and when you say you made it yourself, that moment of quiet pride is one of the best things about being a maker.
Whether you are crocheting this rat for yourself, for a friend who loves their pet rats, as a quirky birthday addition, or just because you saw a photo of one and immediately needed to make it, this project is worth every stitch. It is fast, it is fun, and the finished result is undeniably charming.
Now pick up your hook, choose your favorite rat color, and get started. Your tiny crochet rat is waiting to come to life.
Happy crocheting! If you make this pattern, share your finished rats — seeing the different colors, expressions, and creative twists makers put on a pattern is always one of the great joys of the crochet community.
