Cute Boba Tea Keychain Crochet Pattern | Easy Amigurumi DIY

If you’ve been scrolling through craft fairs, Etsy shops, or your favorite Pinterest boards lately, you’ve probably noticed that boba tea everything is having a major moment. And honestly? We’re completely here for it. There’s something undeniably charming about the chubby little cups, the colorful tapioca pearls, and those iconic wide straws that makes boba tea one of the most beloved subjects for handmade crafts. Today we’re combining two of the coziest hobbies around — crocheting and amigurumi — to create the most adorable boba tea keychain you’ve ever seen.

This pattern is beginner-friendly, works up in just an hour or two, and makes an absolutely perfect gift for the boba lover in your life (or, let’s be honest, for yourself). Whether you attach it to your backpack, your keys, your tote bag, or your lanyard, this tiny crocheted cup is going to get compliments everywhere it goes. Let’s dive in.

What Is Amigurumi?

Before we get into the pattern itself, let’s take a quick moment to talk about amigurumi for anyone who is new to the term. Amigurumi is the Japanese art of knitting or crocheting small stuffed animals or characters. The word itself combines the Japanese words “ami,” meaning knitted or crocheted, and “nuigurumi,” meaning stuffed doll. The style originated in Japan and has spread around the world thanks to its irresistible cuteness factor — think big round heads, tiny bodies, and sweet little faces.

Amigurumi projects are typically worked in continuous rounds (also called the magic ring or spiral method) rather than joined rounds, which gives them that smooth, seamless appearance. They’re stuffed with polyfill and usually feature safety eyes, though embroidered eyes are a great alternative for items intended for small children. The boba tea keychain we’re making today uses all of these classic amigurumi techniques, scaled down to keychain size.

Materials You’ll Need

Gathering your supplies before you start is always a good idea. Here’s everything you’ll need to make this boba tea keychain crochet pattern:

Yarn: Worsted weight yarn (size 4) works beautifully for this project, though you can also use DK weight for a slightly smaller finished piece. You’ll need a small amount — we’re talking about 20 yards or less — so this is a fantastic stash buster. Choose a color that resembles your favorite boba flavor. A warm tan or beige for classic milk tea, a soft purple for taro, pale pink for strawberry, or a muted green for matcha all look stunning.

Hook: A 3.5mm or 4mm crochet hook. Go with the smaller hook if you want a tighter stitch that holds its stuffing in more securely, which is especially important for a keychain that will get a lot of handling.

Additional yarn colors: You’ll need a contrasting color for the straw (usually white, clear, or a bright color), and a dark brown or black for the tapioca pearls. A small amount of white or cream for the cup detail is also helpful but optional.

Stuffing: A small amount of polyfill stuffing. You really don’t need much — just enough to give your little cup a satisfying chubby shape.

Safety eyes: 6mm safety eyes work well for this size. If you prefer, you can embroider the face using black yarn or embroidery floss.

Keychain ring or lobster clasp: A small split ring or lobster clasp hardware piece will let you attach your finished amigurumi to your bag, keys, or wherever your heart desires.

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

Scissors: Any pair will do.

Stitch marker: This helps you keep track of the beginning of each round in continuous amigurumi crochet.

Optional: Pink or rosy embroidery floss for adding blush cheeks, which adds an extra dose of sweetness.

Abbreviations and Stitches Used

This pattern uses US crochet terminology. Here’s a quick reference for the abbreviations you’ll encounter:

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 and complete as one single crochet)
st(s) — Stitch(es)
BLO — Back loop only
FLO — Front loop only
PM — Place marker
MR — Magic ring

Pattern Notes

This pattern is worked primarily in continuous rounds. Do not join or turn unless specifically instructed. Move your stitch marker up at the beginning of each round to help you keep your place.

The finished keychain measures approximately 2.5 to 3 inches tall (not including the straw), which is the perfect size for a keychain charm. If you want it slightly larger, simply size up your yarn and hook.

When stuffing, aim for firm but not overstuffed. You want the cup to hold its shape without distorting the stitches.

The Boba Tea Keychain Crochet Pattern

Part One: The Cup Body

The cup is the main piece of the amigurumi and the largest section. We’ll work from the bottom up.

Round 1: MR, 6 sc into the ring. (6 sts)

Round 2: Inc in each st around. (12 sts)

Round 3: Sc 1, inc repeat around. (18 sts)

Round 4: Sc 2, inc repeat around. (24 sts)

Round 5: Sc 3, inc repeat around. (30 sts)

Rounds 6 through 10: Sc in each st around. (30 sts) — This creates the main body of the cup. Work these 5 rounds straight without any increases or decreases.

Round 11 (BLO): Sc in back loop only in each st around. (30 sts) — Working in the back loop only here creates a slight ridge that mimics the rim detail often seen on boba cups.

Rounds 12 and 13: Sc in each st around. (30 sts)

Round 14: Sc 3, dec repeat around. (24 sts)

Before you continue, this is a good moment to attach your safety eyes if you’re using them. Position them between rounds 8 and 9, about 6 to 8 stitches apart. If you’re adding blush cheeks, you can do that with embroidery floss once the piece is complete.

Round 15: Sc 2, dec repeat around. (18 sts)

Begin stuffing your cup firmly but not tightly. Continue adding stuffing as you work the next round.

Round 16: Sc 1, dec repeat around. (12 sts)

Round 17: Dec around. (6 sts)

Close the top by weaving your yarn tail through the remaining 6 stitches and pulling tight. Fasten off and weave in the end.

Part Two: The Cup Sleeve (Optional but Adorable)

Many boba shops put their drinks in cups with little paper sleeves or branded holders. Adding a small sleeve to your crochet cup is an easy way to add a realistic detail and a pop of contrasting color.

Using a contrasting yarn color, join with a sl st to one of the front loops you left exposed in Round 11.

Round 1 (FLO of Round 11): Sc in the front loop of each stitch from Round 11 all the way around. (30 sts)

Rounds 2 and 3: Sc in each st around. (30 sts)

Sl st to join, fasten off, and weave in the end. This creates a small ribbed band around the middle of the cup that looks just like a cup sleeve.

Part Three: The Tapioca Pearls

What’s a boba tea without the boba? These tiny round balls are crocheted separately and either attached to the top of the cup or embroidered on as dots, depending on your preference. Making three-dimensional pearls takes a bit more time but looks absolutely darling peeking out from the top of the cup.

For each pearl (make 3 to 5):

Round 1: MR, 6 sc. (6 sts)
Round 2: Inc in each st. (12 sts)
Round 3: Sc in each st. (12 sts)
Round 4: Dec around. (6 sts)

Stuff lightly, close, and fasten off leaving a tail for sewing.

Sew the pearls to the top of the cup in a cluster, nestled together to look like they’re peeking out over the rim. Use your tapestry needle and a length of the same yarn to secure each pearl firmly.

If tiny 3D pearls feel too fiddly, simply embroider 3 to 5 small circles or French knots at the top of the cup using dark brown yarn. This is a completely valid shortcut and still looks adorable.

Part Four: The Straw

The straw is probably the most recognizable feature of a boba tea — that wide, extra-thicc straw designed to let the tapioca pearls slide right through. For crochet purposes, we’ll make a simple tube.

Using white, cream, or a bright accent color:

Round 1: MR, 4 sc. (4 sts)
Rounds 2 through 12: Sc in each st around. (4 sts)

Fasten off, leaving a long tail. Do not stuff the straw. Use your tapestry needle to sew the bottom of the straw securely to the top of the cup, positioned slightly off-center to one side for a realistic look.

Part Five: Adding the Keychain Hardware

Now for the finishing touch that transforms your amigurumi into a wearable accessory.

Before you completely close the top of your cup, or alternatively by threading through a secure stitch at the very top of the cup, you’ll attach your keychain loop. The easiest method is to cut a short piece of yarn (about 4 inches), fold it in half, thread the folded end through a stitch at the top of the cup using your tapestry needle, and then pass the two loose ends through the folded loop and pull tight to create a lark’s head knot. Thread a split ring through this loop, and you’re done.

Alternatively, you can use a short length of jewelry chain between the yarn loop and the keychain ring for a slightly more polished, store-bought look.

Finishing Touches

Take a moment now to look over your little boba cup and tidy up any loose ends. Weave in all your yarn tails securely — this is extra important for a keychain, since it will get a lot of tugging and pulling during everyday use. Give all your sewn-on pieces (pearls, straw) a gentle tug to make sure they’re secure.

If you want to add blush cheeks, use a small amount of pink or rose embroidery floss to make a few horizontal satin stitches in a small oval shape on each cheek, positioned just below and outside each eye. This tiny detail makes your amigurumi look incredibly sweet and gives it that signature kawaii aesthetic.

You can also use a fine permanent marker or fabric paint to add additional details like a logo on the cup sleeve, small hearts, or the word “boba” in tiny letters.

Tips for Making This Pattern Even Cuter

There are so many ways to customize this basic pattern and make it your own. Here are a few ideas to get your creative juices flowing.

Color variations: Try a deep brown base color for chocolate boba, a dusty pink for strawberry milk tea, or a soft sage green for a matcha latte version. The beauty of amigurumi is that a simple color swap completely transforms the character.

Add a face: Beyond just the eyes, you can give your boba a little smile using a short length of black yarn or embroidery floss, stitched in a gentle curve between the eyes. Adding tiny eyebrows in a surprised or happy expression cranks the cuteness factor up to eleven.

Make a set: These little cups work up so quickly that you might want to make a whole collection in different flavors to give as a gift set. Packaging several in a small box with a handwritten note is one of the most charming handmade gift ideas you can put together.

Vary the size: Try using fingering or lace weight yarn with a 2mm hook to make a micro-sized keychain, or use bulky weight yarn with a 6mm hook for an oversized plushy version that’s more of a desk companion than a keychain.

Seasonal spins: Around the holidays, you could make an eggnog boba in cream and gold, or a peppermint version in red and white stripes with a candy cane straw.

Gifting and Displaying Your Boba Keychain

This pattern is genuinely one of the most giftable crochet projects out there. The materials cost next to nothing if you’re working from your stash, the finished piece is compact and lightweight, and just about everyone seems to love boba tea these days. Consider gifting these to friends for birthdays, as party favors at a boba-themed party, as stocking stuffers, or as a sweet “just because” present.

For craft fairs and markets, these little keychains are consistently popular and quick to make in batches. If you’re looking for a small-scale item to sell at a local market or on an online shop, boba tea keychains photograph beautifully — especially when styled on a flat lay with actual boba tea cups, soft-colored fabric backgrounds, or alongside matching crocheted accessories.

If you make a set for your own use, consider making a coordinating set for your backpack and your keys so your whole carry matches. You could even add other crocheted charms — small macarons, tiny cats, little hearts — and attach them all to a single ring for a charm cluster that’s entirely handmade.

Caring for Your Crocheted Keychain

Since this little guy is going to live on your keys or bag, it’s going to encounter the real world: the inside of purses, rainy days, and the occasional spill. Here’s how to keep it looking fresh.

For spot cleaning, simply dab the affected area gently with a damp cloth and a tiny drop of mild soap, then let it air dry completely before using. Avoid soaking the keychain since the stuffing inside can take a long time to dry and may develop an unpleasant smell if not dried thoroughly.

If your keychain gets flattened with use, you can gently reshape it by rolling it between your palms and letting it air out in a warm, dry spot.

If the yarn starts to look pilled or fuzzy over time, a small fabric shaver can be used very carefully to remove pilling and freshen up the texture.

Why Crochet Keychains Are Worth Making

In a world of mass-produced accessories, there is something deeply satisfying about carrying something handmade. A crocheted keychain like this one represents hours of skill-building, creativity, and intentionality — even if it only takes you a couple of hours to make. Every stitch was placed by your hands, and that means something.

Beyond the sentimental value, crocheting small accessories is one of the best ways to practice your foundational amigurumi skills. Working in the round, increasing and decreasing smoothly, stuffing, and sewing pieces together are all techniques that you’ll use in every amigurumi project you ever make. A boba tea keychain is the perfect training ground before you tackle a larger stuffed animal or character.

And practically speaking, having a handmade keychain means you’ll always be able to spot your keys in the bottom of your bag immediately. That alone might be worth the yarn.

Final Thoughts

Whether you’re a seasoned crocheter looking for a quick and satisfying project or a beginner dipping your toes into the world of amigurumi, this cute boba tea keychain crochet pattern is a wonderful place to start. It uses just a handful of basic stitches, comes together quickly, and delivers maximum cuteness for minimal effort. The fact that it’s functional and wearable is just the cherry on top — or in this case, the tapioca pearl at the bottom of your cup.

Don’t forget to tag your finished boba keychains on social media so other makers can see your color choices and customizations. The crochet community is endlessly inspiring, and there’s a good chance your taro-purple keychain or your matcha-green version will give someone else exactly the color inspo they needed. Happy
