A tiny cup of bubble tea, a handful of colorful crochet stitches, and a cute little face can turn an ordinary keychain into something seriously adorable. This cute crochet bubble tea keychain pattern creates a miniature boba drink that you can attach to your keys, backpack, purse, or crochet project bag.

The best part? You don’t need advanced crochet skills or a mountain of supplies. You’ll work with basic stitches, a little stuffing, and a few simple color changes to create a tiny cup with a creamy drink, dark tapioca pearls, and a hanging loop.

If you’ve ever wanted to make a small crochet gift without spending an entire weekend on it, this pattern deserves a spot on your project list. Let’s make a miniature boba cup that looks cute enough to order another drink.

Materials

• Main cup yarn: Cream, white, pale pink, or light brown.
• Lid yarn: Dark brown, pink, green, or another contrasting color.
• Boba pearl yarn: Dark brown or black.
• Straw yarn: Pink, green, yellow, or your preferred color.
• Crochet hook: 2.0–2.5 mm.
• Stuffing: A small amount of polyester fiberfill.
• Yarn needle: For sewing the pieces together.
• Stitch marker: To mark the beginning of each round.
• Scissors: For trimming yarn ends.
• Safety eyes: Optional, around 5–6 mm, or black embroidery thread.
• Keychain hardware: A small metal ring or lobster clasp.

Gauge & Stitch Pattern

Stitch pattern

The cup uses basic single crochet stitches worked in continuous spiral rounds. You’ll begin at the bottom, increase to form the base, work several rounds without increases to create the sides, and then shape the top.

The lid uses a small flat crochet circle, while the straw uses a narrow tube or folded strip. You can crochet the boba pearls separately or embroider them directly onto the cup.

Skill Level – Confident beginner

You should understand these techniques:

• Making a magic ring.
• Crocheting single crochet stitches.
• Increasing stitches.
• Decreasing stitches.
• Working in continuous rounds.
• Sewing small crochet pieces together.
• Weaving in yarn ends.

Notes Before You Start

A few small details make a noticeable difference in amigurumi. Keep these tips in mind while working through the pattern.

• Crochet in continuous rounds unless the instructions tell you to join a round.
• Place a stitch marker in the first stitch of each round so you don’t lose track.
• Use tight, even stitches to prevent the stuffing from showing.
• Stuff the cup gradually instead of adding all the filling at once.
• Keep your yarn tails long enough for sewing.
• Count your stitches after every round, particularly after increases and decreases.

The cup uses single crochet stitches to create a firm fabric. If you normally crochet loosely, try a smaller hook before changing your yarn.

One important detail: don’t overstuff the cup. Too much filling can stretch the stitches, distort the shape, and make the keychain look lumpy. A little stuffing goes a long way in miniature amigurumi.

Cute Crochet Bubble Tea Keychain Pattern

Crochet the Cup

Choose your main drink color. Cream works well for milk tea, pink gives you strawberry boba, and pale green creates a matcha-inspired drink.

Work in continuous rounds.

Rnd 1: Make a magic ring and crochet 6 sc into the ring. (6)

Rnd 2: Inc in each stitch around. (12)

Rnd 3: Repeat sc 1, inc around. (18)

Rnd 4: Repeat sc 2, inc around. (24)

Rnd 5: Repeat sc 3, inc around. (30)

These five rounds form the bottom of your cup. You should have a flat, circular base.

Rnd 6: Crochet 30 sc in BLO. (30)

This round creates a subtle edge that helps distinguish the base from the cup’s sides.

Rnd 7–13: Crochet 30 sc around. (30 each round)

Continue working evenly to build the cup walls. Adjust the number of rounds if you prefer a taller or shorter drink.

Rnd 14: Repeat sc 3, dec around. (24)

Rnd 15: Crochet 24 sc around. (24)

The decrease round gently narrows the upper edge. It gives the cup a slightly tapered shape rather than making it look like a straight cylinder.

Add a small amount of stuffing through the opening. Push the filling into the bottom first, then distribute it around the sides. Keep the upper edge accessible so you can attach the lid.

Fasten off, leaving a long yarn tail for sewing.

Crochet the Lid

Use a contrasting color such as dark brown, pale pink, or matcha green.

Rnd 1: Make a magic ring and crochet 6 sc into it. (6)

Rnd 2: Inc in every stitch around. (12)

Rnd 3: Repeat sc 1, inc around. (18)

Rnd 4: Repeat sc 2, inc around. (24)

Rnd 5: Repeat sc 3, inc around. (30)

Rnd 6: Crochet 30 sc in BLO. (30)

Rnd 7: Crochet 30 sc around. (30)

Fasten off and leave a long sewing tail.

Place the lid over the cup opening. The lid should cover the upper edge without stretching excessively. Add or remove stuffing as needed before sewing the lid securely to the cup.

If the lid looks too wide, use fewer increase rounds. If it looks too small, add another increase round only if the cup’s opening can accommodate it.

Make the Straw

Choose a bright color that contrasts with the lid. A pink straw looks lovely on a cream-colored drink, while a green straw works well with a brown sugar cup.

Rnd 1: Make a magic ring and crochet 5 sc into it. (5)

Rnd 2–5: Crochet 5 sc around. (5 each round)

Fasten off, leaving a long tail.

Lightly fill the straw with a tiny amount of stuffing if you want it to hold a rounded shape. Flatten the bottom edge slightly so you can sew it securely to the lid.

Position the straw near the back or center of the lid. Sew around its base with small, tight stitches.

If you’d rather avoid stuffing such a tiny piece, crochet a short flat strip, fold it into a narrow tube, and sew the edges together. The tube method works well when you want a slimmer straw.

Add the Boba Pearls

The tapioca pearls give the drink its recognizable bubble tea appearance. Use dark brown or black yarn to create small round accents.

You have two options.

Option A: Embroidered pearls

Use dark yarn and a yarn needle to create several small dots across the lower half of the cup. Make each dot with a few short stitches in the same area.

This method keeps the surface smooth and prevents the pearls from snagging on keys or bag straps.

Option B: Mini crochet pearls

Make a magic ring and crochet 4 sc into it. Pull the ring closed, then slip stitch or fasten off. Make several tiny pearls and sew them onto the front of the cup.

Keep the pearls relatively small and space them unevenly for a playful appearance. You don’t need to cover the entire cup. A neat cluster near the bottom often looks more balanced than dozens of dots scattered everywhere.

For a keychain that gets heavy everyday use, I recommend securely embroidered pearls or firmly sewn mini pearls rather than loose decorative pieces.

Add a Cute Face

A kawaii face can turn a simple drink into a character.

Place two black safety eyes on the front of the cup, leaving enough space between them for a small smile. Check the position before attaching the backs of the eyes.

Safety note: If you plan to give the keychain to a young child, skip safety eyes and use securely embroidered facial features instead. Small hardware and decorative pieces can present a choking hazard.

Use black embroidery thread to create a short curved smile. You can add tiny pink cheek marks with pink yarn for an extra cute touch.

Keep the facial features centered above the boba pearls. This placement helps the design look intentional rather than crowded.

Attach the Keychain Hardware

Your bubble tea cup needs a secure connection to its keychain ring.

Use a metal keychain ring, lobster clasp, or short chain. Attach the hardware through a sturdy point near the back of the lid or through a reinforced crochet loop.

To make a crochet loop, chain 8–12 stitches, depending on the size of your hardware. Slip stitch back into the starting point to create a small loop, then sew it firmly to the top of the cup.

Reinforce the connection with several passes of strong yarn. Don’t rely on a single stitch, especially if you plan to attach the charm to a heavy bunch of keys.

Give the loop a gentle tug before using the keychain. It should stay firmly attached without pulling the lid out of shape.

Assembly & Finished Size

Assembly checklist

1. Shape the cup: Adjust the stuffing until the base looks flat and the sides look even.
2. Secure the lid: Sew around the opening, distributing the stitches evenly.
3. Attach the straw: Position it upright and reinforce the base.
4. Add the pearls: Keep them close to the lower half of the cup.
5. Embroider the face: Check the alignment before securing the final stitches.
6. Attach the hardware: Reinforce the loop and trim any loose ends.

The finished cup should measure approximately 5–6 cm tall, with a total height of 7–9 cm including the straw. The metal keychain hardware adds a little extra length.

Finished Size

The finished cup should measure approximately 5–6 cm tall, with a total height of 7–9 cm including the straw. The metal keychain hardware adds a little extra length.

Conclusion

cute crochet bubble tea keychain pattern gives you a simple way to turn a few yarn scraps into a tiny, colorful accessory. The rounded cup, contrasting lid, little straw, and dark boba pearls create the familiar bubble tea look, while the optional face adds a cheerful personality.

Keep your stitches tight, count your rounds carefully, and reinforce the keychain loop before attaching the hardware. Those small details help your finished charm look tidy and hold up to everyday use.

Once you’ve made your first cup, experiment with strawberry pink, matcha green, lavender, or classic caramel colors. You can even create an entire collection of miniature drinks for your bag or as handmade gifts.

FAQ

My cup looks wavy at the bottom

Your base may contain too many or too few stitches. Check the stitch count after every increase round and make sure you followed the pattern accurately.

If your base still curls despite the correct count, try a different hook size or adjust your tension.

Stuffing shows through the stitches

Use a smaller hook and crochet with slightly tighter tension. Add stuffing gradually rather than forcing a large amount through the opening.

A firm fabric will help the cup keep its shape without exposing the filling.

The lid doesn’t fit the cup

Compare the stitch count around the cup opening with the lid’s circumference. Your tension may have changed between the two pieces.

If the lid sits too loosely, remove a round or adjust the number of increases. If it looks too tight, add a small amount of circumference to the lid.

The straw keeps falling over

Check the attachment point and sew through several stitches at the base of the straw. You can also add a tiny amount of stuffing to help the straw retain its shape.

Avoid making the straw excessively tall. A shorter straw creates less leverage and puts less strain on the seam.

The finished keychain looks uneven

Inspect the face, pearls, and straw placement before changing the cup itself. Sometimes the body looks uneven simply because one decorative element sits too far to one side.

Use stitch markers or pins to test the layout before sewing everything permanently.
