This crochet boba tea keychain turns a tiny crocheted cup into a fun amigurumi accessory with a separate lid, straw, six boba pearls, and a simple face. The project is worked in several small components and then assembled into a compact drink-inspired keychain or bag charm.

The finished piece is approximately 3–4 inches tall, including the straw and attachment loop. Final size can vary with yarn, hook size, tension, stuffing, and individual crochet technique.

Project Overview

What You’ll Make

You’ll crochet a miniature boba tea cup from separate components:

1 cup body
1 lid
1 straw
6 boba pearls
1 crochet attachment loop
2 optional safety eyes
1 embroidered mouth

The cup is worked in continuous rounds, while the smaller pieces are crocheted separately and sewn into place during assembly.

Before You Start

Work in Continuous Rounds

The cup body, straw, and boba pearls are worked in continuous rounds. A stitch marker can help you keep track of the beginning of each round.

Count Your Stitches

The shaping depends on precise increases and decreases. If your stitch count is off, correct it before continuing to the next round.

Stuff as You Go

Add stuffing gradually during the closing rounds of the cup and boba pearls. Avoid overstuffing, which can stretch the stitches and distort the shape.

Shape Before Sewing

Take a moment to adjust the shape of each stuffed component before closing it completely or sewing it to another piece.

Construction Order

The main pieces are crocheted separately before assembly:

Cup
Lid
Straw
Six boba pearls
Facial details
Keychain attachment loop

Facial Details

Eyes

Use two 6 mm safety eyes or embroider the eyes with black thread.

Place the eyes symmetrically on the front of the cup, above the main group of boba pearls. Because exact eye spacing has not been physically tested, use visual symmetry and the available front surface as your guide.

Mouth

Using black embroidery thread, add a small smile centered below the eyes and above the main boba area.

Assembly

Step 1: Attach the Lid

Center the finished lid over the top of the cup.

Use the lid’s long sewing tail to attach the edge securely around the upper portion of the cup. Check that the lid sits evenly before completing the seam.

Step 2: Add the Boba Pearls

Arrange the six boba pearls across the front of the cup.

A balanced arrangement can use:

Three pearls across the lower front
Two pearls above them
One pearl slightly offset near the center

Adjust the arrangement visually before sewing the pearls permanently into place.

Step 3: Add the Facial Features

Once the boba pearls are positioned, add the eyes to the open area above them.

Compare both sides before permanently securing the facial details.

Embroider the mouth below the eyes.

Step 4: Attach the Straw

Position the straw toward the rear portion of the lid so it remains visible without covering the face.

Sew the flattened lower end securely to the lid.

Step 5: Add the Keychain Loop

Chain 8 in the lid or main cup color.

Slip stitch into the starting point to form a small loop.

FO, leaving a long sewing tail.

Place the loop at the rear center of the lid/top area.

For additional reinforcement, sew the loop through both the lid and the upper portion of the cup rather than attaching it to the lid alone.

Make several reinforcing passes through the attachment point.

Finishing

Before attaching keychain hardware, inspect the finished piece carefully.

Check that:

The cup holds its shape.
The lid is securely attached.
The straw is firmly sewn.
All six boba pearls are secure.
The face looks balanced.
No stuffing is visible.
Loose yarn ends are woven in.
The attachment loop is reinforced.

The attachment loop has been designed to provide a reinforced connection point, but its long-term durability has not been physically tested.

Helpful Tips

Keep Your Tension Consistent

Consistent tension helps the cup maintain a smooth shape and keeps the stitches compact.

Stuff Gradually

Small amounts of stuffing are easier to control than adding a large amount at once. Shape the cup as you go.

Count Before Moving On

The shaping rounds depend on the stated stitch counts. If your count is different, stop and identify the mistake before continuing.

Compare Symmetrical Details

For the eyes and other paired details, compare both sides before making the placement permanent.

Reinforce the Attachment Point

Because the keychain loop will experience handling, use multiple sewing passes through the loop, lid, and upper cup area.

Troubleshooting

My Cup Looks Too Loose

Check your crochet tension. Looser stitches may make the stuffing more visible and can create a softer, less defined shape.

My Cup Looks Lumpy

Try redistributing the stuffing instead of adding more. Uneven filling can change the silhouette.

My Lid Does Not Sit Evenly

Before completing the seam, reposition the lid around the top of the cup so the edge is distributed evenly.

My Face Looks Off-Center

Use the cup’s front surface as your guide and compare the two eyes visually before sewing them permanently.

My Boba Pearls Look Uneven

Arrange all six pearls before attaching them. Move them around until the overall composition looks balanced.

My Keychain Loop Feels Loose

Reinforce the loop through the lid and upper cup area with several sewing passes. Since the pattern has not been physically tested, inspect the attachment carefully before regular use.

Customization Ideas

Change the Drink Color

Swap the main cup color for pink, lavender, green, cream, or another drink-inspired shade.

Changing the main color does not require changing the cup’s stitch structure.

Change the Face

Keep the face simple with safety eyes and an embroidered smile, or embroider the eyes instead.

Use It as a Bag Charm

The finished crochet drink can also be adapted for use as a bag charm by connecting suitable hardware to the reinforced crochet loop.

Care

Care should follow the instructions appropriate for the yarn used.

For a handmade piece with crocheted details and attached hardware, gentle handling is preferable to aggressive cleaning or pulling.

Frequently Asked Questions

How long does this project take?

A tested completion time has not been established. The actual time will vary depending on crochet speed, tension, experience with amigurumi, and the amount of sewing and finishing involved.

Can I use different yarn colors?

Yes. The cup and straw colors can be changed without altering the stitch structure. Different yarn weights can affect the finished size and proportions.

Can I make the face without safety eyes?

Yes. The eyes can be embroidered with black thread instead of using safety eyes.

Is it sturdy enough for keys?

The pattern includes a reinforced attachment loop sewn through the lid and upper cup area. However, the finished keychain has not been physically tested for load or long-term durability, so its durability should not be guaranteed.

Can children help with this project?

Children may be able to participate in age-appropriate crochet or supervised crafting activities. Safety eyes are small parts and can present a choking hazard, especially for children under 3.

How should I clean the finished keychain?

Follow the care recommendations for the yarn used. Gentle cleaning and handling are preferable for a handmade piece with attached details and hardware.

Can I change the size?

Changing yarn weight or hook size may change the finished size, but the resulting proportions have not been physically tested with this pattern.
