Crochet Baby Bottle Keychain – Free Amigurumi Pattern
There is something undeniably charming about miniature versions of everyday objects, and a crocheted baby bottle keychain is no exception. Whether you want to make a sweet gift for a new parent, a playful addition to a diaper bag, or simply a fun weekend project to add to your amigurumi collection, this tiny bottle packs a lot of personality into just a few inches of yarn. Best of all, it requires only basic crochet skills, a small amount of materials, and a few hours of your time.
This free pattern walks you through every step of creating a baby bottle keychain from scratch, including the body, the nipple top, and the finishing details that make it look just like the real thing. Whether you are a beginner who has just mastered the magic ring or an experienced crocheter looking for a quick and satisfying project, this guide has everything you need.
Why You Will Love This Pattern
Mini amigurumi projects are some of the most satisfying things you can crochet. They work up fast, use almost no yarn, and make incredibly thoughtful handmade gifts. A baby bottle keychain specifically hits a sweet spot between cute and functional. You can attach it to a keychain ring and clip it to a diaper bag, use it as a baby shower party favor, hang it as a gift tag on a wrapped present, or simply display it as a tiny piece of fiber art.
Because this pattern uses only single crochets and increases and decreases, it is an excellent project for newer crocheters who want to practice working in the round without committing to a larger amigurumi figure. At the same time, experienced makers will appreciate how quickly it comes together and how much room there is to personalize it with different colors, yarn weights, and embellishments.
Materials You Will Need
Before you dive into the pattern, gather everything on this list. The beauty of a small project like this is that you can use yarn scraps you probably already have in your stash.
Yarn: Worsted weight yarn (size 4) in white or cream for the bottle body, a soft blue, pink, or yellow for the label section, and a skin-tone or light beige for the nipple. You only need small amounts of each, so this is a perfect stash-buster project.
Hook: A 2.5 mm or 3.0 mm crochet hook works best for creating a tight, dense fabric that holds its shape and does not let the stuffing show through. If you tend to crochet loosely, size down your hook.
Stuffing: Polyester fiberfill stuffing. You only need a small pinch for a project this size, but it makes a big difference in the final shape.
Safety eyes: Two 6 mm black safety eyes if you want to give your bottle a cute character face, though these are entirely optional. Many people prefer to keep the bottle looking realistic rather than adding a face.
Embroidery floss or black yarn: For adding a simple measurement line detail to the side of the bottle or a small smile if you are giving the bottle a face.
Keychain ring: A lobster claw keychain ring or a split ring, available at any craft store or online. You will attach this to the finished piece with a short loop of chain stitches or a small piece of ribbon.
Stitch marker: To mark the beginning of each round, since this pattern is worked in a continuous spiral.
Yarn needle: For weaving in ends and sewing pieces together.
Scissors: For cutting yarn.
Pattern Notes
This pattern is written in American crochet terminology. Here is a quick reference for the stitches and abbreviations used throughout.
MR – Magic ring (also called magic circle)
ch – Chain stitch
sl st – Slip stitch
sc – Single crochet
inc – Increase (two single crochets in the same stitch)
dec – Invisible decrease (insert hook through the front loops only of two consecutive stitches and complete as a single crochet)
BLO – Back loops only
FLO – Front loops only
st – Stitch
rnd – Round
The bottle is worked in a continuous spiral, meaning you do not join at the end of each round or chain one to start the next. Place your stitch marker in the first stitch of each new round and move it up as you go so you always know where each round begins.
Pattern: Baby Bottle Body
Starting at the bottom of the bottle:
Round 1: Start with white or cream yarn. 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: Work in BLO: sc in each st around. (24 sts) — This creates a subtle ridge that defines the flat base of the bottle.
Rounds 6–7: Sc in each st around. (24 sts)
Now change to your label color (blue, pink, yellow, or any color you like).
Rounds 8–12: Sc in each st around. (24 sts) — This section represents the label of the bottle. You can do a simple color change for a single color label, or stripe it with two colors if you prefer.
Change back to your white or cream yarn.
Rounds 13–15: Sc in each st around. (24 sts)
Round 16: [Sc 2, dec] repeat around. (18 sts) — This begins the neck of the bottle.
Round 17: [Sc 1, dec] repeat around. (12 sts)
Round 18: Sc in each st around. (12 sts) — This is the neck section.
Round 19: Sc in each st around. (12 sts)
Round 20: Work in FLO: sc in each st around. (12 sts) — This ridge will help the nipple sit neatly on top.
Before closing, stuff the bottle body lightly with fiberfill. You want it to feel firm and hold its shape without the stuffing bulging through the stitches. If you are adding safety eyes and want a character face, attach them now on the label section between rounds 9 and 10, with about 6 stitches of space between them.
Round 21: [Sc 1, dec] repeat around. (8 sts)
Leave a long tail and close the top using your yarn needle to run the tail through the front loops of the remaining 8 stitches and pull tight to close, just like closing the top of a beanie hat. Weave in the tail securely.
Pattern: Bottle Nipple / Top Cap
The nipple is worked separately and sewn onto the top of the bottle body.
Use your light beige or skin-tone yarn and a 2.5 mm hook.
Round 1: MR, 6 sc into the ring. (6 sts)
Round 2: [Sc 1, inc] repeat around. (9 sts)
Round 3: [Sc 2, inc] repeat around. (12 sts)
Round 4: Sc in each st around. (12 sts)
Round 5: [Sc 2, dec] repeat around. (9 sts) — Begin shaping the nipple tip.
Round 6: [Sc 1, dec] repeat around. (6 sts)
Round 7: Dec 3 times. (3 sts)
Leave a long tail, close the tip of the nipple in the same way as the bottle top by running the yarn through the remaining stitches and pulling tight. Do not stuff the nipple — it looks best when it is slightly flat and the tip tapers naturally from the yarn tension alone.
Leave the base of the nipple open. You will sew this directly onto the top of the bottle body, lining it up with the ridge created in round 20 of the bottle. Use your yarn needle and a length of the cream or white yarn to whipstitch around the base of the nipple, attaching it securely to the bottle top. Take your time with this step, as a neatly sewn seam makes a big difference to the finished look.
Adding the Measurement Details
One of the details that makes this baby bottle look so realistic is the row of measurement markings on the side. You can add these with a simple running stitch using a strand of embroidery floss in a contrasting color like blue, red, or gray.
Thread your needle with a single strand of floss and bring it up from inside the bottle at the level of round 7 or 8. Create three or four small horizontal stitches spaced evenly apart, each about two stitches wide, going up the side of the bottle in the white section. These represent the milliliter markings on a real baby bottle and add an adorable realistic touch to the finished piece.
If you prefer not to embroider, you can also use a fabric paint pen in a fine tip to draw the lines on after the project is complete and dry.
Attaching the Keychain Hardware
This is the step that transforms your adorable little crocheted bottle into a functional keychain. There are a few different ways to do this depending on what hardware you have available.
The simplest method is to use your crochet hook and a length of yarn in white or a neutral color to create a short chain of about 6 to 8 stitches at the top of the nipple, then loop it back on itself and sew the ends down securely so you have a small loop. Thread your keychain ring or lobster claw clip through this loop and close it.
Alternatively, you can cut a short length of narrow ribbon, fold it in half, and sew both ends to the top of the nipple before attaching the keychain ring. This gives a slightly different aesthetic and works especially well if you are making the bottle as a gift tag, since the ribbon can double as a decorative element.
A third option, popular with crafters who make these as party favors, is to skip the keychain hardware entirely and instead create a longer chain of stitches that becomes a loop for hanging. This works beautifully for decorating gift bags or hanging the bottle from a mobile or garland.
Customization Ideas
One of the best things about a small pattern like this is how much room there is to make it your own. Here are some ideas to get your creativity flowing.
Color themes: Use pink and white for a girl-themed bottle, blue and white for a boy-themed one, yellow or mint for a gender-neutral version, or go completely whimsical with purple, rainbow stripes, or even a deep navy with gold accents for a more dramatic look.
Character faces: Adding safety eyes and a small embroidered smile turns your bottle into an adorable amigurumi character. You can also add tiny eyebrows with a single stitch of dark floss for extra expression.
Mini accessories: Pair your bottle keychain with other tiny amigurumi baby items like a mini pacifier, a small baby shoe, or a tiny onesie to create a charm bundle. These make incredible handmade baby shower gifts when several charms are grouped together on a single ring.
Holiday versions: Use red and white for a Christmas version and add a tiny green bow. Use orange and black for a Halloween bottle with a little jack-o-lantern face. Pastel yellow and lavender are perfect for Easter.
Personalization: Using embroidery floss, you can stitch a small initial or number onto the label section of the bottle to personalize it as a gift. A little “1” for a first birthday gift, for example, is a small but thoughtful detail.
Tips for a Polished Finish
Even on a tiny project, a few finishing techniques make a visible difference in the final quality.
Use a smaller hook than you might normally reach for with the yarn weight you are using. Tight stitches on amigurumi projects prevent the stuffing from showing through and create a more defined, professional-looking shape.
Always use the invisible decrease rather than a standard crochet two-together decrease. The invisible decrease pulls from the front loops only, leaving no visible bump on the outside of your work, which keeps the surface of the bottle smooth and clean.
Block your pieces gently before sewing them together if the yarn is natural fiber. Even a very light misting with water and shaping by hand while damp can make the finished piece look much more polished.
When weaving in ends, run your needle in at least two different directions through the fabric rather than just one, and pull gently so the end does not show on the outside. Clip close to the work.
Frequently Asked Questions
How long does this project take? Most crocheters complete the entire bottle keychain, including assembly and finishing, in about one to two hours. It is a wonderful project to make while watching television or as a portable take-along project.
Can I use a different yarn weight? Yes, absolutely. If you use fingering weight yarn with a 1.5 mm or 2.0 mm hook, the bottle will come out smaller and more delicate-looking. Bulky yarn will create a larger, chunkier version. Just keep in mind that the hook size should be smaller than what is recommended on the yarn label so your fabric stays tight.
Is this pattern safe for children? If you use safety eyes and secure them properly before closing the bottle, the keychain is fairly stable. However, small crocheted items with any kind of hardware attachment or small embellishments are not recommended as toys for babies or very young children. They are intended as decorative items for adults or older children.
How do I make this pattern amigurumi-safe for gifting? If you are giving the bottle to someone who will be around young children, skip the safety eyes entirely and use embroidery floss to stitch the face details instead. Make sure all yarn ends are woven in extremely securely and that the keychain hardware is attached tightly so it cannot pull free.
Final Thoughts
The crochet baby bottle keychain is one of those projects that earns a permanent spot in your go-to pattern collection. It is fast, adorable, endlessly customizable, and genuinely useful as a gift.
