Playful Crochet Monkey Keychain Pattern Kids Will Love — Mint Design

If you have been searching for the perfect small crochet project that combines cuteness, practicality, and just the right amount of challenge, you have found it. This crochet monkey keychain pattern in mint is everything you want in a handmade accessory — it is compact enough to finish in an afternoon, charming enough to give as a gift, and fun enough to make again and again in every color of the rainbow. Kids absolutely adore these little guys dangling from their backpacks, and adults secretly love them just as much.

The mint colorway gives this classic monkey design a fresh, modern twist. Instead of the traditional brown tones you might expect, the soft mint green transforms this tiny primate into something that feels almost magical — like a monkey from a storybook forest where everything grows in pastel shades. Whether you are making this for your own child, as a party favor, a stocking stuffer, or just because you needed an excuse to buy that beautiful skein of mint yarn sitting in your cart, this pattern is going to become one of your go-to makes.

Let us dive into everything you need to know to crochet your own adorable mint monkey keychain from start to finish.

Why Crochet Keychains Are the Perfect Project

Before we get into the pattern itself, let us talk about why crochet keychains deserve a permanent spot in your project rotation. For beginners, they offer a low-stakes way to practice foundational techniques like the magic ring, single crochet, slip stitch, and basic shaping — all within a project that takes a couple of hours rather than a couple of months. You get the satisfaction of a finished object quickly, which is incredibly motivating when you are still building your skills.

For experienced crocheters, keychains are the perfect palette cleanser between larger projects. When you are halfway through an intricate blanket and need something fresh and playful, a tiny amigurumi-style keychain hits exactly the right spot. They are also a wonderful way to use up small amounts of leftover yarn from bigger projects, which means this mint monkey might just be the ideal home for that partial skein that has been lingering in your stash.

From a gifting standpoint, handmade keychains are thoughtful and personal without requiring the kind of time investment that larger gifts demand. Kids especially treasure them because they get to carry something handmade just for them wherever they go — on their backpack zipper, their lunchbox, their house key, or even attached to a favorite stuffed animal.

Materials You Will Need

Gathering your supplies before you begin makes the whole process smoother and more enjoyable. Here is everything you will need for this mint monkey keychain:

Yarn: You will need a small amount of worsted weight yarn in mint green for the body. You will also want a tiny bit of cream or off-white for the face and belly area, and brown or dark taupe for the facial features and any detail stitches. The great news is that you only need scraps — a full skein will make many, many monkeys.

Hook: A 3.5mm or 4mm crochet hook works beautifully with worsted weight yarn for amigurumi-style projects. You want your tension to be tight enough that the stuffing does not show through, so if you tend to crochet loosely, go down a hook size.

Stuffing: A small amount of polyfill stuffing to give your monkey body and head that satisfying rounded shape.

Eyes: Two 6mm black safety eyes, or if you are making this for a very young child, you can embroider the eyes with black yarn instead for safety.

Keychain ring: One split ring or lobster clasp keychain attachment. These are inexpensive and available at craft stores or online in bulk.

Stitch markers: Helpful for marking the beginning of each round, especially since amigurumi is typically worked in continuous rounds.

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

Scissors: Your trusty pair.

Optional: A small piece of wire or pipe cleaner for the tail if you want it to be poseable, though this is entirely optional.

Understanding the Abbreviations

This pattern uses standard US crochet abbreviations. Here is a quick reference so you feel completely confident as you work:

MR — magic ring
SC — single crochet
INC — increase (two single crochets in the same stitch)
DEC — decrease (invisible decrease worked over two stitches)
SL ST — slip stitch
CH — chain
ST — stitch
BLO — back loop only
RND — round

If you are newer to amigurumi, the invisible decrease is worth practicing before you begin. It creates a much neater finish than a standard decrease and makes your finished pieces look more polished and professional.

Pattern Notes

All pieces are worked in continuous rounds unless otherwise noted. Use a stitch marker to mark the first stitch of each round so you always know where you are. The gauge is not critical for this project since we are not working to a specific size, but aim for a tight, even tension so the stuffing stays hidden inside.

This pattern is written for a finished monkey keychain that is approximately 3 to 4 inches tall, which is a lovely size for a keychain — substantial enough to feel like a real little creature, small enough to hang neatly without getting in the way.

The Pattern

Head

Start with your mint green yarn and create a magic ring.

Rnd 1: 6 SC into the magic ring. (6 sts)
Rnd 2: INC in each stitch around. (12 sts)
Rnd 3: [SC 1, INC] repeat 6 times. (18 sts)
Rnd 4: [SC 2, INC] repeat 6 times. (24 sts)
Rnd 5: [SC 3, INC] repeat 6 times. (30 sts)
Rnd 6–10: SC in each stitch around. (30 sts, 5 rounds)

At this point, insert the safety eyes between rounds 7 and 8, approximately 8 stitches apart. If you are using embroidered eyes, you will add those after finishing and stuffing.

Rnd 11: [SC 3, DEC] repeat 6 times. (24 sts)
Rnd 12: [SC 2, DEC] repeat 6 times. (18 sts)

Stuff the head firmly now before the opening becomes too small to work with comfortably.

Rnd 13: [SC 1, DEC] repeat 6 times. (12 sts)
Rnd 14: DEC 6 times. (6 sts)

Fasten off, leaving a long tail. Use your yarn needle to close the remaining hole and weave in the end securely inside the head.

Muzzle

The muzzle gives your monkey that characteristic round, expressive face that makes amigurumi monkeys so irresistible. Work this piece in cream or off-white yarn.

MR, 6 SC into the ring.
Rnd 1: INC in each stitch around. (12 sts)
Rnd 2: [SC 1, INC] repeat 6 times. (18 sts)

Sl st to join, fasten off with a long tail for sewing. Do not stuff the muzzle — it lies flat against the face.

Use your yarn needle to sew the muzzle onto the front of the head, centered between the eyes, spanning from about round 8 to round 12. Once attached, use brown or dark yarn to embroider a small nose at the top center of the muzzle and a little curved smile below it. The expression you give your monkey is entirely up to you — a gentle curve creates a serene little face, while a wider curve gives him a goofy grin that kids especially love.

Body

Return to your mint green yarn.

MR, 6 SC into the ring.
Rnd 1: INC in each stitch around. (12 sts)
Rnd 2: [SC 1, INC] repeat 6 times. (18 sts)
Rnd 3: [SC 2, INC] repeat 6 times. (24 sts)
Rnd 4–9: SC in each stitch around. (24 sts, 6 rounds)
Rnd 10: [SC 2, DEC] repeat 6 times. (18 sts)
Rnd 11: [SC 1, DEC] repeat 6 times. (12 sts)

Stuff the body firmly.

Rnd 12: DEC 6 times. (6 sts)

Fasten off and close the hole as you did for the head.

Arms (Make Two)

MR, 6 SC into the ring.
Rnd 1: INC in each stitch around. (12 sts)
Rnd 2–8: SC in each stitch around. (12 sts, 7 rounds)

Stuff lightly — or leave unstuffed if you prefer flat, floppy arms that feel more lifelike and are easier to position. Flatten the arm and SC across the opening to close it, creating a flat end for easy sewing.

Legs (Make Two)

MR, 6 SC into the ring.
Rnd 1: INC in each stitch around. (12 sts)
Rnd 2–7: SC in each stitch around. (12 sts, 6 rounds)

Close the same way as the arms, flattening and single crocheting across the opening.

Ears (Make Two)

In mint green:
MR, 6 SC into the ring.
Rnd 1: INC in each stitch around. (12 sts)
Sl st to join. Fasten off with a long sewing tail.

These small discs will be folded slightly and sewn to the sides of the head to give your monkey those characteristic round ears.

Tail

The tail is one of the most charming parts of this design and gives the keychain wonderful personality. Chain 20 in mint green, then work SC back along the chain for a rounded tail. For a curly tail effect, work 2 SC in each chain stitch as you go back — this extra fullness causes the tail to curl naturally into that classic monkey shape.

Fasten off with a long sewing tail.

Assembly

Now comes the deeply satisfying part where all your individual pieces come together into a complete little monkey. Take your time with assembly — careful sewing at this stage makes an enormous difference in the final result.

Start by attaching the head to the body. Position the head so it sits slightly forward, which gives your monkey a natural, animated look rather than a stiff, vertical posture. Sew securely through several loops on each piece, going around the join at least twice for durability.

Next, attach the ears to the sides of the head at around round 4 or 5, bending each ear disc slightly so it curves outward from the head in a natural way. Sew through the flat edge of each ear to secure.

Attach the arms at the sides of the body, just below where the head joins, angling them slightly downward and forward so your monkey looks like he is reaching out for a hug. Kids particularly love this detail.

Sew the legs to the bottom of the body, positioning them so the monkey can sit upright if placed on a flat surface. This is a nice touch even on a keychain — it means he looks perfectly at home whether he is hanging on a backpack or sitting on a shelf.

Finally, attach the tail to the back of the body near the base. If you made the curling version, you can tack the tip of the curl to the body or leave it free — a free curl has a wonderful bounciness to it that makes the keychain extra fun.

Attaching the Keychain Ring

To attach your split ring or lobster clasp, cut a short length of yarn in mint green, thread it through the top of the head (right at the crown, through the center), and then thread both ends through the keychain ring. Tie a secure knot and trim the ends neatly, or use your yarn needle to weave the ends down into the head so nothing is visible from outside.

Alternatively, you can crochet a small chain loop at the very top of the head during assembly — chain 6, join with a slip stitch to form a loop, and attach the keychain ring through this loop. This method is slightly more secure for keychains that will see heavy use.

Customization Ideas

One of the best things about this pattern is how easy it is to personalize. Once you have made your first mint monkey, you will start seeing endless possibilities.

Different colors: While mint is the star of this design, the same pattern works beautifully in lavender, coral, sky blue, sunny yellow, or even classic brown if you want a more traditional monkey look. Make a whole rainbow collection.

Add a bandana: Chain 15, work 3 rows of SC, and tie it around your monkey’s neck for an adventurous look kids absolutely love.

Tiny accessories: A miniature crochet banana is surprisingly quick to make and turns your monkey keychain into a complete little scene. Chain 6, work SC back along the chain, and curve it into a banana shape before sewing it into one of the monkey’s hands.

Personalization: Embroider a small initial on the monkey’s belly in a contrasting color. This makes the keychain feel like a truly personal, one-of-a-kind gift.

Size variation: Want a bigger monkey? Simply move up to bulky yarn and a 6mm hook. The same pattern will produce a monkey roughly twice the size, which works wonderfully as a bag charm or small plush toy.

Tips for the Best Results

If your magic ring keeps pulling loose, try starting with a slip knot and working your first round into the slip knot loop instead. Some crocheters find this easier to control, especially with slippery yarn.

To achieve the tightest, neatest seams when sewing pieces together, always use your working yarn color that matches the piece you are attaching. This makes any less-than-perfect stitches invisible from the outside.

If you find continuous rounds disorienting at first, try placing a stitch marker in a different color at the beginning of every fifth round as well as your usual start-of-round marker. Having these intermediate landmarks makes it much easier to track your progress and catch mistakes early.

For the curliest tail possible, try working your increases at a ratio of 3 SC per chain stitch on the return — this creates an exaggerated curl that is absolutely irresistible.

If you are giving this keychain to a child under three years old, skip the plastic safety eyes entirely and embroider both the eyes and nose with black yarn. Embroider the eyes as small tight circles or simple French knots, and the result is just as charming while being completely safe for little ones.

Storing and Caring for Your Monkey Keychain

Acrylic yarn keychains are wonderfully durable and can be hand washed in cool water with a small amount of gentle soap when they inevitably get the kind of love that leaves smudges and sticky fingerprints. Press out excess water with a towel and allow to air dry fully before using again. Avoid putting amigurumi pieces in the dryer, as this can distort the shape and loosen the sewn joins over time.

If you used a natural fiber like cotton for your mint monkey, the same gentle hand washing applies, but be especially careful not to wring or twist the piece, as wet cotton is more vulnerable to losing its shape.

Sharing Your Make

If you crochet your own mint monkey keychain using this pattern, sharing your finished project brings so much joy to the crochet community. Tag your photos so other makers can find your version and be inspired by the choices you made — your color combination, the expression you gave your monkey, any accessories you added. Seeing how many different monkeys can emerge from the same pattern is one of the most delightful things about sharing crochet designs.

Leave a comment with any questions, modifications you loved, or tricks you discovered along the way. Patterns like this one get richer every time a new maker brings their own creativity and perspective to them, and your insights might be exactly what someone else needs to finally feel confident enough to try their first amigurumi project.

This little mint monkey has a way of finding exactly the right home — bouncing on a child’s backpack, hanging from a set of house keys, tucked into a birthday gift bag alongside something bigger, or sitting on a desk as a cheerful reminder that not everything in life needs to be serious. Make one, make five, make a whole troop. They are waiting to go on their adventures, and you are just the person to bring them to life.

Happy crocheting.
