Free Crochet Mushroom Pattern | Cute Kawaii Amigurumi Keychain

There is something undeniably charming about a tiny crocheted mushroom dangling from a keychain. Whether you are drawn to the whimsical aesthetic of kawaii culture, the satisfying craft of amigurumi, or simply want a handmade gift that costs almost nothing to make, this free crochet mushroom pattern is exactly what you have been looking for. In this post, I am walking you through everything you need to know to create the most adorable little fungi you have ever seen — complete with rosy cheeks, a dotted cap, and a stem that fits right in the palm of your hand.

This pattern is beginner-friendly, works up in under two hours, and uses only small amounts of yarn you probably already have in your stash. Let’s get into it.

Why You’ll Love This Kawaii Mushroom Amigurumi

If you have spent any time in the crochet community online, you know that amigurumi — the Japanese art of crocheting or knitting small stuffed animals and objects — has taken over in the best possible way. The word itself comes from the Japanese words ami (knitted or crocheted) and nuigurumi (stuffed doll), and the style is characterized by round shapes, oversized heads, and sweet expressions that give even the most ordinary objects a personality.

Mushrooms are one of the most popular amigurumi subjects, and it is not hard to see why. Their simple silhouette translates beautifully into crochet — a round cap on top of a short, chubby stem — and the kawaii design elements like blush cheeks and embroidered eyes make them look like they stepped straight out of a video game or a Japanese stationery shop.

As a keychain, this little mushroom becomes something you can carry with you every day. It also makes a wonderful gift tag, bag charm, zipper pull, or even a small ornament. Crochet multiple in different colors and you have a set of mushroom charms that would look incredible as a garland or a gift set.

Materials You Will Need

Before we dive into the pattern, here is a quick rundown of everything you need to gather. One of the best things about this project is that it requires very little — perfect for using up scraps from larger projects.

Yarn: You will need a small amount of worsted weight yarn (size 4) in two colors — one for the mushroom cap and one for the stem. Traditional mushrooms look beautiful in red and cream, but do not be afraid to go bold with pastels, neutrals, or even speckled yarn for a more realistic look. Some of my favorite color combinations include sage green with white, lilac with beige, or classic red with off-white.

Hook: A 3.5mm or 4.0mm crochet hook works well with worsted weight yarn for amigurumi. You want your stitches to be tight enough that the stuffing does not show through, so size down slightly from what the yarn label recommends.

Stuffing: A small amount of polyester fiberfill stuffing. You really only need a pinch for a project this tiny.

Safety eyes: Two 6mm black safety eyes. If you are making this for a small child, skip the safety eyes and embroider the eyes instead using black embroidery floss.

Embroidery floss: Pink or rose-colored floss for the blush cheeks, and black floss if you are embroidering the eyes rather than using safety eyes.

Tapestry needle: For weaving in ends and embroidering the facial features.

Stitch marker: To keep track of the beginning of each round. A simple piece of contrasting yarn works perfectly.

Scissors

Keychain ring or lobster clasp: A standard 25mm jump ring or a lobster clasp with a chain works great.

Abbreviations and Stitches Used

This pattern uses standard US crochet terminology. Here is a quick reference:

MR — Magic ring (also called magic circle)
ch — Chain
sl st — Slip stitch
sc — Single crochet
inc — Increase (two single crochets in the same stitch)
dec — Invisible decrease (insert hook into front loop of next two stitches, yarn over and pull through both loops, yarn over and pull through remaining two loops)
st(s) — Stitch(es)
BLO — Back loop only

All rounds are worked in continuous rounds (do not join with a slip stitch unless indicated). Use a stitch marker to track the beginning of each round.

Free Crochet Mushroom Pattern — Step by Step

The Stem

The stem is crocheted first, stuffed lightly, and then set aside while you make the cap. The cap is crocheted separately and then attached to the stem.

Round 1: Using your stem color yarn, make a magic ring. Work 6 sc into the ring. Pull the tail to close. (6 sts)

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

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

Round 4: Working in BLO only, sc in each st around. (18 sts) — This creates the little lip at the base of the cap that gives the mushroom its classic shape.

Rounds 5–7: Sc in each st around. (18 sts) — Work three more rounds in normal single crochet.

Round 8: Sc 1, dec repeat around. (12 sts)

At this point, insert your safety eyes between rounds 5 and 6, approximately 4 to 5 stitches apart. If you are embroidering the eyes, you will add them after finishing. Stuff the stem lightly with fiberfill — just enough to give it some body without making it stiff.

Round 9: Dec around. (6 sts)

Fasten off, leaving a long tail for sewing. Do not close the opening at the top yet — this is where you will attach the cap.

The Mushroom Cap

Round 1: Using your cap color yarn, make a magic ring. Work 6 sc into the ring. Pull the tail to close. (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)

Round 6: Sc in each st around. (30 sts)

Round 7: Sc in each st around. (30 sts)

Round 8: Sc 3, dec repeat around. (24 sts)

Round 9: Sc 2, dec repeat around. (18 sts)

Do not fasten off yet. At this stage, the cap should look like a little dome. If you want to add white dots to the top of the cap (the classic mushroom look), now is a great time to do it before closing up. Use white yarn and a tapestry needle to create small surface slip stitches or small french knots in a scattered pattern across the top of the dome. Alternatively, you can use small pieces of white felt cut into circles and tack them on after assembly.

Joining the Cap and Stem

Hold the stem with the open top facing up. Align the open edge of the cap over the open top of the stem. The inside bottom edge of the cap should rest right over the lip you created in round 4 of the stem — this gives the mushroom that adorable little overhang that makes it look so much like a real mushroom.

Using the long tail you left on the stem, or a new piece of yarn and your tapestry needle, whipstitch the two pieces together around the edge. Work your way around the entire circumference, pulling gently but firmly to create a neat join. Weave in any remaining ends.

Adding the Keychain Loop

Cut a 15cm length of yarn in your stem or cap color. Thread it through your tapestry needle and pull it through the top center of the mushroom cap (through the magic ring at the very tip). Tie the two ends together in a secure knot, then thread both ends through a keychain ring or jump ring before tying them off. Trim the ends neatly. Alternatively, use a small piece of chain with a lobster clasp for a more polished, jewelry-style finish.

Embroidering the Face

This is the step that brings your mushroom to life. Using black embroidery floss and a sharp needle, embroider two small dots or simple curved lines for the eyes just above the center of the stem’s front face. Curved lines stitched in a shallow “U” shape give a sweet, sleepy expression that is very on-brand for kawaii style.

For the blush cheeks, thread your needle with pink or rose embroidery floss and make three or four small straight stitches fanned out in a tiny semicircle on each side of the face. These little rosy patches are what give the mushroom its kawaii charm — simple, but completely transformative.

If you want to add a tiny smile, use two or three small straight stitches arranged in a gentle curve.

Tips for Getting the Best Results

Go slow with the magic ring. The magic ring can feel tricky at first, but it is worth mastering because it gives you a clean, tight center with no hole. If you are new to it, practice a few times with a scrap piece of yarn before starting your mushroom.

Keep your tension consistent. Amigurumi looks its best when the stitches are even and tight. If your tension is too loose, the stuffing will peek through. If it is too tight, the piece will be stiff and hard to work with. Practice will make this feel natural very quickly.

Count your stitches every round. Place a stitch marker at the beginning of every round and count before moving on. A missed increase or decrease can throw off the whole shape. It takes an extra ten seconds per round and saves a lot of frustration.

Use a smaller hook than you think you need. Amigurumi is one of the few situations in crochet where going down a hook size or even two is recommended. This keeps your stitches tight and your finished piece neat.

Do not overstuff. For a piece this small, a tiny pinch of stuffing is genuinely enough. Overstuffing a small amigurumi can distort the shape and make the seams stretch in unflattering ways.

Experiment with color. This pattern is incredibly versatile. Try a speckled or variegated yarn for the cap and a solid for the stem, or reverse the proportions and make a pale pastel mushroom with a cream-colored cap and a colored stem. Muted earthy tones like terracotta, olive, and warm tan give the mushroom a cottagecore vibe, while brights give it a more playful, toy-like feel.

Ideas for Using Your Crocheted Mushroom

Once you have made one, you will almost certainly want to make more — and the good news is that these little guys are endlessly adaptable. Here are a few ideas for what to do with them.

Gift toppers. Tie a mushroom keychain to the ribbon on a wrapped gift instead of a bow. It is more memorable than anything you could buy at a gift shop and takes almost nothing to make.

Bag charms. Clip one to your tote bag, backpack, or purse for an instant dose of personality.

Advent calendar fillers. Make twenty-four in different colors and styles to fill a handmade or DIY advent calendar. They are the perfect size and feel special in a way that store-bought trinkets rarely do.

Plant stakes. Skip the keychain hardware and instead attach a small bamboo skewer to the stem with floral wire. Push it into a potted plant for a whimsical garden marker.

Bookmarks. Attach the mushroom to a length of ribbon or a bookmark clip for a charming reading accessory.

Garlands. Make a dozen or more in graduating sizes or a rainbow of colors and string them together for a whimsical nursery decoration or party garland.

Zipper pulls. Attach one to the zipper on a jacket, bag, or pencil case.

Customizing the Pattern

The beauty of a pattern this simple is how easy it is to modify. Once you are comfortable with the basic technique, the possibilities are genuinely endless.

You can scale the pattern up or down by changing your yarn weight and hook size. Use fingering weight yarn and a 2.0mm hook for a truly tiny, delicate mushroom, or jump up to a bulky weight yarn and a 6.0mm hook for a big, squishy version that would make a lovely plushie or pincushion.

Add a tiny bow at the base of the cap using a small scrap of ribbon. Swap the embroidered face for a grumpy expression, a surprised open mouth, or winking eyes to create a whole cast of mushroom characters. Use glow-in-the-dark yarn for the spots and imagine the delight of a child discovering them in the dark.

You can also turn the mushroom into a wearable piece by attaching a brooch pin to the back of the stem. A small cluster of two or three different-sized mushrooms on a single pin looks gorgeous on a sweater lapel, a hat brim, or a canvas bag.

Gauge and Sizing

With worsted weight yarn and a 3.75mm hook, the finished mushroom measures approximately 5cm (2 inches) tall and 4cm (1.5 inches) wide at the widest point of the cap. Because this is a stuffed amigurumi rather than a flat piece, gauge is less critical than it would be for a garment — what matters more is that your fabric is tight enough to hold the stuffing inside without gaps. A good test is to hold your crocheted swatch up to a light source. If you can see through the stitches easily, your tension is too loose.

A Note on Gifting Handmade Items

If you are making this mushroom keychain as a gift, especially for a child, please use embroidered eyes rather than safety eyes and ensure all embellishments are very securely attached. Safety eyes, while named for their locking mechanism, are still a choking hazard for children under three. When in doubt, embroider everything.

For older children and adults, the safety eyes are perfectly fine and give a cleaner, more polished look than embroidery in most cases.

There you have it — everything you need to crochet the most charming little kawaii mushroom keychain imaginable. I hope this pattern brings you as much joy to make as it does to carry around or give away. There is something genuinely lovely about a handmade object, no matter how small, and this tiny mushroom carries a lot of heart for something that fits in the palm of your hand.
