Free Crochet Pattern: Soot Sprite Keychain

If you’ve ever watched My Neighbor Totoro or Spirited Away, you already know the quiet magic of soot sprites. Those tiny, round, wide-eyed creatures that skitter across the screen for just a few moments manage to leave a lasting impression on just about everyone who sees them. They’re simple, they’re adorable, and honestly, they’re the perfect subject for a crochet project. This free crochet pattern will walk you through how to make your own soot sprite keychain — a little amigurumi-style charm that’s small enough to finish in an evening and cute enough to have everyone asking where you got it.

Whether you’re a seasoned crocheter looking for a quick and satisfying project or a beginner who wants to try amigurumi for the first time, this pattern is approachable, fun, and endlessly giftable. Let’s get into it.

What Is a Soot Sprite?

For anyone who needs a quick refresher, soot sprites (called “susuwatari” in Japanese, which loosely translates to “traveling soot”) are small, round, black creatures that appear in several Studio Ghibli films. They do simple, cheerful work — carrying coal, running errands — and they disappear into sparkles when they’re startled. Their design is elegantly minimal: a perfectly round black body, two big white eyes, and sometimes tiny little arms. That simplicity is exactly what makes them so fun to recreate in yarn.

A crochet soot sprite keychain captures all of that charm in miniature. Attached to a keychain ring, it becomes something you can carry around every day — clipped to a backpack, hanging from your keys, dangling from a zipper pull. It’s a little piece of Ghibli magic that fits in your pocket.

Materials You’ll Need

Before you start crocheting, gather your supplies. One of the best things about this project is that it uses very little yarn and very few tools, so it’s a great stash-buster and a low-investment project even if you need to pick up a few things.

Yarn: You’ll need a small amount of black yarn in a worsted or DK weight. A single skein will make dozens of these sprites, so if you have any dark yarn scraps lying around, this is the perfect use for them. For the eyes, you’ll need a tiny bit of white yarn or white felt, or you can use 6mm or 8mm safety eyes instead — both options look great.

Hook: A 2.5mm or 3mm crochet hook works well for this project. Going down in hook size from what the yarn recommends will create a tighter fabric so the stuffing doesn’t show through.

Stuffing: A small amount of polyester fiberfill. You really don’t need much — just enough to fill a small round shape.

Keychain hardware: One or two keychain rings, available at any craft store or online. You can also use lobster claw clasps, jump rings, or even just a simple split ring.

Tapestry needle: For weaving in ends and, if you’re using yarn for the eyes, stitching them on.

Stitch marker: Optional but helpful for keeping track of rounds.

Scissors: For cutting yarn.

If you want to add a little extra detail, you can also grab some white embroidery floss or a white paint pen for adding highlights to the eyes, and maybe a tiny bit of gray yarn for subtle texture. These are totally optional — the basic version is already incredibly cute.

Abbreviations and Stitch Guide

This pattern uses standard US crochet terms.

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 — Decrease (invisible decrease: insert hook into front loops of next two stitches, yarn over and pull through both, yarn over and pull through remaining two loops)
st(s) — Stitch(es)
BLO — Back loop only

If you’re new to amigurumi, one important note: this pattern is worked in continuous rounds, meaning you don’t join at the end of each round with a slip stitch. Instead, you just keep going. Using a stitch marker to mark the first stitch of each round will help you keep count.

Pattern Instructions

The Body

The soot sprite’s body is a simple sphere. The key to a nice round shape is working through your increases and decreases evenly and making sure your tension stays consistent.

Round 1: Make a magic ring, work 6 sc into the ring. Pull the tail to close. (6 sts)

Round 2: Inc in each stitch 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 4, inc — repeat around. (36 sts)

Rounds 7–10: Sc in each stitch around. (36 sts, 4 rounds)

Round 11: Sc 4, dec — repeat around. (30 sts)

Round 12: Sc 3, dec — repeat around. (24 sts)

At this point, if you’re using safety eyes, insert them now between rounds 7 and 8, spaced about 6 to 8 stitches apart. If you’re embroidering the eyes, you’ll do that after the body is closed.

Round 13: Sc 2, dec — repeat around. (18 sts)

Begin stuffing the body now. You want it to be firm but not stretched — the sphere should hold its round shape without the stuffing making the black fabric look strained or gappy.

Round 14: Sc 1, dec — repeat around. (12 sts)

Round 15: Dec around. (6 sts)

Finish stuffing if needed, then close the opening. To close, cut your yarn leaving a 6-inch tail, thread your tapestry needle, and run the needle through the front loops of all remaining stitches. Pull tight to close the gap, then weave in the end securely.

The Eyes (Yarn Method)

If you’re using safety eyes, skip this section — they’re already in. If you’re embroidering the eyes with white yarn or floss, here’s how to get that classic soot sprite look.

Thread a length of white yarn onto your tapestry needle. Insert the needle at the point where you want the center of one eye to be, coming up through the center of the sphere and back out at the eye position. Stitch a small circle or oval shape — soot sprite eyes are large and round, so be generous. Make several stitches close together to build up a filled circle. A diameter of about 5 to 6 millimeters looks proportionally right on a body this size.

Repeat for the second eye, keeping them level and symmetrically spaced. If you want to add a small white highlight dot to each eye (which really brings them to life), use a single straight stitch with a strand of white embroidery floss or a dot of white paint pen after the yarn eyes are in place.

Some crocheters also add a thin ring of gray or very dark charcoal yarn around the white eyes to give them a pupil-like definition. This is entirely optional, but it does give the sprite a slightly more expressive look.

Attaching the Keychain

There are a few different ways to attach your soot sprite to a keychain ring, and the method you choose can depend on how polished you want the final result to look.

The simple loop method: Cut a length of black yarn about 8 inches long. Thread both ends through the tapestry needle, fold the yarn so you have a doubled strand, and push the needle down through the top of the sprite’s head and back up a few stitches away, pulling through until you have a small loop at the top. Thread your keychain ring onto the loop, then tie the two yarn ends together in a secure knot close to the sprite’s head. Weave in the ends inside the body. This creates a clean, nearly invisible attachment.

The chain loop method: Using your hook and black yarn, crochet a short chain of about 8 to 10 stitches. Thread the chain through the top of the sprite’s head, slip both ends through the keychain ring, and sew or knot them securely. This gives you a slightly longer drop between the ring and the sprite, which some people prefer aesthetically.

Jump ring method: If you want the most secure and professional-looking attachment, use a tapestry needle to thread a piece of black yarn through the top of the sprite and thread a jump ring or a small lobster claw clasp directly onto that loop before tightening. This is especially good if the keychain will see a lot of daily use, since it distributes the weight more evenly.

Optional: Adding Tiny Arms

One optional detail that takes your soot sprite from round yarn ball to full character is adding tiny little arms. In the films, soot sprites sometimes have small, wiggly limbs, and a few simple chain stitches are all you need to suggest this.

Using black yarn, crochet a chain of 4 to 5 stitches. Slip stitch back along the chain to create a small arm shape. Make two of these. Using your tapestry needle, sew one to each side of the sprite’s body, roughly at the equator of the sphere. Keep them pointing slightly upward and outward — this gives the sprite an endearing “I’m just here!” posture. Weave in all ends carefully.

Alternatively, you can use small lengths of black pipe cleaner inserted into the sides of the body before you close the final rounds. The pipe cleaner can then be bent into position, and because it holds its shape, you can pose the little arms however you like. Just make sure to fold the sharp ends over before inserting them so they don’t poke through the fabric.

Tips for the Best Results

Go down in hook size. Amigurumi works best when your stitches are tight enough that the stuffing doesn’t peek through. If you’re working with worsted weight yarn, try a 3mm hook instead of the standard 5mm you might use for other projects. The fabric will feel stiffer, but that’s exactly what you want.

Use the invisible decrease. The standard decrease can create a small visible gap in your work, which matters more with dark yarn than it might with lighter colors. The invisible decrease — working through only the front loops of the two stitches — creates a much smoother surface.

Stuff firmly. A loosely stuffed sprite will look a little deflated and won’t hold its round shape as well. Add stuffing gradually and check the roundness as you go.

Leave a long enough tail at the start. When you make your magic ring, leave a tail of about 6 inches. After you’ve finished round 2 or 3, you can use that tail to close up any remaining gap in the center of the magic ring, which keeps the sphere looking neat.

Make a batch. Once you’ve made one soot sprite, you’ll want to make ten more. They’re fast — each one takes under an hour once you’re comfortable with the pattern — and they make wonderful gifts, bag charms, gifts for friends’ birthdays, ornaments, or party favors. Consider making a little family of different sizes by adjusting your yarn weight: use fingering weight for tiny sprites and bulky yarn for oversized ones.

Customization Ideas

One of the joys of a simple pattern like this is how much room there is for personalization.

You can give your soot sprite a different eye style — some crocheters make the eyes slightly oblong rather than circular for a sleepier expression, while others add tiny eyelashes with a few straight stitches of black embroidery floss. You can also experiment with color: while classic soot sprites are black, a soft gray version makes a lovely alternative, and a deep navy blue or purple creates a more fantastical creature.

Adding a small star, heart, or candy charm to the keychain ring alongside your sprite is a popular choice. You can also make a matching sprite in a slightly larger or smaller size and attach both to the same ring for a whimsical paired effect.

If you crochet with glow-in-the-dark yarn — which is available from several online yarn shops — your soot sprite will have an extra bit of magic when the lights go out.

A Note on Gifting This Pattern

If you make soot sprites to give as gifts, they tend to be an instant hit with anyone who loves Studio Ghibli, anime, or just charming handmade things in general. They’re appropriate for all ages (just swap safety eyes for embroidered ones if you’re gifting to very young children), easy to customize, and small enough that you can make several in one sitting.

You’re welcome to sell finished items made from this pattern — just please don’t redistribute the pattern itself as your own work. A link back here is always appreciated if you share your finished sprites online.

Finishing Thoughts

The soot sprite keychain is one of those patterns that earns a permanent spot in your project rotation. It’s quick to make, uses almost no materials, and results in something genuinely delightful. There’s something meditative about working in the round on a tiny object like this — the focus required to keep track of your stitches, the moment when the sphere starts to take shape, the satisfaction of adding those big white eyes and watching a flat ball of yarn suddenly look like a character.

If this is your first amigurumi project, welcome to a very enjoyable rabbit hole. The techniques you practice here — the magic ring, working in continuous rounds, increasing and decreasing to shape a sphere, closing and stuffing — are the foundation of almost every amigurumi pattern out there. Once you’ve made a few soot sprites, you’ll have the confidence and muscle memory to tackle more complex creatures.

And if you’re an experienced crocheter who just needed a quick, satisfying project, hopefully this delivered. Sometimes the best thing you can make is something small, sweet, and finished before bedtime.

Happy crocheting — and watch out for soot sprites in dark corners.
