Most amigurumi involves sewing limbs onto a body, and I know that's the point where a lot of projects get abandoned in a basket.
Threading a tapestry needle, aligning parts, fighting with stuffing that keeps poking out. It's genuinely tedious.
This jellyfish solves that completely.
Everything is worked in one continuous spiral. The head grows from a magic ring, the tentacles chain off the bottom edge, and you close the whole thing without a single seam.
It's small enough to finish in under an hour and makes a ridiculously cute keychain, bag charm, or last-minute gift topper.
The spiral construction also means there's no visible join line on the back of the head. Just smooth, even stitches all the way around.
Why You'll Love This Crochet Jellyfish
The no-sew aspect is the headline feature.
When I teach amigurumi to beginners, the sewing stage is where faces fall. People who crocheted the body confidently suddenly look lost threading a needle.
This pattern eliminates that moment entirely. You finish the final round, cinch it closed, and your jellyfish is done.
Tentacles use simple chains with single crochets worked back along them. No separate pieces. No attaching. They flow directly from the bottom edge of the head in a logical, intuitive sequence.
The scale is satisfyingly small.
At about 4 inches tall including tentacles, one jellyfish uses roughly 15 grams of yarn. If you have a stash of partial skeins from other projects, this is the perfect scrap-eating pattern.
I made five in different colors for my niece's backpack and still had yarn left over.
For crocheters who've only worked flat, this introduces spiral rounds gently.
There's no joining, no slip stitching at the end of each round. You just keep going around and around, marking your spot with a stitch marker or a scrap of contrasting yarn.
That continuous spiral technique appears in beanies, baskets, and larger amigurumi. Learning it on a tiny jellyfish builds confidence without stakes.
Materials Needed
- Small amounts of lightweight (#3) yarn in two colors: head color (about 12 grams) and tentacle color (about 8 grams)
- 3.5 mm (E-4) crochet hook
- Stitch marker or scrap of contrasting yarn
- Scissors
- Small amount of polyfill stuffing
- Tapestry needle for weaving ends only
- Keychain clasp with small lobster clip (optional)
The yarn can be any smooth, plied fiber with good stitch definition. Cotton and cotton blends keep stitches crisp and visible, which helps when you're counting increases in a spiral.
Lion Brand 24/7 Cotton (about $4.99 per 186-yard ball) is my go-to for amigurumi. The mercerized finish has a subtle sheen that looks polished at this small scale.
One ball in each color will make multiple jellyfish, or a whole ocean-themed set if you also use the octopus variation.
The hook should be slightly smaller than your yarn label recommends. Tight stitches prevent stuffing from showing through the fabric, which matters especially on the rounded head.
Best Yarn Choices for Tiny Amigurumi
Cotton gives you defined stitches that are easy to count.
When you're increasing and decreasing in a spiral, being able to see exactly where your hook goes matters more than drape or softness.
Paintbox Yarns Cotton DK ($3.99 per 137-yard ball) comes in over 60 colors and the palette range means you can make jellyfish in realistic ocean tones or bright, playful neons.
Acrylic works if it's smooth rather than fuzzy. Hobby Lobby's I Love This Yarn Sport Weight has a silky feel and doesn't pill with handling, which matters for something that'll dangle from a bag.
Avoid textured yarns like bouclé or chenille for your first attempt. Those fibers obscure stitch definition and make counting rounds genuinely difficult.
For the tentacles, use the same fiber as the head or switch to a slightly thinner yarn for tighter curls.
A sport weight tentacle yarn paired with a DK head yarn creates tentacles that spiral more tightly and hold their shape better.
Gauge, Size Guide & Must-Have Tools
Gauge isn't critical for amigurumi the way it is for garments. But it's still helpful to know what you're aiming for.
With a 3.5 mm hook and DK cotton, expect about 6 single crochets per inch and 7 rows per inch worked in continuous spirals.
Tighter is better than looser. If you can see polyfill through your stitches, drop down a hook size.
Finished dimensions:
- Head width: about 2.4 inches across
- Total height including tentacles: about 4 inches
- Tentacle length: about 2.5 inches each
For a larger jellyfish, bump to worsted weight yarn and a 4.0 mm hook. The pattern scales up proportionally. For a mini version, use fingering weight and a 2.5 mm hook.
Must-have tools:
- 3.5 mm hook: A sharp-ish tip helps when working into tight stitches. Clover Amour or Tulip Etimo both have excellent points for this.
- Stitch marker: Absolutely non-negotiable for spiral work. Without a marker, you cannot tell where your round begins and ends. Locking markers stay put better than split-ring styles.
- Small sharp scissors: You'll snip close to the fabric multiple times. Embroidery scissors are perfect.
Pattern Notes & Tips Before You Start
Spiral crochet means no joining at the end of each round.
Instead of slip stitching to close a round and chaining up, you work the first stitch of the new round directly into the first stitch of the previous round. The rounds flow into each other seamlessly.
Your stitch marker goes into that first stitch of each round. Move it up every time you complete a full circle. Without it, you'll lose track within three rounds.
Stuff as you go rather than waiting until the opening is small.
On round 6 or 7, when the opening is still wide enough to fit two fingers, push small tufts of polyfill into the head. Don't overstuff. The head should feel firm but still squishable, like a ripe berry.
The tentacles are worked directly into the bottom edge of the head. Each tentacle is a chain with single crochets worked back along it, then anchored to the head with a slip stitch before the next tentacle begins.
Read through the tentacle section before you start. The rhythm is simple once you've done one, but the first one can feel confusing in writing alone.
Abbreviations Explained
- ch – chain: Yarn over, pull through loop.
- sc – single crochet: Insert hook, yarn over, pull up loop, yarn over, pull through both loops. Your main stitch for all of amigurumi.
- inc – increase: Work two single crochets into the same stitch.
- dec – decrease: Insert hook into front loop of next stitch, insert hook into front loop of following stitch, yarn over, pull through both front loops, yarn over, pull through both loops on hook. This is the invisible decrease, and it's worth learning because it hides the decrease line.
- sl st – slip stitch: Insert hook, yarn over, pull through stitch and loop.
- rep – repeat: Work the instruction set again the number of times specified.
- st – stitch: The V at the top of a completed stitch.
Step-by-Step No-Sew Spiral Jellyfish
Starting the Head
Foundation: Make a magic ring. Chain 1 to secure.
If magic rings frustrate you, chain 2 and work round 1 into the second chain from the hook. The hole in the center will be slightly larger but closes with the tail thread.
Round 1: Work 8 sc into the ring. Place your stitch marker in the first sc of this round. Pull the ring tail gently to close the center, but don't tighten fully yet if you plan to attach a keychain clasp from the inside. (8 stitches)
Round 2: Inc in each stitch around. Move your marker up to the first stitch of this new round. (16 stitches)
Round 3: (Sc in next stitch, inc in next stitch) repeat around. (24 stitches)
Rounds 4–7: Sc in each stitch around. (24 stitches per round)
These are the body rounds that build the dome of the head. Your fabric should start curving into a bowl shape. If it lies flat, your increases in round 2 or 3 may be off. Count and verify.
Round 8: (Sc in next stitch, dec over next 2 stitches) repeat around. (16 stitches)
Begin stuffing lightly at this point. Push small amounts of polyfill into the head while the opening is still wide.
Forming the Bottom Edge
Round 9: Work a round of sc into the front loop only of each stitch around. This creates a horizontal ridge that separates the head from the tentacles and gives you a clear edge to chain from. (16 stitches)
Round 10: Work sc in each stitch around through both loops as normal. (16 stitches)
Stuff more firmly now. The head should feel plump and rounded, with stuffing distributed evenly into the dome.
Crocheting the Tentacles
Tentacles are worked directly into the stitches of round 10. You'll chain from one stitch, work back along the chain, anchor to the next stitch, and repeat.
Tentacle 1: Chain 15. Starting in the 2nd chain from hook, sc in each chain back toward the head (14 sc). Sl st into the next stitch of round 10.
Tentacles 2–8: Repeat the process: chain 15, sc back along the chain, slip stitch to the next stitch of round 10.
For tighter curls, chain 12 instead of 15 and work 2 sc into each chain on the return. This forces the tentacles to spiral like corkscrews.
For straighter, more relaxed tentacles, chain 18 and work sc loosely.
Closing the Head
Round 11: After the final tentacle is anchored, sc in each remaining stitch of round 10. (16 stitches, but some already have tentacles attached to them)
Round 12: Dec around. (8 stitches)
Add final tufts of stuffing through the small opening.
Round 13: Dec around. (4 stitches)
Fasten off. Leave a 6-inch tail.
Thread the tail onto a tapestry needle. Weave the needle through the front loop only of each remaining stitch. Pull firmly to cinch the hole closed. Tie a small knot, then bury the tail inside the head by pushing the needle through the center and out the other side, pulling gently, and snipping close to the fabric.
Attaching the Keychain Clasp (Optional)
Thread a 7-inch strand of yarn through the clasp ring. Use a crochet hook to pull both ends of the strand through the top center of the jellyfish head (from the magic ring area). Tie a double knot inside the head and trim the ends.
Easy Variations & Custom Ideas
Octopus version: Same pattern but work only 4 tentacles total. Chain 20 instead of 15 for longer, more dramatic legs. The head remains identical.
Color-blocked head: Change yarn color at round 6 for a two-tone head. The jog between colors in a spiral is minimal and barely visible at this small scale.
Safety eyes: Insert 6 mm safety eyes between rounds 4 and 5, spaced about 3 stitches apart, before the head gets too small to reach inside.
Mini mobile: Make 5–7 jellyfish in graduated sizes using different yarn weights. String them on clear fishing line and hang from an embroidery hoop for a nursery mobile.
Common Troubleshooting and Fixes
Stuffing is showing through the stitches: Your tension is too loose or your hook is too large. Next time, size down half a millimeter. For the current one, you can gently push the stuffing deeper with a crochet hook and massage the fabric to spread it.
Tentacles look different lengths: Chains tighten at different rates depending on your tension. Count each chain and each return sc carefully. It's easy to miss the last chain on the return pass.
The head isn't round: Uneven increases create lumps. In round 3, make sure each increase pair lands exactly evenly. Use your stitch marker to track where each group of (sc, inc) begins and ends.
Magic ring won't close fully: Soak the center in warm water for a minute, then pull the tail firmly while the fibers are damp. Cotton especially responds to wet-blocking at this scale.
Final Thoughts
This little jellyfish has become my go-to for using up the last yards of a favorite yarn.
It takes about 45 minutes, uses negligible materials, and produces something that makes people smile when they unzip their bag and find it dangling there.
If you make a whole fleet in different colors, they look incredible clustered together on a key rack or hanging from a rearview mirror.
