How to Make a Cottagecore Crochet Jellyfish Keychain: A Complete Beginner-Friendly Guide

There is something quietly magical about the cottagecore aesthetic — the lace curtains, the pressed wildflowers, the sense that every handmade object carries a little piece of its maker’s soul. And few things embody that spirit as perfectly as a tiny crocheted creature dangling from your keys, swaying gently every time you pull them from your pocket. Today, we are diving deep into one of the most charming and surprisingly achievable crochet projects for beginners and seasoned crafters alike: the cottagecore crochet jellyfish keychain.

This guide will walk you through every single step, from gathering your materials to weaving in that final end and attaching your keychain ring. Along the way, you will pick up useful tips about yarn selection, tension, and how to give your little jellyfish that distinctly dreamy, cottage-in-the-woods personality that makes this style so irresistible. Whether you have been crocheting for years or you just picked up your first hook last week, by the end of this tutorial you will have a finished jellyfish keychain you are genuinely proud of.

What Is the Cottagecore Aesthetic, and Why Does It Work So Well with Crochet?

Before we get into stitches and yarn weights, it is worth taking a moment to appreciate why this particular combination — cottagecore and crochet — feels so natural.

Cottagecore is an aesthetic rooted in romanticized rural life. It draws on imagery from old English country cottages, Scandinavian folk traditions, and a general longing for a slower, more intentional way of living. Think mushrooms, wildflowers, vintage linen, soft candle light, and anything that looks like it could have been found in a grandmother’s sewing basket. There is an emphasis on the handmade, the imperfect, and the lovingly crafted.

Crochet fits into this world beautifully because it is inherently a slow, meditative craft. Each stitch is made by hand, one loop at a time, and the resulting texture has a warmth and irregularity that no machine can replicate. A crocheted jellyfish keychain, with its soft rounded bell and trailing tentacles, looks like it swam straight out of a fairy tale tide pool. Paired with cottagecore yarn colors — dusty rose, sage green, lavender, cream, mushroom brown — it becomes the kind of accessory that makes strangers stop and ask where you got it.

Materials You Will Need

One of the great joys of this project is how little you need to get started. This is genuinely a stash-buster, meaning you can often complete an entire jellyfish using scraps of yarn you already have.

Yarn: You will want a lightweight yarn for this project — ideally a DK weight or fingering weight. Cotton yarn gives a crisp, clean look and is excellent for beginners because it does not split as easily as some other fibers. Acrylic yarn in the same weight works just as well and comes in a wider range of soft, muted cottagecore shades. For a more luxurious feel, try a cotton-linen blend or a plant-fiber yarn. You will need approximately 20 to 40 meters of your main color and a small amount of a contrasting color for the face, if you choose to add one.

Crochet Hook: A 2.5 mm to 3.5 mm hook works well depending on your yarn weight and personal tension. If you are using fingering weight yarn, lean toward 2.5 mm. For DK weight, a 3.0 or 3.5 mm hook is more comfortable.

Stuffing: A small amount of polyester fiberfill is all you need for the bell of the jellyfish. You can also use scraps of yarn rolled into a ball, which feels very cottagecore in itself.

Stitch Markers: These are helpful for keeping track of rounds when you are working in the round, as amigurumi-style crochet does not use traditional row joins.

Scissors and a Tapestry Needle: For cutting yarn and weaving in ends.

Keychain Ring and Lobster Clasp: Available at most craft stores or online, these come in gold, silver, and antique brass finishes. Antique brass or gold tends to look most at home with cottagecore styling.

Optional: Small black safety eyes (4 mm or 6 mm), embroidery floss for adding a face, or tiny seed beads for decoration.

Understanding the Stitches

This pattern uses a handful of very standard crochet stitches. If you are a complete beginner, do not be put off by the abbreviations — each one is simple once you try it a few times.

Magic Ring (MR): This is the technique used to start crocheting in the round without leaving a hole in the center. There are many video tutorials available that explain this better than any written description can. Once you learn it, you will use it in almost every amigurumi project.

Chain (ch): The most basic crochet stitch. A series of loops linked together, used here for the tentacles.

Single Crochet (sc): The fundamental building block of amigurumi. Insert hook, pull up a loop, pull yarn through both loops on hook. One stitch made.

Increase (inc): Two single crochets worked into the same stitch. This is how you make the bell of the jellyfish get wider.

Decrease (dec): An invisible decrease, where you work two stitches together to make the bell narrow again. The invisible decrease is preferred in amigurumi because it leaves fewer gaps.

Slip Stitch (sl st): Used here mainly to join and neaten edges.

If all of this is new to you, spend thirty minutes practicing just single crochets before you begin. By the time you feel comfortable with the tension, you will be ready to make your jellyfish.

The Pattern: Cottagecore Crochet Jellyfish Keychain

The Bell (worked in continuous rounds, do not join unless specified)

Round 1: Start with a magic ring. Work 6 sc into the ring and pull it closed. You now have 6 stitches.

Round 2: Inc in each stitch around. (12 stitches)

Round 3: [Sc 1, inc 1] repeat around. (18 stitches)

Round 4: [Sc 2, inc 1] repeat around. (24 stitches)

Round 5: [Sc 3, inc 1] repeat around. (30 stitches)

Rounds 6 through 9: Sc in each stitch around. (30 stitches, no change)

At this point your bell should look like a little dome — rounder and fuller at the top, with a flat opening at the bottom. This is the perfect moment to add your safety eyes if you are using them. Position them between rounds 6 and 7, spaced about 6 stitches apart. If you prefer an embroidered face, you will add that later.

Round 10: [Sc 3, dec 1] repeat around. (24 stitches)

Round 11: [Sc 2, dec 1] repeat around. (18 stitches)

Now stuff your bell with fiberfill. Do not over-stuff — you want it to feel soft and slightly squishy, not tight. A gently stuffed jellyfish has a much more charming, organic shape.

Round 12: [Sc 1, dec 1] repeat around. (12 stitches)

Round 13: Dec around. (6 stitches)

Fasten off, leaving a long tail. Thread the tail through the remaining 6 stitches and pull tight to close. Weave in the end on the inside of the bell.

Adding the Face (Optional)

If you opted for an embroidered face instead of safety eyes, now is the time. Thread a length of black embroidery floss onto your tapestry needle and pass it through the bell from the inside, emerging at the position of the first eye. Create a small French knot or a tiny satin stitch oval to form the eye, then pass back through to the inside and emerge at the position of the second eye. Repeat.

For a little smile, use a single strand of floss in the same or a slightly darker shade and embroider a gentle curve a few stitches below the eyes. Some crafters add tiny rosy cheeks using a dab of pink chalk pastel or blush powder on a cotton swab — this gives the jellyfish an absolutely endearing, slightly Victorian doll quality that feels very cottagecore.

The Tentacles

This is where your jellyfish really comes to life. Tentacles can vary enormously depending on the look you want to achieve. Long, wavy chains give a flowing, ethereal quality. Shorter, curlier tentacles look more playful and whimsical.

To attach tentacles, thread a length of yarn onto your tapestry needle and draw it through the bottom edge of the bell from the inside, leaving a long tail on the inside that you will tie off later. You can also use a slip knot directly onto the stitches at the bottom edge of the bell.

For straight tentacles: Chain 15 to 25 stitches, then slip stitch back along every other chain to create a ruffled effect. Fasten off and trim to your preferred length.

For curly tentacles: Chain 20 stitches, then work 3 single crochets into each chain stitch on the way back. This creates a natural curl that is enchanting in motion.

For beaded tentacles: Chain freely, threading small seed beads onto your yarn before you begin so they settle naturally along the chain as you work. This is a more advanced technique but produces a truly magical result.

Aim for 6 to 10 tentacles for a full, lush look. You can make them all the same length, or vary them so that some are long and trailing while others are shorter — mimicking the way real jellyfish tentacles move with the current.

Cottage core color combinations that work beautifully for tentacles: cream against dusty rose, sage green against lavender, white against mushroom, lilac against soft butter yellow.

Attaching the Keychain Ring

With your bell complete and tentacles attached, the final step is to create the loop that will connect your jellyfish to a keychain ring.

Cut a 15 cm length of yarn in your main color. Thread it through the tapestry needle and draw it through the very top of the bell at the point where you started — right at the magic ring. Pull it through so that both ends are equal length. Tie a firm double knot very close to the top of the bell, then thread both ends through the keychain ring and tie another double knot just above the ring to hold it in place. Trim the excess and add a small dot of clear craft glue to the knot if you want extra security.

Alternatively, you can use a jump ring and a lobster clasp to create a more professional-looking attachment. Open the jump ring with pliers, thread it through the top loop of the bell and through the lobster clasp, then close it again. This allows you to easily clip and unclip the jellyfish from different keychains, bags, or zipper pulls.

Tips for Getting That Perfect Cottagecore Look

Achieving the cottagecore aesthetic is as much about color and texture as it is about the crochet itself. Here are some things to keep in mind as you work.

Choose muted, earthy tones. Bright neon colors belong to a different aesthetic entirely. Look for yarns described as “dusty,” “antique,” “vintage,” “faded,” or “heathered.” Brands that cater to cottagecore palettes include Paintbox Yarns, WeCrochet, and Drops. Natural fibers like cotton, linen, and bamboo also tend to come in more muted shades by default.

Add texture where you can. A slightly fluffy or brushed yarn for the tentacles, contrasted with a smooth cotton for the bell, gives the finished piece a layered, interesting quality. Mohair yarn is divinely soft and creates a halo effect that looks particularly magical for tentacles.

Think about finishing details. A tiny dried flower glued gently to the top of the bell, a small ribbon tied around the keychain ring, or a little tag with hand-lettered text can elevate a simple crocheted jellyfish into something truly special. These small touches are at the heart of cottagecore making.

Keep your tension consistent. A too-loose tension will create gaps in the amigurumi fabric that show the stuffing inside, which detracts from the finished look. A too-tight tension makes the piece stiff and difficult to work. Aim for a fabric that feels slightly denser than you might expect — tight enough to hold stuffing without gaps, but not so tight that your hook struggles to enter each stitch.

Variations to Try Once You Have the Basic Pattern Down

Once you are comfortable with the basic jellyfish, there are so many directions you can take this pattern.

A mushroom keychain uses almost the same bell shape with a flat base and tiny embroidered spots. A strawberry keychain uses a bright red yarn with green leaves at the top. A ghost keychain — deeply cottagecore in a slightly spooky, autumn way — uses white yarn and tiny embroidered eyes and a worried little mouth. All of these use the same fundamental technique you have just learned, which means your skills are already more transferable than you might think.

You can also make the jellyfish larger by simply continuing to increase for additional rounds before you begin the straight rounds, which turns it from a keychain into a bag charm or even a small amigurumi plush to display on a shelf.

Caring for Your Crocheted Jellyfish Keychain

Because it will spend its life getting tossed into bags, pockets, and assorted handbag chaos, your jellyfish keychain will appreciate a little care now and then. Hand wash in cool water with a gentle detergent, reshape while damp, and leave to dry flat. Avoid machine washing unless you are using a yarn that is explicitly machine washable. If it gets a little squashed or lopsided from life in your bag, a gentle steam from an iron held a few centimeters away can coax it back into shape.

Final Thoughts

Making a cottagecore crochet jellyfish keychain is one of those projects that gives back far more than you put in. You spend an evening with your hook and yarn, following a simple rhythm of stitches, and you end up with something genuinely delightful — a tiny handmade creature that carries a little bit of that slow, gentle magic into your everyday life. It makes a wonderful gift, a charming market item if you sell handmade goods, or simply a sweet treat for yourself.

The best thing about this kind of project is that it asks nothing of you except your attention and your time. There is no expensive equipment required, no years of experience needed, and no single right way to do it. Your jellyfish will look slightly different from mine and slightly different from every other one ever made, and that is exactly the point. Handmade means one of a kind. In a world full of mass-produced keychains, yours will float along on its own quiet terms.

Now gather your yarn, find your hook, and let’s make something beautiful.
