How to Attach a Keychain to Your Amigurumi: A Complete Guide
If you’ve ever finished a tiny crocheted octopus or a miniature bear and thought, “This would be absolutely perfect dangling from my bag,” you’re not alone. Turning your amigurumi into a keychain is one of the most satisfying ways to show off your work, make personalized gifts, and give your creations a practical second life. But getting the attachment right — so your little character hangs securely without the yarn unraveling or the piece looking messy — takes a bit of know-how.
This guide will walk you through everything: the supplies you need, the different methods for attaching a keychain ring to your amigurumi, tips for reinforcing the connection, and advice on finishing touches that make your piece look professionally made. Whether you’re a beginner who just finished your very first plushie or an experienced crafter looking to refine your technique, there’s something here for you.
Why Turn Your Amigurumi into a Keychain?
Before we get into the how, let’s talk about the why — because it genuinely shapes how you’ll approach the project.
Amigurumi keychains are one of the most popular items at craft fairs for a reason. They’re small, charming, and incredibly personal. A keychain takes up almost no space, costs little to make beyond your time, and can be customized endlessly. Want a tiny cactus for your plant-loving friend? A miniature Shiba Inu to match someone’s dog? A strawberry for a teacher? You can crochet it, attach a ring, and hand it over as a gift that will genuinely get used every single day.
Beyond gift-giving, making your amigurumi into keychains is practical for you as a maker too. Small pieces can pile up quickly, and turning them into accessories gives each one a purpose. It also means your work travels with you — attached to a backpack, a car key, a tote bag handle — where other people can see it and ask where you got it.
There’s also a technical upside. Because amigurumi keychains are small and require careful finishing, making them teaches you to be precise and tidy. It encourages you to close your final rounds cleanly, weave in ends thoroughly, and think about structure from the very beginning of a project.
What You’ll Need
Gathering your supplies before you start saves a lot of frustration. Here’s what you’ll want to have on hand.
For the amigurumi itself, you’ll need your usual crocheting tools: yarn (cotton or acrylic work well for small pieces), a crochet hook in the appropriate size for your yarn weight, a tapestry needle for weaving in ends, scissors, stitch markers, and polyfill stuffing. If you haven’t made your piece yet, make sure you’re following a pattern sized for keychains — anything much larger than roughly two to three inches will feel bulky and heavy on a keychain.
For the actual attachment, you have a few hardware options. The most common is a split ring, which is exactly what it sounds like: a small metal ring with a double coil, similar to what holds most people’s keys. These come in a range of sizes (you’ll typically want something between 20mm and 25mm for amigurumi) and finishes — silver, gold, antique bronze, and rose gold are all easy to find at craft stores or online. You can also use a lobster claw clasp attached to a jump ring, which makes the keychain easier to clip and unclip from a bag. Another popular option is a swivel clip, which has the advantage of letting the amigurumi spin freely without the yarn twisting.
Beyond the ring itself, you may also want a short length of chain or a piece of ribbon if you’d like some distance between the ring and your amigurumi. A chain extender gives the figure room to dangle and swing rather than sitting rigidly against the key ring. Some crafters also use a small barrel-style clasp or a cord end cap, depending on the look they’re going for.
Finally, keep a strong craft glue or a small amount of fabric glue handy. This won’t replace proper sewing, but it adds an extra layer of security in some attachment methods.
Preparing Your Amigurumi Before Attaching the Ring
The attachment process actually begins before you even pick up your key ring. A few decisions made during the construction of your amigurumi will make the final attachment much stronger and more polished.
Stuff firmly near the top. If you’re planning to attach the ring at the top of your figure — which is the most common and natural-looking position — make sure the top portion is packed firmly with polyfill. A densely stuffed piece holds stitches under tension better than one that’s loosely filled. When you pull the keychain taut, you don’t want the top of your amigurumi to collapse inward.
Close your final round tightly. When you finish your last round and begin closing the piece, pull the yarn tail through the remaining stitches as snugly as you can before cinching it shut. A tight, clean closure creates a strong anchor point for your attachment. A loose or floppy closure is much more likely to pull apart over time with the stress of daily keychain use.
Leave a long tail when you finish. When you cut your yarn after closing the final round, leave a tail of at least six to eight inches rather than trimming it close. You’ll use this tail in several of the attachment methods below, and having enough length to work with makes everything easier.
Weave in all other ends thoroughly. Any loose ends that aren’t part of your attachment should be woven in and secured before you add the keychain hardware. Weave each end in multiple directions through the stuffed body of the piece so it won’t slip out. For extra security, you can add a tiny drop of fabric glue to a particularly stubborn end before trimming.
Method One: Attaching Directly with a Yarn Loop
This is the simplest method and works beautifully for pieces where the top of the head or body is the attachment point. It uses no extra hardware beyond the split ring.
Thread your tapestry needle with the long yarn tail you left when closing the piece. Bring the needle down through the center top of the amigurumi and back up through a nearby stitch, pulling it snug but not so tight that it puckers the surface. Repeat this two or three times to anchor the tail, then bring your needle up through the very center top so the yarn is emerging at the highest point of your figure.
Now, thread the yarn through your split ring and bring the needle back down through the same spot (or as close to it as possible), creating a small loop that holds the ring. Pull it snug. Come back up through the same channel and thread through the ring again. You’re essentially whipstitching the ring to the top of the piece using your yarn tail. Repeat this four to six times until the ring feels firmly anchored, then weave the remaining tail down into the body of the amigurumi and trim.
The advantage of this method is that it looks organic and seamless — the yarn connects directly to the ring with no visible hardware. The limitation is that yarn alone may wear down over time, especially if the amigurumi is used heavily. For a piece that will see everyday use, consider reinforcing this method with one of the options below.
Method Two: Using a Jump Ring and Chain
This method adds a short chain between the amigurumi and the split ring, which gives your figure more freedom of movement and reduces stress on any single attachment point.
Start by cutting a piece of fine chain to your desired length — anywhere from one to three inches is typical. Use a pair of needle-nose pliers to open a jump ring (a single, unclosed metal ring), thread one end of the chain onto it, then thread the jump ring through the loop of yarn you’ve stitched at the top of your amigurumi using Method One above. Close the jump ring firmly with your pliers so there’s no gap. Then attach your split key ring to the other end of the chain.
The chain distributes the stress of movement across multiple links rather than concentrating it at one point, which makes this a more durable long-term solution. It also adds a lovely visual effect, making the figure look like a professionally finished accessory rather than a homemade craft item. The slight jingle of chain links is also, it must be said, very satisfying.
If you’re making keychains as gifts or for sale, the chain method is worth the small extra effort and expense. A bag of jump rings and a roll of craft chain costs very little and elevates the finished product significantly.
Method Three: The Yarn Tail Loop-Through Method
If you prefer not to use any additional hardware between the amigurumi and the ring, there’s a cleaner way to create a direct connection than simple whipstitching.
After closing your final round and leaving a long tail, thread the tail onto your tapestry needle. Insert the needle down through the top of the amigurumi and out through a side stitch, essentially running the yarn through the body. Pull the tail out. Now thread the tail through your split ring and take the needle back into the same side stitch, running it through the body in the opposite direction so it emerges somewhere near the center of the piece.
The ring is now looped by the yarn tail, which passes through the body of the amigurumi like a tension rod. Tie the tail to any interior strand and weave the remainder through the stuffing and out through a bottom stitch, trim close. This internal anchoring method creates incredible hold because the ring is secured by the yarn tension through the entire body, not just at the surface.
This is especially useful for amigurumi that don’t have a clearly defined “top” — a flat figure, a character lying on its side, or any piece where you want the ring to emerge from an unexpected location.
Method Four: Adding a Cord or Ribbon Loop
Some makers prefer a fabric or cord loop over a yarn loop, both for durability and for a different aesthetic. A waxed cord, satin ribbon, or faux leather cord creates a loop that slides easily through a split ring and won’t fray or stretch the way yarn sometimes can.
Cut a piece of cord or ribbon about three to four inches long. Fold it in half to create a loop. Thread the looped end through your split ring. Then, using your tapestry needle threaded with matching yarn, stitch the two raw ends of the cord to the top of your amigurumi — passing through both the cord and the surrounding stitches multiple times to create a tight bond. You can add a drop of craft glue over the stitching for extra hold.
This method is particularly popular for chunky amigurumi or pieces made with thick yarn, where the textural contrast between the crocheted body and the smooth cord creates a nice visual balance. It’s also a good choice if you’re making the attachment hardware removable or interchangeable — you can attach a lobster claw clasp to the cord loop, allowing the amigurumi to be clipped onto different rings as needed.
Tips for Making Your Amigurumi Keychain Last
Regardless of which method you use, a few general practices will keep your keychain looking good for as long as possible.
Use yarn that suits the application. Acrylic yarn is more resistant to wear than many natural fibers, which makes it a practical choice for keychains that will be handled frequently. Cotton is a good middle ground — it’s sturdy and holds its shape well, though it can absorb oils from skin over time and may need occasional gentle cleaning.
Choose the right stuffing density. A keychain amigurumi should be stuffed a little firmer than a regular plushie, because the stuffing helps maintain the shape under the stress of hanging and swinging. Under-stuffed pieces tend to collapse and wrinkle over time.
Use a smaller hook than your yarn calls for. Many amigurumi patterns already recommend going down one hook size to create a tight fabric, but for keychains it’s worth being even more deliberate about this. Tight stitches are denser and less likely to stretch, which means the shape holds better and the stuffing is less likely to peek through.
Finish every single end with care. The ends that come from color changes, ear attachments, eye embroidery, and other details all need to be as thoroughly secured as the main closing tail. A keychain gets bumped and jostled constantly, and any loose end will eventually work its way free.
Consider a protective coating. Some crafters lightly spray their finished keychains with a fabric protector, which repels water and helps the yarn resist grime. This is entirely optional, but it’s a nice touch for pieces that will be carried daily.
Choosing the Right Amigurumi Design for a Keychain
Not every amigurumi pattern translates well to keychain size. Designs with a lot of small separate pieces — multiple tiny limbs, elaborate accessories, lots of embroidered details — can become fragile when scaled very small. For your first keychain, look for compact designs: round or oval-bodied characters, simple animals, food-themed pieces like donuts or fruit, or geometric shapes.
The best keychain amigurumi tend to be ones where most of the personality comes from the face rather than the body shape. A pair of safety eyes, a tiny embroidered smile, maybe a slight blush mark — these details read beautifully at small scales and make the character feel expressive and finished without requiring lots of structural complexity.
If you’re adapting a regular amigurumi pattern to keychain size, a general rule is to use fingering or sock weight yarn with a 1.5mm to 2mm hook, or sport weight yarn with a 2mm to 2.5mm hook. These combinations tend to produce pieces in the one-to-three-inch range, which is ideal.
Making Multiple Keychains for Gifting or Selling
Once you’ve mastered one keychain, it’s very easy to get into a rhythm and make them in batches. Set up an assembly line: crochet several bodies at once, then stuff and close them all, then attach the hardware in a single session. Buying jump rings, chains, and split rings in bulk reduces the cost per piece significantly.
If you’re selling your keychains at craft fairs or through an online shop, consistent hardware and clean finishing will set your work apart. A small backing card or a simple piece of ribbon tied around the chain adds a professional presentation without much extra cost or effort.
Final Thoughts
Attaching a keychain to your amigurumi is a small skill with a big payoff. Once you’ve got the technique down, you’ll see keychain potential in every miniature creation you make. The methods here range from the simplest yarn loop to the more polished chain-and-jump-ring approach, and none of them require expensive tools or specialized experience.
Start with one small, simple design, take your time with the finishing, and choose hardware that suits the weight and style of your piece. The result will be something that carries your handmade work out into the world, every single day, attached to something your recipient uses constantly. For a crafter, there’s really no better kind of gift.
Happy hooking — and happy attaching.
