How to Sew a Keychain onto an Amigurumi: A Complete Step-by-Step Guide
If you’ve ever finished a tiny crocheted animal and thought, “I wish I could carry this with me everywhere,” you’re not alone. Turning your amigurumi into a functional keychain is one of the most satisfying finishing techniques you can learn. It transforms a cute little figure into a practical accessory — a personal touch on your bag, backpack, or keys that also makes for an incredibly thoughtful handmade gift.
But sewing a keychain onto an amigurumi isn’t quite as simple as pushing a hook through the top and calling it done. Do it wrong and you risk the attachment pulling loose, the figure hanging lopsided, or the hardware cutting through your yarn over time. Do it right, and you end up with something durable, professional-looking, and sturdy enough to survive daily use.
This guide walks you through everything you need to know: the supplies you’ll need, how to choose the right attachment point, how to anchor the hardware securely, and how to finish everything off neatly so there are no loose ends — literally.
Why Adding a Keychain to Amigurumi Is Worth the Extra Effort
Before diving into technique, it’s worth understanding why a properly sewn keychain attachment matters so much more than a quick improvised solution.
Keychains take a beating. They get tossed into bags, jostled around, pulled on repeatedly, and exposed to friction from other objects. An amigurumi that sits sweetly on a shelf can be made with lighter yarn and a looser tension, but one destined for keychain life needs a reinforced connection between the figure and the hardware.
A poorly attached keychain ring can do real damage to your work. If the ring is too heavy or the attachment point is too weak, the hardware can gradually widen the stitches where it’s attached, causing the stuffing to peek through or the figure to deform over time. Worse, it can pull free entirely — and nobody wants to find half a crocheted bunny dangling from an empty keychain ring.
Taking the time to sew the attachment point properly, use the right materials, and reinforce the connection means your amigurumi keychain will last for years, not weeks.
What You’ll Need
Gathering your supplies before you start will make the whole process smoother. Here’s what to have on hand:
Your finished amigurumi. It should already be stuffed, sewn closed, and have all its limbs and features attached. The keychain attachment is always the very last step.
A keychain ring or lobster clasp. Standard split rings (the coiled metal rings you see on most key sets) work well. For a more polished look, consider a swivel keychain clip with a jump ring, which lets the amigurumi rotate freely and reduces stress on the attachment point. You can find these at craft stores or online in bulk packs for very little cost.
A jump ring (optional but recommended). A small metal jump ring threaded between your yarn loop and the keychain hardware acts as a buffer, distributing the weight more evenly and preventing direct friction between the metal ring and your yarn.
Strong yarn or embroidery floss. You’ll use this to create a yarn loop or wrap that connects your figure to the keychain hardware. Choose a fiber that matches or complements your amigurumi yarn, and make sure it’s strong — wool or acrylic are both fine, but avoid loosely spun or overly delicate fibers for this particular task.
A tapestry needle. This is your main sewing tool. You want one with a blunt tip and a large enough eye to thread your yarn through comfortably.
Scissors.
Pliers (optional). If you’re using a jump ring, you’ll need flat-nose pliers to open and close it without distorting its shape.
A piece of felt or stiff fabric (optional but helpful). Cutting a small circle or square of felt and sewing it on the inside of your attachment point adds a reinforcing layer that distributes tension across more stitches rather than concentrating it in one spot.
Choosing the Right Attachment Point on Your Amigurumi
Where you sew the keychain matters a great deal — both for aesthetics and for structural integrity. For most amigurumi figures, the top of the head is the natural and most practical attachment point. It keeps the figure hanging upright, which usually looks best, and the top of the head tends to have a concentration of stitches that can handle some tension.
However, not every figure lends itself to a top-of-head attachment. A flat amigurumi (like a coin purse style or a disc-shaped character) might look better with a side attachment. A figure with a very large head relative to its body might hang better if the attachment is positioned slightly toward the back of the top, so the face tilts forward attractively rather than hanging completely straight.
Here’s how to find the right spot:
Hold your finished amigurumi by a single stitch at the very top center of the head and let it dangle. Does it hang level and face forward? If yes, that’s your attachment point. If it tilts forward, backward, or to one side, shift the pinch point until you find the spot where it hangs in a way you’re happy with. Mark that spot with a stitch marker or a small piece of scrap yarn before you move on.
For figures with ears, horns, or other elements on top of the head, you have options. You can attach the keychain ring between the ears, directly above the center of the head, or you can run your yarn loop through the base of one of those features if it’s solidly attached. Just make sure whatever structure you’re using as an anchor is sewn securely enough to bear the weight and repeated tugging of daily keychain use.
Step-by-Step: How to Sew a Keychain onto an Amigurumi
Step 1: Prepare Your Yarn Loop
Cut a length of strong yarn or embroidery floss about 30 to 40 centimeters long. Thread it through your tapestry needle. You’re going to create a loop that passes through the top of your amigurumi and connects to your keychain hardware.
If you want an invisible attachment, use a yarn that exactly matches your amigurumi’s main color. If you want the loop to be decorative — or if you intentionally want a longer dangle between the figure and the hardware — you can use a contrasting color or a longer piece.
Step 2: Insert the Needle at Your Marked Attachment Point
Push your threaded tapestry needle down through the top of the amigurumi at your marked spot, angling it slightly so it exits through a stitch about half a centimeter away from where you entered. You’re essentially taking one stitch through the top of the figure, so that both ends of your yarn are coming out of the top of the head close together.
Pull the yarn through until you have roughly equal lengths on both sides — you should have two loose yarn tails coming out of the top of the head.
Step 3: Thread the Hardware
Before you tie anything off, thread one or both yarn tails through your keychain ring or jump ring. If you’re using a jump ring as an intermediate step, thread the yarn tails through the jump ring and then use your pliers to attach the keychain clip to the jump ring separately.
At this stage, both yarn tails should be coming out of the top of the amigurumi and looping through your hardware.
Step 4: Tie a Secure Knot
Bring both yarn tails together and tie a double or triple knot directly against the body of the amigurumi, snugged up as close to the surface of the figure as possible. This knot is what holds everything in place, so take your time and make it tight. Tug on the hardware after knotting to test the tension. It should feel firmly anchored, not wobbly.
If you feel the knot slipping or the yarn pulling through the stitches, that’s a sign you need to either use a thicker yarn, reinforce the attachment with a felt backing, or use a different knot technique.
Step 5: Weave in the Ends
Thread each yarn tail individually back through the tapestry needle and weave them into the body of the amigurumi — ideally by running them through several stitches in different directions. This is the same technique you’d use for any yarn end, but because this is a high-stress point, weave the ends a bit more thoroughly than usual. Change direction at least two or three times before trimming.
Once both ends are woven in and trimmed, give the hardware another firm tug. The connection should hold without any part of the knot being visible from the outside.
Alternative Method: Using a Crochet Loop Instead of Sewn Yarn
Some crafters prefer to work a crocheted loop directly into the top of the figure during construction rather than sewing one on afterward. If you haven’t finished your amigurumi yet, this is worth considering.
When you’re closing the top of the head, instead of immediately fastening off after your final round, work a chain of 5 to 8 stitches, then join the chain back to the top of your figure with a slip stitch to form a small loop. Fasten off and weave in the end. This loop can then be connected directly to a keychain ring or jump ring.
The advantage of this method is that the loop is integrated into the structure of the piece rather than sitting on top of it. The disadvantage is that it only works if you plan ahead — you can’t easily add it after the fact without reopening the seam at the top of the head.
Reinforcing the Attachment: The Felt Backing Method
If you’re making amigurumi keychains as gifts or to sell, the felt backing method is worth the extra five minutes it adds to your process. It significantly extends the life of the keychain attachment by distributing tension across a wider area of the figure’s surface.
Cut a small circle of felt — about the size of a large shirt button, or roughly 2 centimeters in diameter. Using a separate needle and thread (regular sewing thread works fine here), sew the felt circle to the inside of the amigurumi at the attachment point before you close it up. If you’ve already closed the figure, you can insert the felt circle through a small gap and tack it in place before fully closing.
When you then push your tapestry needle through for the yarn loop attachment, push it through the center of the felt circle as well. The felt adds a solid backing that prevents any single stitch from bearing the full load of the keychain pull.
Common Mistakes and How to Avoid Them
Using yarn that’s too thin. A single strand of fingering-weight yarn as your attachment loop is not going to hold up to daily use. Double your yarn, use a thicker weight, or switch to embroidery floss for the connection. Six-strand embroidery floss is surprisingly strong and comes in hundreds of colors.
Knotting too far from the surface. If there’s slack in the loop between your knot and the body of the amigurumi, that slack becomes the weakest point. Always tighten the knot directly against the surface of the figure.
Using a ring that’s too heavy for the figure. A bulky metal keyring on a tiny amigurumi will look awkward and will stress the attachment point unnecessarily. Match the hardware to the size of your figure. Small, lightweight lobster clasps and swivel clips are usually a better choice for miniature amigurumi than thick split rings.
Skipping the woven-in ends. It might be tempting to tie a double knot and trim the tails short, but this is how keychains come apart. Always weave those ends in properly.
Attaching the ring before testing the hang. Always do the hanging test before you finalize where you attach the hardware. A figure that hangs upside-down or at a weird angle is still technically attached to a keychain, but it’s not going to look good dangling from your bag.
Tips for Making Amigurumi Keychains to Sell or Gift
If you’re making these as gifts or for sale at craft fairs or online, a few extra touches will make your work stand out.
Use swivel-clip hardware rather than plain split rings. The swivel mechanism prevents the amigurumi from twisting around and tangling, and it gives the final product a more professional look. Swivel clips with attached chains (sometimes called keychain extension chains) also add a bit of visual interest.
Consider sizing your amigurumi deliberately for keychain use. Figures between 5 and 10 centimeters tall tend to work best — small enough to be genuinely portable, large enough to have visible detail and not be easily lost at the bottom of a bag.
Add a small tag or label if you’re selling. A simple handwritten or printed card attached to the keychain ring with the fiber content and care instructions adds a professional touch and is very easy to do.
Caring for Your Amigurumi Keychain
Once attached, amigurumi keychains should be treated gently when it comes to washing. Most amigurumi are made with acrylic or wool yarn, and neither responds well to machine washing while attached to metal hardware. If your keychain needs cleaning, detach it from the ring if possible, hand wash it gently in cool water with a tiny amount of mild detergent, reshape it by hand, and lay it flat to dry.
If the connection point starts to look stretched or the stitches around it seem to be spreading, reinforce the area by adding a few overcasting stitches around the loop with matching yarn before the damage progresses further.
Final Thoughts
Adding a keychain to an amigurumi is a small step that makes a big difference in how the finished piece looks, feels, and functions. The process is straightforward once you understand the logic behind it — you’re essentially creating a reinforced loop that can handle real-world tension without damaging the crocheted figure or pulling loose over time.
Take your time choosing the attachment point, use strong materials, tie your knots close to the surface, and weave in those ends properly. Follow those principles and you’ll end up with an amigurumi keychain that’s every bit as durable as it is adorable — something worth making and something worth keeping.
Whether you’re adding a keychain to a tiny crocheted bear, a miniature food character, or a small fantasy creature, the technique is the same. Master it once and you’ll find yourself reaching for the keychain rings every time you finish a new project.
