Knit a Mini Earth for Your Keyring!

There’s something wonderfully satisfying about carrying a tiny handmade object with you everywhere you go. Whether you’re a seasoned knitter looking for a quick weekend project or a beginner wanting to try something new, this mini earth keyring is the perfect make. It’s small, it’s meaningful, it’s charming, and it only takes a few grams of yarn and an afternoon of your time. By the end of this tutorial, you’ll have a perfectly round little planet dangling from your keys, your bag, or your zip pull — and people will absolutely stop to ask you about it.

This project has become one of my favourite things to make and give. It works beautifully as a gift, a market stall piece, or a personal treat. I’ve made them in batches of ten while watching films, gifted them at Christmas tucked inside cards, and kept one on my own keys for the past two years. They wear surprisingly well, and the tiny size makes them feel like little treasures.

Let’s get into everything you need to know.

What You’ll Need

Before you cast on, gather your materials. The good news is that this project uses almost nothing in terms of yarn, so it’s a wonderful way to use up those tiny scraps lurking at the bottom of your stash.

Yarn: You’ll need a small amount of blue yarn and a small amount of green yarn. I recommend a DK or light worsted weight yarn in a deep ocean blue and a rich leafy green. The exact shades are entirely up to you — some people love a realistic blue-green combination, while others prefer something more whimsical, like teal and lime. Either way, the effect is gorgeous. You need so little yarn for this project that a single leftover ball from any previous make will more than do the job.

Needles: Use 2.5mm or 3mm double-pointed needles (DPNs). Because you’re working in the round on such a tiny scale, DPNs are the most practical choice here. If you’re comfortable with the magic loop method, you can absolutely use a short circular needle instead, but most knitters find DPNs easier at this scale.

Stuffing: A small amount of toy stuffing or polyfill is ideal. You only need a pinch — enough to make the finished ball feel firm and round.

Keyring hardware: A small split ring or keyring loop, available from most craft shops or online in packs of mixed sizes. A lobster clasp keyring with a short chain also works well if you want a little extra length between the planet and your keys.

Tapestry needle: For weaving in your ends neatly.

Stitch markers: Optional but helpful for keeping track of your increases and decreases.

Gauge and Sizing

Your finished mini earth should measure roughly 3.5 to 4 centimetres in diameter once stuffed and finished, making it comfortably small enough for a keyring without being so tiny that it becomes fiddly to knit. If you want a slightly larger version — perhaps for a bag charm rather than a keyring — simply go up a needle size or use a slightly chunkier yarn.

Gauge isn’t critical for this project since you’re not fitting it to a body. What matters most is that your knitting is tight enough that the stuffing won’t show through between the stitches. If you can see daylight through your work when you hold it up, go down a needle size.

Pattern Notes

This project is knitted in the round from the bottom up, using the classic amigurumi-style construction of increases to the widest point and then decreases back down to close the top. The green yarn is used for the continents, added as simple intarsia or duplicate stitch sections. Don’t worry if intarsia in the round sounds intimidating — I’ll explain both options clearly and you can choose whichever feels most comfortable.

The pattern uses standard knitting abbreviations: k for knit, p for purl, kfb for knit front and back (an increase), and k2tog for knit two together (a decrease). MC stands for main colour (blue) and CC stands for contrast colour (green).

The Pattern

Cast on: Using your blue yarn and DPNs, cast on 6 stitches and distribute evenly across three needles, with 2 stitches on each. Join to work in the round, being careful not to twist.

Round 1: Knit all stitches. (6 sts)

Round 2: Kfb in every stitch. (12 sts)

Round 3: Knit all stitches. (12 sts)

Round 4: (K1, kfb) repeat to end. (18 sts)

Round 5: Knit all stitches. (18 sts)

Round 6: (K2, kfb) repeat to end. (24 sts)

Round 7: Knit all stitches. (24 sts)

Round 8: (K3, kfb) repeat to end. (30 sts)

Rounds 9–14: Knit all stitches for 6 rounds. This is the widest section of your planet and where most of your green continent details will sit.

Round 15: (K3, k2tog) repeat to end. (24 sts)

Round 16: Knit all stitches. (24 sts)

Round 17: (K2, k2tog) repeat to end. (18 sts)

At this point, pause and add your stuffing. Push a small, firm pinch of polyfill inside the ball. You want it to feel solid and round but not stretched — if the stitches are pulling wide, you’ve overstuffed it.

Round 18: Knit all stitches. (18 sts)

Round 19: (K1, k2tog) repeat to end. (12 sts)

Round 20: K2tog repeat to end. (6 sts)

Cut your yarn, leaving a tail of about 15cm. Thread the tail onto your tapestry needle and draw it through all remaining live stitches. Pull up snugly to close the top of the ball, then push the needle through to the inside and weave in the end invisibly.

Adding the Continents

This is the part where your little blue ball transforms into a recognisable planet, and it’s also the part where you get to be creative.

Option one: Duplicate stitch. This is the simplest approach and the one I recommend for beginners. Once your ball is finished and stuffed, use your tapestry needle and green yarn to work duplicate stitch over selected stitches to create landmass shapes. Duplicate stitch sits on top of the existing knit stitches and mimics their shape exactly, so it blends in beautifully. You can work freehand, suggesting the rough shapes of the continents without worrying about geographic precision. A rounded blob for Europe and Africa, a larger irregular patch for the Americas, a distinctive shape for Australia — it comes together quickly and looks wonderful even if it’s not perfectly accurate.

Option two: Intarsia in the round. If you want the colour work to be knitted in rather than added afterwards, you can introduce your green yarn during rounds 9 to 14. This is slightly more advanced and requires careful management of your yarn floats, but the result is very clean. Plan out your continent shapes roughly before you begin and switch between your blue and green yarns as needed, always twisting the yarns around each other at colour changes to avoid gaps. Because you’re working in the round on a very small scale, this method can become a little tangled, so keep your yarn lengths short.

Option three: Embroidery. A third option is to use a simple running stitch or satin stitch to draw on continents in green. This works particularly well if you have embroidery floss rather than knitting yarn to hand, since the finer thread gives you more control over the shapes. The result has a slightly more textured, embellished look compared to duplicate stitch.

Whichever method you choose, remember that the goal isn’t cartographic accuracy — it’s a tiny knitted planet that fits in the palm of your hand. Loopy, approximate continents are part of the charm.

Attaching the Keyring

Once your planet is finished and all ends are woven in, you need to attach it to your keyring hardware. This is easier than you might think.

Thread your tapestry needle with a length of your blue yarn (about 30cm should be plenty). Locate the cast-on point at the bottom of the ball, where your yarn tail was woven in. This is typically the neatest, most discreet spot to attach your hardware.

Slide your split ring or keyring loop onto the tapestry needle before you thread through the ball. Work the needle through the centre top of the ball (the bound-off point) and pull the yarn through so the ring sits against the surface of the knitting. Work back and forth through the ball two or three times to secure the ring firmly, then tie off and weave in the end. Give the ring a gentle tug to make sure it’s secure before clipping it onto your keys.

Alternatively, if you prefer a slightly more polished finish, you can push a small loop of yarn through the top of the ball using a crochet hook, thread the keyring through the loop, and then knot the yarn securely on the inside of the ball before stuffing. This gives a slightly tidier attachment point.

Tips for a Perfect Mini Earth

A few things I’ve learned from making many, many of these over the years that will save you time and frustration.

Don’t skip the plain rows. It’s tempting when you’re eager to see the finished result to rush through the rounds without increases or decreases, but those plain knit rounds are what give the ball its satisfying roundness. Skip them and you’ll end up with something that looks more like a faceted dodecahedron than a planet.

Stuff firmly. The most common mistake beginners make is understuffing. A ball that isn’t properly filled will look lumpy and won’t hold its shape on a keyring where it’s likely to get bumped around daily. Push the stuffing in firmly and add more than you think you need before closing the top.

Use a yarn with a bit of body. A 100% acrylic DK yarn works brilliantly for this project because it has good stitch definition and holds its shape well. Very drapey or silky yarns can look a bit flat on a project this small. If you want to use a natural fibre, a wool or wool-blend DK gives excellent results.

Keep your tension consistent. Because the ball is so small, any unevenness in your tension will be immediately obvious. Try to relax your hands and knit at a consistent speed, especially around the increases and decreases.

Make a matching moon. If you’re feeling ambitious, cast on just 4 stitches instead of 6 and work a smaller version of the same pattern in pale grey or cream. A tiny moon attached to the same keyring as your earth makes for an absolutely irresistible combination.

Variations to Try

Once you’ve mastered the basic pattern, the possibilities are genuinely endless. The same construction works for any planet in the solar system, and each one is distinct and recognisable enough to be immediately charming.

Mars is a warm terracotta red with slightly darker reddish-brown patches. Jupiter is gorgeous in bands of burnt orange, cream, and brown, with a slightly larger finished size to suggest its scale. Saturn needs a ring, which you can create from a small circle of wire covered in yarn, or simply from a stiffened loop of crocheted chain. Neptune and Uranus are both stunning in different shades of blue and blue-green. Make the whole solar system and string them together as a garland — it makes a spectacular piece of nursery décor or a wonderful gift for anyone who loves space.

Beyond planets, the same ball construction works for fruits (a red apple with a tiny green leaf, a yellow lemon, a purple plum), for balls of yarn (meta and delightful), for tiny pumpkins at Halloween, and for Christmas ornaments at a miniature scale.

Making These as Gifts or to Sell

The mini earth keyring is one of those makes that photographs beautifully and appeals to an enormously wide audience. It’s the kind of thing that stops people in their tracks at a craft market, and because each one takes only an hour or two to make, it’s also practical to produce in small batches.

If you’re planning to sell them, a few practical notes. Use a good quality, colourfast yarn so the colours don’t bleed in wet weather. Make sure your keyring hardware is strong enough for daily use — cheap split rings can open under pressure, so it’s worth investing in slightly heavier gauge hardware. And consider packaging: a small recycled kraft card tag with the name of the project and your maker details adds a professional finishing touch without much extra cost or effort.

As a gift, a mini earth keyring works for almost anyone. It’s a lovely thing to make for a teacher at the end of term, for a friend who’s about to go travelling, for a new driver who needs something cheerful for their first set of keys, or for a child who loves space. It packs flat in an envelope if you need to post it, and it’s one of those handmade gifts that feels genuinely special without requiring days of effort.

A Few Words on Why I Love This Project

I think what I find most appealing about the mini earth keyring, beyond the obvious pleasure of the knitting itself, is what it represents. Carrying a tiny handmade version of our planet around with you every day is a quietly lovely thing. It’s a small reminder of where we are, of the improbable beauty of the world, and of the fact that something beautiful can be made from almost nothing — a few metres of yarn, a couple of needles, half an afternoon.

Knitting is full of projects like that. Objects that seem too small to matter but that accumulate meaning through the care put into making them. A keyring won’t change anyone’s life, but the person who receives one — or who makes one for themselves — tends to keep it for a long time. I still have the first one I ever made. It’s a little felted and bobbled now from years of daily use, but I wouldn’t swap it for anything.

I hope you enjoy making yours as much as I’ve enjoyed writing this up for you. Please do share your finished planets in the comments below or tag me on Instagram — I genuinely love seeing what everyone makes, and no two mini earths ever look quite the same. Happy knitting!
