10 Creative Free Crochet Keychain Patterns Using Yarn Scraps
If you’ve been crocheting for any length of time, you know the feeling well. You finish a project, whether it’s a cozy blanket, a market bag, or a pair of slippers, and you’re left with a little pile of yarn scraps that feel too precious to throw away but too small to do much with. Those little leftovers have a habit of accumulating in bags, bins, and baskets until you’re practically swimming in them.
Here’s the good news: crochet keychains are one of the most satisfying and practical ways to put those scraps to work. They’re quick, they’re beginner-friendly, they make wonderful gifts, and they cost next to nothing when you’re working with yarn you already have. In this post, we’re sharing ten creative free crochet keychain patterns that will help you use up your stash, clear out your scrap pile, and end up with something genuinely charming to show for it.
Whether you’re new to crochet or you’ve been hooking for years, these patterns are designed to be approachable and fun. Most of them take less than an hour to complete, which makes them ideal for evenings when you want to craft without committing to a big project. Let’s dig in.
Why Crochet Keychains Are the Perfect Scrap Project
Before we get into the patterns themselves, it’s worth talking about what makes keychains such a smart use of leftover yarn. First and foremost, they’re small. A typical crochet keychain uses anywhere from just a few yards to maybe twenty or thirty yards of yarn, which means even the tiniest scrap can become something beautiful.
They’re also incredibly versatile in terms of yarn weight. Most keychain patterns work with any weight from fingering to bulky, as long as you adjust your hook size accordingly. This is huge when your scrap bag contains a chaotic mix of different yarns that don’t match anything else you’re working on.
Keychains are also a fantastic way to practice new stitches or techniques without the pressure of a larger project. Want to try your first amigurumi? A keychain-sized creature is the perfect starting point. Curious about the bobble stitch or the magic ring? A keychain is a low-stakes way to experiment.
And finally, they make wonderful gifts. A handmade keychain feels personal and thoughtful, and because they’re so quick to make, you can batch a dozen of them for holiday gifts, party favors, or teacher appreciation days without spending a fortune or losing your mind.
What You’ll Need to Get Started
For most of the patterns below, you’ll want to have a few basic supplies on hand. A set of crochet hooks in various sizes will serve you well since you’ll be working with different yarn weights. A pair of sharp scissors is essential, along with a yarn needle for weaving in ends. For the finishing touch, you’ll need keychain rings, which are inexpensive and available at craft stores or online in bulk.
Optional but helpful supplies include stitch markers, fiberfill stuffing for any three-dimensional designs, and split rings or lobster clasps if you want your keychains to be easily removable. A little bit of fabric glue or clear nail polish can also help secure knots if you want extra durability.
Now, let’s get into the patterns.
1. The Classic Granny Square Keychain
Few things in crochet are as iconic as the granny square, and scaling one down to keychain size is an absolutely delightful project. Work a small three-round granny square using two or three colors of scrap yarn, stiffen it slightly if you like with liquid starch, and attach a keychain ring through one corner. You can make a matched set in coordinating colors or go wild with scraps in completely mismatched shades for an eclectic, boho look.
The beauty of this pattern is that if you already know how to make a granny square, you already know how to make this keychain. The stitch pattern is exactly the same, just executed on a smaller scale. A single round of chain three spaces with double crochets in the corners is all it takes to create the classic look. For a finished keychain, three rounds is typically the sweet spot for a nicely proportioned piece.
Tip: Use a slightly smaller hook than the yarn label recommends. This creates a tighter fabric that holds its shape better and looks crisper as a keychain.
2. The Mini Amigurumi Bear
Amigurumi, the Japanese art of crocheting tiny stuffed figures, might look intimidating, but a mini bear keychain is one of the most beginner-friendly amigurumi projects you can find. The body is worked in continuous rounds in single crochet, and the entire project typically uses less than fifteen yards of yarn even in a worsted weight.
You’ll crochet a small sphere for the head, attach tiny round ears, and add a simple oval body. A keychain ring goes through a small loop crocheted at the top of the head. Embroider simple eyes with a contrasting yarn color, or use tiny safety eyes if you have them. A French knot nose finishes the face beautifully.
This is an especially lovely project to work in neutral tones like cream, tan, or grey, but bright scraps of color make for cheerful little characters too. Make a whole family of them in different shades.
3. The Strawberry Keychain
This is one of those patterns that looks incredibly complicated but is actually very straightforward. The strawberry shape is worked from the top down in red yarn using single crochets worked in the round, with a little fiberfill stuffed inside for dimension. Green chain loops or a crocheted leaf cap sits at the top to complete the illusion.
The seeds can be embroidered with yellow yarn using small straight stitches scattered across the surface, which takes just a minute or two but makes a huge difference in how realistic the finished strawberry looks. A green chain attached to the keychain ring mimics the stem.
Because the body uses only red and the leaf uses only green, this is a perfect pattern for using up even the smallest amounts of yarn. It’s also enormously popular and photogenic, making it a great project if you share your makes on social media.
4. The Tassel Keychain
Tassels are one of the simplest and most satisfying things you can make with yarn scraps, and they make genuinely stylish keychains that look like something you’d buy in a boutique. Cut lengths of yarn, fold them over a keychain ring, wrap the top tightly with a contrasting color to create the tassel head, and you’re done.
The beauty of the tassel is that it requires zero crochet skills for the basic version, but you can elevate it significantly by crocheting a decorative bead or cap for the tassel head. A simple crocheted sphere worked in the round with a slip stitch closure gives you a polished, professional-looking result. You can also wrap the tassel head in multiple colors for a striped effect, or mix yarn weights within the tassel itself for interesting texture.
Tassels look especially beautiful when made with gradient or ombre yarn scraps, where the colors shift from one shade to another as they hang.
5. The Rainbow Heart Keychain
A flat heart worked in the classic heart-shaped crochet pattern makes a sweet and simple keychain that’s perfect for Valentine’s Day gifts or just everyday carrying. Use a single color for a clean look, or work each row in a different scrap color to create a miniature rainbow heart that uses up the tiniest lengths of leftover yarn.
The pattern typically starts with a chain of about twelve stitches and builds up into the recognizable heart shape using half double crochets and decreases. The finished piece is flat, which makes it easy to attach a keychain ring through the top dip of the heart.
This is a wonderful project to make in pairs, giving one to a friend or loved one and keeping the other for yourself.
6. The Crochet Coin Purse Keychain
This one is slightly more ambitious than the others on this list, but it’s still well within reach for intermediate beginners. A tiny coin purse worked in the round creates a functional little pouch that clips onto your keys. It’s perfect for keeping a few emergency bills, a couple of ibuprofen, or a spare hair tie handy.
Work the base as a flat oval, then join it into a tube and crochet upward until you have a small pouch of the desired height. A simple drawstring closure at the top using a length of chain crochet keeps everything secure. The keychain ring attaches through a loop at the side seam.
For best results, use a cotton yarn scrap, which creates a sturdier fabric with less stretch. Variegated cotton scraps look especially lovely with this pattern because the color shifts create an interesting visual effect even in such a small piece.
7. The Ghost or Pumpkin Seasonal Keychain
Seasonal keychains are incredibly fun to make and gift, and two of the quickest to whip up are the ghost and the pumpkin, both of which require almost no yarn and very little time. The ghost is simply a small amigurumi sphere with a ruffled or wavy bottom, worked in white yarn with embroidered black eyes. The pumpkin is an oval shape pinched into segments with a length of yarn pulled through the center, with a tiny brown stem and green leaf on top.
These patterns are fantastic for using up orange, white, and brown scraps that might not have obvious homes otherwise. Make a batch of them in October for trick-or-treaters or as Halloween party favors. The pumpkin shape can also be adapted into a Christmas ornament with red yarn and a green stem, or a watermelon slice with green, white, and red stripes.
8. The Initial or Monogram Keychain
A crocheted letter or monogram keychain makes one of the most personalized gifts imaginable. These are typically worked in intarsia or as a flat shape following a letter template, then stiffened slightly with liquid starch or a light spray of fabric stiffener to help them hold their shape.
If graphwork feels daunting, an easier approach is to crochet a small rectangle or circle as a backing and embroider the initial on top using a contrasting color of yarn. This gives you a clean, flat keychain with a handmade feel that looks polished rather than homemade.
Alternatively, look for free crochet alphabet letter patterns, which are widely available and typically designed to be worked flat in single or half double crochet. Worked on a small scale, a single letter makes a charming keychain with minimal yarn use.
9. The Cactus Keychain
The cactus keychain has become a perennial favorite in the crochet community, and for good reason. It’s adorable, it’s whimsical, and it makes use of those stubborn little bits of green yarn that accumulate from blanket borders and dishcloth projects. The basic shape is an oval body with one or two smaller oval arms attached at the sides, all worked in single crochet in the round with a little stuffing inside.
The texture of a cactus lends itself beautifully to creative embellishment. You can add small straight stitches in a slightly darker or lighter green to mimic the ridges of a real cactus, or use a strand of brown yarn to create tiny spine details. A tiny flower worked in pink, yellow, or red yarn and perched on top of the cactus makes the whole piece irresistibly cute.
Pot up your crochet cactus in a tiny crocheted terracotta-colored base if you want to take it to the next level, though the cactus alone works perfectly well as a standalone keychain.
10. The Mini Yarn Skein Keychain
This one is a favorite among crafters because it’s meta in the most delightful way: a tiny crocheted yarn skein to hang from the keys of someone who loves to crochet or knit. It’s a perfect gift for a crafty friend and a wonderful way to use up a single color of leftover yarn since the entire project is worked in one shade.
The shape is essentially a small oval or cylinder that’s worked in the round, then cinched in the center with a few wraps of yarn to create the classic skein silhouette. A length of contrasting yarn can be used to wrap a few times around the cinched center, mimicking the tie that holds a real skein together. The keychain ring attaches through a loop at the top.
This pattern also works beautifully in gradient or hand-dyed yarn scraps, where the color variation mimics the look of a real artisan skein. It’s quick, it’s clever, and it will make any yarn lover smile.
Tips for Finishing Your Keychains Beautifully
No matter which patterns you choose, a few finishing tips will help your keychains look their best. Always weave in your ends thoroughly, going through several stitches in different directions to prevent unraveling. For amigurumi-style keychains that will be handled frequently, a tiny drop of fabric glue on the woven ends adds extra security.
When attaching your keychain ring, make sure the connection point is strong. Working several slip stitches or single crochets around the ring before attaching it to your piece creates a more durable join than simply threading the ring through a stitch. If you’re giving the keychain as a gift or expect it to get heavy daily use, consider using a split ring rather than a simple keychain loop, as split rings hold up better over time.
Blocking is optional for keychains but can make a noticeable difference for flat pieces like granny squares and hearts. A light spritz of water and a gentle reshaping before drying will give you crisp edges and a more polished result.
Making the Most of Your Scrap Yarn
One final thought before you dive into your first project: don’t stress too much about matching the exact yarn weight or color called for in any pattern. Keychain patterns are wonderfully forgiving. If the yarn you have is slightly thicker, just go up a hook size. If your scraps are thinner, go down a size. The result might be a little bigger or smaller than the original, but it will still be charming and useful.
The whole point of a scrap project is to work with what you have. So open up that bag of leftovers, pick the colors that catch your eye, and start making something wonderful. Your keys will thank you.
Happy hooking!
