10 Creative Free Crochet Keychain Patterns Using Yarn Scraps
If you’ve been crocheting for any length of time, you know the struggle: a growing pile of leftover yarn that’s too small to use for a full project but too pretty to throw away. Those little balls and partial skeins of yarn scraps deserve a second life, and one of the best ways to give it to them is by crocheting keychains. These tiny, satisfying projects are quick to finish, practical to use, and make genuinely thoughtful handmade gifts. Best of all, they don’t require a pattern book or a trip to the craft store — just your scraps, a hook, and a little creativity.
In this post, we’re walking through 10 creative free crochet keychain patterns that you can make entirely from yarn scraps. Whether you’re a beginner looking for a low-stakes project to practice new stitches or an experienced crocheter wanting to use up every last yard of that gorgeous hand-dyed yarn, there’s something here for you. Each pattern uses minimal materials, works up in under an hour, and can be customized endlessly with whatever colors you have on hand.
Let’s dig into those yarn scraps and get crocheting.
Why Keychains Are the Perfect Scrap Yarn Project
Before we jump into the patterns themselves, it’s worth taking a moment to appreciate just how perfectly suited keychains are for scrap yarn. Most keychains require only a few yards of yarn — sometimes as little as five or ten — which means even the tiniest leftover bits are fair game. You can work through an entire rainbow of odds and ends in a single afternoon and end up with a collection of cheerful, useful accessories.
Keychains are also a brilliant way to practice new techniques without committing to a large project. Want to try amigurumi-style shaping? Make a tiny crochet strawberry keychain. Curious about working in the round? A mini donut or cactus is a perfect introduction. Every pattern on this list doubles as a skill-building exercise, which makes your practice time productive in a very tangible, keep-it-in-your-pocket kind of way.
And let’s not overlook the gift angle. Handmade keychains are the kind of small, personal gift that people genuinely love receiving. They’re useful enough to actually get used, small enough to make in quantity, and personal enough to feel special. If you’re heading into a holiday season or a birthday crunch, a handful of these patterns and your scrap bin can take care of a lot of your gift list.
What You’ll Need for Most of These Patterns
Before you start, gather a few basic supplies that will serve you across almost all of these patterns. You don’t need anything fancy.
For yarn, worsted weight scraps work well for most of these designs, giving you a nice chunky result that’s easy to work with. That said, many of these patterns adapt beautifully to lighter weight yarns if you adjust your hook size accordingly. Fingering or DK weight scraps will produce more delicate, miniature-looking results, which can be just as charming.
You’ll want a crochet hook in a size appropriate for your yarn — typically a 4mm or 5mm hook for worsted weight. A tapestry needle for weaving in ends is essential, as is a small amount of polyester fiberfill stuffing for any of the three-dimensional patterns. You’ll also need keychain rings, which are inexpensive and available at any craft store or online in bulk packs. A split ring or lobster clasp style both work well. Finally, keep scissors and stitch markers handy.
1. The Classic Granny Square Keychain
The granny square is one of crochet’s most iconic motifs, and scaling it down to keychain size is a wonderful way to use up tiny scraps of multiple colors at once. A single tiny granny square uses almost nothing — you can make the center round from a leftover six inches of yarn and build outward with whatever colors you have.
To make this keychain, work a standard granny square pattern but stop after two or three rounds, keeping the finished square small enough to sit comfortably in the palm of your hand. Once your square is finished, you can either leave it flat and attach it directly to a keychain ring, or make two matching squares and join them with a simple slip stitch border, leaving a small opening to stuff lightly before closing. This gives you a little pillow-style keychain that’s satisfyingly three-dimensional.
The beauty of this pattern is that no two will ever look the same. Use up all your odds and ends, changing colors every round, and embrace the scrappy, patchwork look. This is a genuinely zero-waste pattern.
2. The Mini Cactus Keychain
Everyone loves a cactus, and the mini crocheted version is almost unreasonably cute. This pattern works in the round to create a tiny barrel cactus shape, which you then stuff lightly and finish with a simple embroidered texture to suggest the cactus’s characteristic spines. You need green yarn for the body, a tiny bit of pink or yellow for a flower on top if you like, and a small scrap of brown for the pot.
Start with a magic ring and increase in each stitch around to create your base circle. Work several rounds even, then decrease back down to close the top, leaving an opening to stuff before you finish. For the pot, crochet a small cylinder in brown or terra cotta, stuff the cactus body into it slightly, and secure with a few stitches. Add a simple chain loop at the top for the keychain ring.
This is a wonderful beginner amigurumi project. The cactus’s simple cylindrical shape is very forgiving, and the embroidered details can be as minimal or as elaborate as you like.
3. The Tiny Taco Keychain
Yes, a taco. Crocheted food keychains have been wildly popular for years, and the taco is a perennial favorite because it’s surprisingly simple to construct and absolutely delightful to carry around. You’ll need tan or yellow yarn for the shell, green for lettuce, red for tomato, and brown for the “meat” — though of course you can make your taco as colorful and creative as you like.
The shell is worked as a simple oval or half-circle, then folded and joined along the bottom edge to create the taco shape. The fillings are small crocheted pieces in contrasting colors layered inside the shell before it’s closed. Once assembled, a chain or jump ring at the top completes the keychain. The result is a tiny, cheerful taco that is absolutely guaranteed to make people smile.
4. The Boho Tassel Keychain
If you want something quick, this is your pattern. A tassel keychain uses almost no crochet at all — but the crocheted cap at the top is what elevates it from a simple tassel to a handmade accessory. Cut your yarn scraps into equal lengths, fold them in half, and attach them through a ring to create the tassel body. Then crochet a small, tight cylinder that fits over the folded top of the tassel and serves as a decorative cap.
You can work the cap in a single color or stripe it with several different yarns for a boho, layered look. Add beads to individual strands before attaching for extra texture and movement. These keychains take about fifteen minutes to make and use up the very shortest, most unusable-seeming scraps. They’re also endlessly customizable — change the length, mix colors freely, or add a braided or knotted element above the tassel cap.
5. The Mini Donut Keychain
A crocheted donut keychain is one of those projects that looks more complicated than it is. The donut shape is achieved by working in continuous rounds around a central ring, which you can accomplish by crocheting around a plastic ring or by working a tube and then joining the ends together. Either method produces a satisfyingly round, plump little donut.
Use tan or beige yarn for the donut base, then add a “frosting” layer on top in pink, chocolate brown, white, or any color you like. You can crochet the frosting as a flat piece that sits on top of the donut and secure it with a few stitches, or work it in with surface slip stitches for a more integrated look. Finally, add tiny embroidered “sprinkles” in contrasting colors using a tapestry needle and your smallest scraps. The result is a tiny, realistic-looking donut that people will absolutely adore.
6. The Geometric Diamond Keychain
For something with a more modern, graphic feel, the geometric diamond keychain delivers clean lines and a sophisticated look that doesn’t scream “craft project” in the way some of the more playful designs do. This pattern uses a simple combination of double crochet and chain stitches to create a small diamond or rhombus shape, worked flat and either left as a single layer or doubled up for thickness.
The diamond shape works particularly well in a single bold color or in a two-tone colorblock arrangement. Try working the top half in one scrap color and the bottom half in another, or add a contrasting border around the entire shape. This is a great pattern for those sophisticated hand-dyed or variegated yarn scraps that deserve to be shown off rather than buried in a stuffed animal or a background color.
7. The Strawberry Keychain
The crocheted strawberry is a classic for good reason — the shape is simple, the result is adorable, and the pop of red against the green leaves makes for a very satisfying color combination. You’ll need red yarn for the body, green for the leaves and stem, and a tapestry needle to add small yellow seed details with embroidery.
Work the strawberry body from the top down, starting with increases to shape the rounded top and then decreasing more steeply toward the pointed bottom tip. Stuff lightly as you go to maintain the shape. The leaves are worked separately as a small flower-like shape and attached to the top, with a short chain added for the stem and keychain attachment. This is one of the most photogenic keychains on this list and makes a beautiful gift, especially when made in a set with other small fruit designs like tiny lemons or blueberries.
8. The Rainbow and Cloud Keychain
This whimsical design is made of two separate pieces — a small crocheted cloud and a tiny rainbow — that are attached together and finished with a single keychain ring. The cloud is a simple white or cream puff worked in clusters or bobble stitches to give it a fluffy texture. The rainbow is several short arcs worked in different colors, layered and stitched together, then attached to the bottom of the cloud.
This is a wonderful project for using up the absolute tiniest scraps of yarn, since each arc of the rainbow requires only a very small amount of a single color. Red, orange, yellow, green, blue, and purple — you can raid the very bottom of your scrap bin and put it all to good use. The finished keychain is cheerful, optimistic, and very popular with kids and adults alike.
9. The Initials Letter Keychain
A personalized letter keychain is one of the most thoughtful gifts you can make, and it’s more achievable than it might sound. There are two main approaches: you can work a small flat square or rectangle and use embroidery or surface slip stitches to add the letter on top, or you can actually crochet the letter itself as a three-dimensional shape using a very tight tension and stuffing it as you go.
The surface embroidery approach is the easiest and most accessible for beginners. Work a small rectangle in a solid color, then use a tapestry needle and a contrasting yarn to stitch a simple block letter onto the surface. The three-dimensional letter approach takes more patience but produces a wonderful result — each finished letter keychain looks like a tiny sign. Both versions make excellent personalized gifts, especially when paired with complementary colors chosen for the recipient.
10. The Colorblock Heart Keychain
We’ll close out this list with a heart, because it’s hard to top the classic crocheted heart for a combination of simplicity and impact. The colorblock version adds a modern twist by working the heart in two distinct colors — either split horizontally across the middle or divided vertically down the center — creating a graphic look that feels fresh rather than overly sentimental.
The basic crocheted heart is worked by making two separate bumps (essentially two small circles) and then joining them together while working down to a point. The decreases on either side of the center dip and at the bottom point give you the recognizable heart shape. For the colorblock version, simply change your yarn color at the midpoint of the heart.
This pattern is wonderfully fast — a heart keychain can be finished in under half an hour — and makes an excellent last-minute gift for Valentine’s Day, Mother’s Day, or anytime you want to give someone a small reminder that you were thinking of them.
Tips for Making Your Crochet Keychains Last
Once you’ve made your keychains, a few finishing steps will help them hold up well over time. Weave in your ends very securely, going through several different directions rather than just back and forth, since keychains take a lot of daily handling and pulling. If you want extra security, a tiny dot of fabric glue on your woven ends can help.
For stuffed keychains, make sure your stuffing is firm enough that the piece holds its shape, but not so packed that it distorts the crocheted fabric. A little goes a long way with fiberfill.
Attach your keychain ring through a reinforced loop whenever possible. If your pattern ends with a simple chain loop, work several slip stitches through that loop to strengthen it before attaching the ring, or add a jump ring between the crocheted piece and the keychain hardware to distribute the wear.
Start Working Through That Scrap Bin
There’s something genuinely satisfying about transforming a chaotic pile of yarn scraps into a collection of tiny, polished, usable accessories. These ten patterns barely scratch the surface of what’s possible with scrap yarn and a small hook, but they’re a wonderful place to start. Work through one pattern, then another, and before long you’ll find that your scrap bin is looking a little more manageable — and your keychain collection is looking a lot more colorful.
Whether you’re making these for yourself, gifting them to friends, or selling them at craft fairs, crochet keychains are one of those quiet, humble projects that deliver an outsized amount of joy for the time and materials they require. Grab your scraps, pick a pattern, and get started.
