10 Creative Free Crochet Keychain Patterns Using Yarn Scraps
If you have been crocheting for any length of time, you know the struggle of the yarn scrap bin. It fills up slowly but surely, one small remnant at a time, until you are staring at a colorful tangle of leftovers from every project you have ever loved. Buying new yarn feels wasteful when you have all of that perfectly good material sitting right there, but the scraps are too small for anything ambitious. That is exactly where crochet keychains come in.
Keychains are one of the most satisfying small projects a crocheter can take on. They work up in under an hour, they use almost no yarn, they make wonderful gifts, and they give you a productive reason to dig through that scrap bin rather than avoiding it. Whether you are a beginner who just learned to slip stitch or an experienced crafter looking for a quick weekend project, there is a keychain pattern here for you.
This collection of ten free crochet keychain patterns is designed to help you use up those small amounts of yarn in the most creative and charming ways possible. Each pattern has been chosen with scrap yarn in mind, meaning you do not need a full skein or even close to it. A few yards here and there are all you need. So grab your hook, empty out that scrap bin, and let’s get started.
Why Crochet Keychains Are Perfect for Scrap Yarn
Before diving into the patterns themselves, it is worth taking a moment to appreciate just how perfectly suited keychains are for scrap yarn usage. Most keychain projects require only ten to thirty yards of yarn depending on the design. That means even the tiniest scraps — the kind you feel guilty throwing away but cannot imagine using — suddenly have a purpose.
Keychains also allow you to play with color in ways that larger projects do not. Since you are working on a small scale, bold color choices and wild combinations look intentional and fun rather than overwhelming. That neon orange yarn you bought on a whim and never knew what to do with? Perfect for a keychain. The single yard of variegated wool that made it into your stash from a sample pack? It will be gorgeous on a small tassel or pompom charm.
There is also a satisfying element of completion with keychain projects. Many crafters struggle with project fatigue on larger items, setting blankets and garments aside half-finished for months or years. A keychain, on the other hand, can be started and finished in a single sitting. That sense of accomplishment is genuinely motivating, and these small finishes can give you the creative momentum to tackle bigger things.
Finally, keychains are incredibly giftable. A handmade crochet keychain costs almost nothing to make and yet feels personal and thoughtful. They are perfect as stocking stuffers, party favors, thank-you gifts, or little surprises to brighten someone’s day. When you make them from scrap yarn, you are essentially giving a beautiful handmade gift for free.
What You Will Need
For most of the patterns in this collection, you will need only a few basic supplies. A size E (3.5mm) or F (3.75mm) crochet hook works well for standard worsted weight yarn scraps, though you should always match your hook to the weight of your yarn. Lighter fingering weight scraps call for a smaller hook, usually a size B or C, while bulkier yarn looks great on a size H or larger.
Beyond your hook and yarn, you will need a few keychain rings, which are inexpensive and available at any craft store or online. A yarn needle for weaving in ends is essential, and a small amount of polyfill stuffing is helpful for any three-dimensional designs. Stitch markers come in handy for keeping track of rounds in amigurumi-style patterns, and scissors are of course a must.
Optional but useful supplies include small buttons or safety eyes for any character keychains, small amounts of wire or stiffening spray if you want your keychain to hold a particular shape, and jump rings or small lobster clasps if you want to create a more jewelry-like attachment.
Pattern One: The Classic Mini Granny Square
The granny square is arguably the most iconic motif in all of crochet, and it translates beautifully to keychain size. A single small granny square made with three or four rounds of scrap yarn creates a flat, colorful charm that looks polished and intentional.
To make this keychain, start with a magic ring and work three chain-two spaces and three double crochets into each corner for as many rounds as you like. Two rounds creates a charm about the size of a quarter, while four rounds gives you something closer to a playing card. Finish off with a border round in a contrasting color for a clean, defined edge. Attach your keychain ring by crocheting a short chain loop at one corner or by using a jump ring through a corner space. This is one of the best scrap-busting patterns of all because you can make each round in a different color, using up even single-yard scraps.
Pattern Two: The Chunky Tassel Keychain
Tassels are classic for good reason. They are elegant, tactile, satisfying to make, and they use up scraps quickly. A crocheted tassel keychain combines a small crocheted cap with a yarn tassel body for a result that looks far more sophisticated than the time it takes to create.
To make the cap, work a small circle in single crochet, increasing until you have a diameter of about one inch, then work straight for a few rows to create a cylindrical shape. Cut your tassel yarn into equal lengths — about six inches works well — and fold them over the keychain ring. Slide the crocheted cap over the folded lengths and secure it by sewing it in place. Trim the tassel ends to an even length and shake it out to fluff the fibers. The result is a boutique-quality keychain that uses only scraps.
Pattern Three: The Tiny Cactus
Few things are cuter than a tiny crocheted cactus, and this pattern works beautifully as a keychain. The basic cactus body is worked in rounds using green yarn, with a small oval base stuffed lightly with polyfill to give it a three-dimensional shape. A simple Y-shaped construction — one main column with two smaller arms attached — creates the classic cactus silhouette. Add a few straight stitches in a lighter green or yellow to suggest spines, and top the arms with tiny pink or red bobbles to represent flowers.
Attach the finished cactus to a keychain ring through a small sewn loop at the top of the main column. This is a wonderful project for using up small amounts of green yarn in any shade, and the tiny bobble flowers can come from virtually any bright scrap color you have on hand.
Pattern Four: The Rainbow Heart
Hearts are a perennial favorite in crochet, and a small crocheted heart is one of the most universally appealing keychain charms you can make. The rainbow version of this pattern works rows of color changes across a flat heart shape, giving you a reason to use up as many different scrap colors as possible.
Begin by crocheting two small circles and joining them at the top, then working down in a V-shape to form the classic heart silhouette. Work each row in a different color from your scrap pile, changing colors every one or two rows depending on how many colors you want to include. You do not need to carry the yarn up the sides — simply cut and rejoin each color, then weave in the ends with your yarn needle. Stuff the heart lightly if you want it to be three-dimensional, or leave it flat for a slimmer keychain. Either way, it is a cheerful, heartfelt charm that uses almost nothing.
Pattern Five: The Mini Mushroom
Mushroom charms have experienced an enormous surge in popularity, and it is easy to see why. They are whimsical, colorful, and endlessly customizable. A crocheted mushroom keychain consists of two parts: a white or cream stem piece worked in rounds with a flat base, and a rounded cap in your choice of color — red with white spots is classic, but any combination works beautifully.
The stem is crocheted as a small cylinder, stuffed, and closed at the top. The cap is a dome shape, also stuffed, and sewn onto the top of the stem. Use white yarn or white fabric paint to add small dots across the cap for the classic mushroom appearance. A loop sewn into the top of the cap connects the finished piece to your keychain ring. This pattern is an excellent way to use up small amounts of red, orange, yellow, blue, or purple yarn for the cap, with any neutral tone for the stem.
Pattern Six: The Simple Pom-Pom Charm
Sometimes the best approach is the simplest one. A crocheted pom-pom keychain is made by wrapping yarn around two fingers repeatedly, tying the bundle at the center with a separate piece of yarn, and then trimming the loops into a round, fluffy ball. The crocheted element comes in with a small crocheted connector — a tight tube of single crochet that both attaches to the keychain ring and holds the pom-pom securely.
The beauty of this design is that pom-poms look wonderful in mixed colors, so you can wrap multiple scrap colors together for a speckled, multicolor effect. A set of three or four pom-pom keychains in coordinating colors makes a lovely gift, and the whole set can be made in a single afternoon.
Pattern Seven: The Miniature Sunflower
A crocheted sunflower keychain is a gorgeous way to use up yellow and brown yarn scraps, and it makes a truly delightful accessory. The center of the flower is a small circle worked in dark brown or chocolate yarn, using single crochet increases to form a flat disc. The petals are worked directly into the edge of the center disc, each petal formed by chaining four or five stitches and slip stitching back down to create a pointed shape. Work one round of petals close to the center, then stagger a second round of slightly longer petals behind the first for a full, layered look.
A green single-crochet chain makes the stem, and you can add a small crocheted leaf by working an oval shape and attaching it partway down the stem. The keychain ring attaches at the top of the stem. This charming little flower brings a burst of sunshine to any keychain and uses only a handful of yards across three colors.
Pattern Eight: The Ice Cream Cone
An ice cream cone keychain is playful, nostalgic, and just tricky enough to be satisfying without being frustrating. The cone portion is worked as a triangle, either flat with single crochets or as a small three-dimensional cone shape. The ice cream scoop is a simple sphere worked in the round, stuffed firmly, and sewn to the top of the cone.
The fun part is the customization. Swap yarn colors to create any flavor you like — pale pink for strawberry, lavender for blueberry, minty aqua for pistachio, or rich chocolate brown. Add a few French knots or straight stitches in contrasting colors to suggest sprinkles. A small drizzle of chain stitches in a contrasting color creates the look of sauce or syrup. Finish with a loop at the top of the scoop for your keychain ring. This pattern is a particular hit with children and works beautifully as a school bag charm.
Pattern Nine: The Striped Cylinder
Not every keychain needs to be a character or a recognizable shape. A simple striped cylinder, worked in the round with color changes every few rows, creates a stylish and modern keychain charm that suits any aesthetic from minimalist to maximalist depending on your color choices.
Work the cylinder in single crochet, changing colors every two rows for bold, defined stripes or every single row for thinner, more graphic stripes. For a color-blocked look, work each color for six or eight rows before switching. Close the cylinder at both ends with decreasing rounds, stuff it lightly, and attach a keychain ring through a loop at one end. This is one of the most versatile patterns in the collection because the same basic construction looks completely different depending on the colors you choose, meaning you could make dozens of these keychains from your scrap bin and each one would be unique.
Pattern Ten: The Mini Amigurumi Bear
Saving the most ambitious pattern for last, a tiny amigurumi-style bear keychain is a wonderful project for crafters who want to stretch their skills while still using up scrap yarn. The basic construction uses standard amigurumi techniques: magic rings, single crochet in the round, and careful increases and decreases to shape the body, head, and ears.
The body is a small oval, the head is a slightly larger sphere, and the ears are tiny circles sewn onto the sides of the head. Safety eyes or small embroidered French knots give your bear character, and a simple embroidered nose and smile complete the face. A keychain ring attaches to the top of the head or through a small loop sewn into the bear’s back. The entire bear can be made from as little as twenty yards of a single color, with a small amount of a contrasting color for details.
Tips for Making the Most of Your Scrap Yarn Keychains
A few practical notes will help ensure that your finished keychains are polished and durable. Always weave in your ends thoroughly — a keychain that gets daily use will experience more friction and movement than a decorative piece, so loose ends can unravel over time. A small drop of fabric glue on each woven end adds extra security without affecting the appearance of the finished piece.
When choosing yarn for keychains, consider durability as well as aesthetics. Cotton and acrylic yarns hold up particularly well with frequent handling and can be spot-cleaned easily. Wool is beautiful but slightly more delicate and can pill with rubbing. If you have both fiber types in your scrap bin, save the wool for keychains that will be display pieces or gifts, and use acrylic for everyday carry keychains.
Blocking your finished keychains can make a significant difference in their appearance, especially for flat pieces like the granny square or the heart. A quick steam block or a gentle wet block followed by pinning to shape while drying will give your work a crisp, professional finish.
Finally, consider turning your keychains into a small side business or gifting collection. A dozen varied keychains made over the course of a few evenings can fill a basket for a craft fair, a collection for holiday gifts, or a donation to a school fundraiser. They are small objects with a generous spirit, and that is exactly what makes them so satisfying to create.
Final Thoughts
Crochet keychains are proof that beautiful things can come from small beginnings. Every scrap of yarn in your bin has potential — potential for color, for texture, for character, for charm. These ten free patterns give you a starting point, but the real magic happens when you start mixing and matching ideas, combining elements from different patterns, and experimenting with the unique scraps you have on hand.
The granny square can become a heart. The mushroom can wear a rainbow cap. The amigurumi bear can carry a tiny tassel. Your scrap bin is not a collection of leftovers — it is a palette full of possibilities. Pick up your hook and start turning those loose ends into something worth holding onto.
