Learn to Crochet a Super Easy Keychain (Sooo Useful!)

If you’ve been wanting to try crochet but don’t know where to start, this is your sign. A crochet keychain is one of the most beginner-friendly projects you’ll ever make — it’s small, it’s quick, and you’ll actually use it every single day. No more intimidating blankets or complicated sweaters to start with. Just a tiny, adorable accessory that you can finish in under an hour and immediately clip onto your bag or keys with pride.

In this post, I’m going to walk you through everything you need to know: the supplies, the stitches, and a full step-by-step pattern for a super easy crochet keychain that works up in minutes. Whether you’ve literally never held a crochet hook before or you’re just looking for a fast, satisfying project, this one is for you.

Why a Crochet Keychain Is the Perfect Beginner Project

Before we dive into the how-to, let’s talk about why keychains are such a genius starting point for new crocheters.

First, they’re small. Unlike a scarf that takes weeks or a blanket that seems to grow forever, a keychain is done in a single sitting. That means you get to experience the full arc of a crochet project — starting, working, finishing, and admiring your creation — all in one afternoon.

Second, they use very little yarn. You can make keychains from leftover yarn you already have or from the small amounts that come in sampler packs. No commitment to a full skein required.

Third, they’re genuinely useful. Unlike practice swatches that pile up in a drawer, a crochet keychain actually serves a purpose. It makes your keys easy to find in your bag, adds a pop of color and personality to your belongings, and makes a wonderful handmade gift for friends and family.

And finally, they help you learn fundamental crochet skills — chain stitches, single crochets, slip stitches, and working in the round — all in a tiny, low-pressure format. Once you’ve made one keychain, you’ll have the foundational knowledge to move on to bigger and more exciting projects.

What You’ll Need

One of the most delightful things about this project is how little you need to get started. Here’s your complete supply list:

Yarn: A small amount of worsted weight yarn (also labeled as size 4 medium weight) in any color you love. You’ll need less than 20 yards, so this is truly a scrap yarn project. Cotton yarn works especially beautifully for keychains because it holds its shape well and has a clean, polished look.

Crochet Hook: A size 5mm (US size H/8) hook is perfect for worsted weight yarn. If you’re using a different weight yarn, adjust your hook size accordingly — the yarn label will give you guidance on this.

Scissors: A small pair of scissors for cutting your yarn.

Yarn Needle: Also called a tapestry needle or darning needle, this is used to weave in your ends when you’re finished.

Keychain Ring: A standard metal split ring (the kind you find in craft stores, hardware stores, or online) in any size you like. Most keychains use rings between 20mm and 30mm in diameter.

Optional: Stitch markers can be helpful for keeping track of your rounds, but they’re not strictly necessary for a small project like this.

That’s genuinely it. If you’re just getting started with crochet and need to buy everything from scratch, you can put together a complete beginner’s kit for well under twenty dollars — and that kit will last you through dozens of future projects.

Understanding the Basic Stitches

If you’re brand new to crochet, don’t worry. This pattern uses only three basic techniques, and I’m going to explain each one before we get into the actual pattern.

The Slip Knot

Everything in crochet starts with a slip knot. Make a loop with your yarn so that the tail end crosses over the working yarn (the yarn connected to the skein). Insert your hook through the loop, catch the working yarn, and pull it through. Tighten gently so the loop sits snugly on your hook but can still slide. That’s your slip knot.

The Chain Stitch (ch)

With your slip knot on the hook, yarn over (wrap the yarn over your hook from back to front) and pull the yarn through the loop already on your hook. You’ve just made one chain stitch. Repeat this as many times as the pattern calls for. Chain stitches form the foundation of most crochet projects and are the building block of everything else.

The Single Crochet (sc)

The single crochet is the most fundamental crochet stitch and the one you’ll use most in this pattern. To make one, insert your hook into the designated stitch or space, yarn over, and pull the yarn through the stitch so that you have two loops on your hook. Yarn over again and pull through both loops. That’s it — one single crochet complete.

The Slip Stitch (sl st)

The slip stitch is a flat, joining stitch used to close rounds and move yarn without adding height. Insert your hook into the stitch, yarn over, and pull through both the stitch and the loop on your hook in one motion.

If you want to practice these before starting the pattern, take a few minutes just to make a chain of twenty stitches and then single crochet back across it. That five-minute exercise will make everything that follows feel much more natural.

The Pattern: Classic Round Crochet Keychain

This is a simple round keychain that looks polished and put-together. It works up into a neat little disc shape and is satisfying to make from start to finish. It’s also incredibly customizable — you can change the color, the size, add stripes, or embellish it however you like.

Finished Size: Approximately 1.5 to 2 inches in diameter, depending on your yarn and tension.

Abbreviations:

• ch = chain
• sc = single crochet
• sl st = slip stitch
• MR = magic ring (explained below)
• inc = increase (two single crochets in the same stitch)

Step 1: Start with a Magic Ring

The magic ring (also called a magic circle) is a technique that lets you start crocheting in the round without leaving a hole in the center. It sounds intimidating but it’s actually very beginner-friendly once you try it.

Wrap the yarn around your fingers twice to form a small loop. Insert your hook through the loop, grab the working yarn, and pull it through. Then chain 1. This anchors your work.

Now, single crochet 6 times into the center of the ring. After your 6th single crochet, pull the yarn tail to close the ring tight. You should have a neat, closed circle of 6 single crochet stitches.

If the magic ring is giving you trouble, there’s an alternative: chain 4 and then join with a slip stitch to form a small ring. Work your single crochets into the center of that ring instead. It will leave a very small hole in the center, but it works just as well and is a little easier for absolute beginners.

Step 2: Round 2 — Increase

Join your first round by slip stitching into the first single crochet. Chain 1 (this does not count as a stitch).

Now work 2 single crochets into every single stitch around. You’ll increase from 6 stitches to 12 stitches total.

To do this, insert your hook into the first stitch, yarn over, pull through, yarn over, pull through both loops (that’s one sc). Without moving to the next stitch, do the exact same thing in the same stitch again (that’s your second sc in the same stitch). Move to the next stitch and repeat. Continue all the way around until you’ve worked two single crochets into each of the 6 stitches from Round 1.

Slip stitch to join the round. You now have 12 stitches.

Step 3: Round 3 — Alternate Increases

Chain 1. This round follows a pattern of one regular single crochet followed by one increase (two single crochets in the same stitch).

Work 1 sc in the first stitch, then 2 sc in the next stitch. Repeat this pattern all the way around: sc, inc, sc, inc, and so on. You’ll end up with 18 stitches.

Slip stitch to join.

Step 4: Round 4 — Even Round

Chain 1. Work 1 single crochet in every stitch around. No increases this round — just a straight, even row of single crochets all the way around all 18 stitches.

Slip stitch to join. This round helps give the keychain a bit more body and substance.

Step 5: Fasten Off and Finish

Cut your yarn, leaving a tail of about 6 inches. Pull the tail through the last loop to secure it. Thread the tail onto your yarn needle and weave it carefully through several stitches on the back of the work to hide it. Trim the excess. Repeat with the starting tail from your magic ring.

Step 6: Attach the Keychain Ring

Thread the starting tail (or a fresh short piece of yarn) through the top of the keychain disc and through your split ring, then tie it securely. Alternatively, you can use a small jump ring to attach the split ring to a loop of yarn that you’ve stitched through the top of the disc.

The easiest method for beginners: fold a 6-inch piece of yarn in half, insert the folded end through a stitch at the top of your keychain disc, pull the two loose ends through the loop (this is a lark’s head knot), then thread both ends through your split ring, tie a secure knot, and weave the ends into the back of the disc. Done!

Fun Variations to Try

Once you’ve made your first keychain, you’re going to want to make about fifteen more. Here are some fun ways to mix it up:

Two-Color Stripes: Start Round 1 and 2 in one color, then switch colors for Rounds 3 and 4. Simply cut the first color when you’re ready to switch and join the new color with a slip stitch.

Mini Cactus Keychain: After finishing the disc, use green yarn to add a tiny crochet cactus on top. You can find mini amigurumi cactus patterns with a quick search, and they attach beautifully to the disc as a base.

Boho Fringe: After attaching your keychain ring, cut six to ten pieces of yarn about four inches long and attach them to the bottom of the disc using lark’s head knots. Trim them to a neat fringe. It looks amazing with a multicolor yarn.

Monogram Charm: Use embroidery floss and a needle to stitch a single letter onto the front of the disc after finishing. This makes a wonderfully personalized gift.

Granny Square Keychain: Instead of working in the round to make a disc, make a miniature granny square and attach your ring to one corner. Granny squares use the same basic stitches and add a vintage, boho feel.

Tips for Success

A few things that will make your keychain turn out beautifully, especially if you’re new to crochet:

Keep your tension consistent. Tension refers to how tightly or loosely you hold the yarn as you work. If your stitches are very tight, your work will be stiff and small. If they’re very loose, the disc will be floppy and large. Aim for something in the middle where the stitches are snug but your hook slides through them without a struggle.

Count your stitches at the end of each round. It’s easy to accidentally add or skip a stitch, and catching the mistake at the end of a round is much easier than discovering it several rounds later.

Don’t rush the magic ring. It takes most beginners two or three tries before it feels natural, and that is completely normal. If yours slips apart the first time, just try again. It gets easier every time.

Block your finished keychain if you want it to look really polished. Blocking simply means dampening the crochet piece slightly and shaping it with your hands, then letting it dry flat. Cotton yarn in particular responds beautifully to blocking.

Making It a Gift

Crochet keychains make some of the most heartfelt handmade gifts around, and because each one takes so little time and materials, you can make a set of them for everyone you love. They’re ideal as stocking stuffers, birthday add-ons, party favors, teacher appreciation gifts, and graduation presents.

To gift them beautifully, thread the keychain ring with the recipient’s initial charm (available at craft stores), choose yarn colors that match their personality or style, and slip it into a small gift bag with a handwritten note. The whole package feels personal and thoughtful in a way that something store-bought just can’t match.

If you’re feeling entrepreneurial, crochet keychains also sell wonderfully at craft fairs and on platforms like Etsy. Because they’re quick to make and use minimal materials, your cost per keychain is very low, making them a smart choice for a small handmade business.

You’re Ready to Start Crocheting

If you’ve made it to the end of this post, you have everything you need to sit down and make your very first crochet keychain today. The supplies are minimal, the stitches are simple, and the pattern is designed to be as beginner-friendly as possible while still producing something you’ll be genuinely proud of.

Crochet has a way of surprising people. What starts as a single small keychain has a tendency to turn into a full-on hobby — more yarn, more hooks, more ambitious projects, and a community of makers you never expected to find. All of that starts with one slip knot and one small loop of yarn.

So grab your hook, pick a yarn color that makes you happy, and give it a go. Your keys (and your friends) will thank you.
