Quick Crochet Project | Easy Octopus Keychain

If you’ve been looking for a fun, fast, and absolutely adorable crochet project, you’ve landed in exactly the right place. This easy octopus keychain is the kind of project that hooks you from the very first stitch — pun very much intended. Whether you’re a beginner who just learned how to hold a crochet hook or an experienced crafter looking for a quick weekend win, this little guy is perfect for you. He works up in under an hour, uses only a tiny bit of yarn, and makes the most charming bag charm, keychain, or gift you can imagine.

Let’s dive into everything you need to know to make your own crocheted octopus keychain, from the materials list all the way through finishing touches and styling ideas.

Why You’ll Love This Project

Before we get into the pattern itself, let’s talk about why this little project is worth your time — because trust me, it absolutely is.

First, it’s genuinely quick. Unlike larger amigurumi projects that require days of work and a mountain of yarn, this octopus keychain can be completed in a single sitting. That makes it perfect for crafters who want the satisfaction of finishing something without committing to a weeks-long project.

Second, it’s incredibly beginner-friendly. The entire pattern is built on just a few basic stitches: the magic ring, single crochet, increase, decrease, and slip stitch. If you know those, you’re already halfway there. And if you’re still learning, this project is a wonderful place to practice them in a low-stakes, forgiving format.

Third, octopuses are universally beloved. There’s something about their round little heads and wiggly tentacles that makes people smile. The finished keychain has a plump, satisfying shape and those little legs dangle in the most delightful way when attached to a bag or keys. They make wonderful gifts for kids, teens, and adults alike. You can make a batch of them in a single afternoon and give them out as party favors, stocking stuffers, or just-because gifts.

Fourth, the project is highly customizable. You can make them in any color imaginable, add embroidered details, tiny crocheted accessories, or change the expression on their face to make each one unique. Once you’ve made one, you’ll likely want to make ten more.

Materials You’ll Need

One of the best things about this project is that it uses very little material. You probably already have most of what you need sitting in your craft stash.

For yarn, you’ll want a small amount of worsted weight yarn in your main color. Worsted weight works beautifully here because it gives the octopus a satisfying, solid structure without being too stiff. You’ll need roughly 15 to 20 yards, which means this is a great stash-buster project. You can also use DK weight yarn with a slightly smaller hook for a more delicate finished product, but worsted weight is the most forgiving for beginners.

For safety eyes, you’ll need two 6mm or 9mm black safety eyes. The size you choose will change the overall expression of your octopus — smaller eyes give a more compact, serious look, while larger ones make your octopus look wide-eyed and curious. Both are adorable. If you’re making this for a small child, skip the safety eyes and embroider the eyes with black yarn or embroidery floss instead, as safety eyes can be a choking hazard.

You’ll also need a 4mm crochet hook, which pairs perfectly with worsted weight yarn, a tapestry needle for weaving in ends and sewing pieces together, a small amount of polyfill stuffing or fiberfill to fill the head, a pair of scissors, and a keychain ring or lobster clasp to attach to the finished octopus.

Optional but nice to have: black embroidery floss or yarn for adding a smile or other facial details, and stitch markers to help you track your rounds.

Understanding the Basic Stitches

If you’re relatively new to crochet and want a quick refresher before diving in, here’s a brief overview of the stitches you’ll be using throughout this pattern.

The magic ring (also called a magic circle) is the foundation of most amigurumi work. It allows you to start crocheting in the round without leaving a hole in the center of your work. To make one, wrap the yarn around your fingers to form a loop, insert your hook, pull up a loop of working yarn, and chain one to secure. Then crochet your first round of stitches into the ring before pulling the tail end tight to close the hole.

A single crochet is the most fundamental stitch in amigurumi. Insert your hook into the stitch, yarn over, pull through, yarn over again, and pull through both loops on the hook.

An increase means you’ll work two single crochets into the same stitch, adding a stitch to your total count and making your piece wider.

A decrease (most commonly an invisible decrease in amigurumi) means you’ll combine two stitches into one, reducing your stitch count and pulling your work inward. To do an invisible decrease, insert your hook into the front loop only of the next stitch, then the front loop only of the stitch after that, yarn over and pull through both front loops, then yarn over and pull through the remaining two loops on your hook.

A slip stitch is used to join rounds or move across stitches without adding height. Insert your hook, yarn over, and pull through both the stitch and the loop on your hook in one motion.

The Pattern: Easy Crochet Octopus Keychain

Finished Size

The finished octopus will measure approximately 2.5 to 3 inches tall when the tentacles are hanging down, and about 1.5 inches wide across the head. Sizes may vary slightly depending on your tension and yarn weight.

Abbreviations

Throughout the pattern, the following abbreviations are used: MR = magic ring, SC = single crochet, INC = increase (2 SC in same stitch), DEC = invisible decrease, SL ST = slip stitch, CH = chain, and ST = stitch.

Part One: The Head

Start by making a magic ring and chain one.

Round 1: Work 6 SC into the magic ring. Pull the tail to close the ring. (6 stitches)

Round 2: INC in each stitch around. (12 stitches)

Round 3: SC 1, INC repeat around. (18 stitches)

Round 4: SC 2, INC repeat around. (24 stitches)

Rounds 5 through 8: SC in each stitch around for 4 rounds. (24 stitches each round)

This is the point where you’ll want to attach your safety eyes. Place them between rounds 5 and 6, with about 6 to 8 stitches of space between them. Once they’re positioned the way you like, snap the washers onto the backs to secure them permanently. If you want to add a smile with embroidery floss, you can do that now or after stuffing — either approach works.

Round 9: SC 2, DEC repeat around. (18 stitches)

Round 10: SC 1, DEC repeat around. (12 stitches)

Now stuff your octopus head firmly with polyfill. You want it to feel round and full, but not so stuffed that your stitches are being stretched apart. A little goes a long way here.

Round 11: DEC around. (6 stitches)

Fasten off, leaving a tail. Use your tapestry needle to weave through the remaining 6 stitches and pull tight to close the hole completely. Weave in this end.

Part Two: The Tentacles

The tentacles are what really make this octopus come alive. You’ll make 8 of them, which is anatomically accurate and also just looks perfect. Each tentacle is a simple chain with single crochets worked back along it.

To make one tentacle, attach your yarn to the bottom edge of the head. Chain 12. Then, starting from the second chain from the hook, single crochet back along the entire chain. When you reach the end, slip stitch into the base of the head to secure the tentacle. Fasten off and weave in the end, or continue to the next tentacle placement without fastening off if you prefer a more seamless approach.

Repeat this process 7 more times, spacing the tentacles evenly around the bottom of the head. To get even spacing, divide the bottom edge into 8 sections before you start. You can use stitch markers to mark every third stitch around the base as a guide.

Once all 8 tentacles are attached and secure, the octopus will really start looking like himself. The chain-based tentacles have a gentle curl to them, which gives a wonderful organic, wiggly look.

Part Three: Adding the Keychain Ring

To attach the keychain ring, cut a 6-inch piece of yarn in your main color. Thread it through the top of the octopus head at the very center point. Fold the yarn in half and knot both ends together to create a small loop. Slip your keychain ring or lobster clasp through this loop before tightening the knot. Trim any excess and use a tapestry needle to hide the ends inside the head so they aren’t visible from the outside.

Alternatively, you can use a piece of thin cord, jewelry wire, or a small jump ring for a more polished, professional look. If you plan to sell these or give them as gifts, a metal lobster clasp with a split ring looks especially nice and holds up to daily use.

Tips for a Perfect Octopus Every Time

A few small details make a big difference in the final result, so here are some tips gathered from making many of these little creatures.

Work in continuous rounds rather than joining each round with a slip stitch. This is the standard approach for amigurumi and gives you a seamless look without a visible seam line running up the side of your work.

Use a stitch marker to keep track of where each round begins and ends. Since you’re working in continuous rounds, the start of each round can get confusing quickly. Simply move the marker up as you complete each round.

Stuff the head firmly. An understuffed octopus head will look slightly deflated and sad, while a properly stuffed one looks plump and cheerful. Err on the side of a little more stuffing rather than less.

Experiment with facial expressions. The placement of the safety eyes changes the entire personality of your octopus. Eyes placed close together and slightly lower on the face give a sleepy, content look. Eyes spaced farther apart give a more wide-awake, curious expression. You can also add a tiny embroidered smile using a simple straight stitch or a curved backstitch.

Try different yarn textures. Cotton yarn gives a crisp, clean finish that works beautifully for keychains since it holds its shape well. Acrylic yarn is soft, widely available, and comes in a stunning range of colors. Wool or wool blend yarn gives a cozy, slightly fuzzy look that’s particularly charming. Don’t be afraid to experiment.

Color Ideas and Inspiration

One of the most fun parts of making octopus keychains is choosing the colors. Here are some combinations that work especially well.

Classic ocean colors like teal, seafoam, coral, and navy are always popular and have a natural, cohesive feel. A deep teal octopus with white eyes looks absolutely stunning and has a slightly mysterious, ocean-depth vibe.

Pastel shades like lavender, pale pink, mint, and baby yellow make the sweetest keychains and are hugely popular for gifts. A pastel rainbow set — one octopus in each color — makes a wonderful gift basket for a crochet-loving friend.

Bold, bright colors like neon yellow, hot pink, electric blue, and bright orange make keychains that are easy to spot in a crowded bag, which is actually incredibly practical in addition to being fun.

Halloween-themed octopuses in black, orange, and purple are a huge hit for seasonal crafting. Christmas-colored ones in red and green with a tiny white belly are equally charming.

You can also make multicolored octopuses by changing yarn colors midway through the head or by using variegated yarn, which creates a beautiful self-striping or speckled effect without any color changes required on your part.

How to Make Them Faster

If you’ve caught the octopus-making bug and want to churn out a whole batch, here are a few strategies for speeding up your production.

Work on multiple octopuses at once in an assembly line style. Make all of the heads first, then go back and attach all of the tentacles, and finally add all of the keychains. This approach keeps your hands in the same motion for longer stretches and tends to be faster overall than finishing one complete octopus before starting the next.

Pre-cut your polyfill into small balls before you start. This means you’re not stopping mid-project to tear off stuffing, which breaks your rhythm.

Use a yarn bowl or another way of controlling your yarn tension so it feeds smoothly without tangling. Stopping to untangle yarn is one of the biggest time-wasters in any crochet project.

Keep a dedicated small project bag with all of your octopus-making supplies already inside. This way you can pick it up and start crocheting immediately without hunting for your hook or scissors.

Gifting and Selling Your Octopus Keychains

These little octopuses are incredibly popular at craft fairs and markets. They tend to sell quickly, especially when displayed in a variety of colors. At a price point of roughly $5 to $10 depending on your location and the materials used, they’re an accessible impulse buy for shoppers of all ages.

If you plan to sell items made from this pattern, please ensure the pattern you’re using permits commercial use. Creating your own written pattern based on your finished design is always a solid option.

For gifting, a small set of two or three octopus keychains tucked into a little organza bag or a small box makes a wonderful present. Pair them with a handwritten tag that says something like “I’m otterly glad you exist” and you’ll have a gift that people genuinely love.

Caring for Your Octopus Keychain

Since this will likely be attached to a set of keys or a bag, it’s going to see some wear. Here’s how to keep it looking its best.

For yarn made from acrylic, hand washing in cool water with a small amount of gentle soap is the safest approach. Reshape while damp and allow to air dry completely before using again.

Cotton yarn keychains can typically handle slightly more vigorous washing but should still be air dried to prevent shrinkage.

If the tentacles start to look a little limp over time, a light steam with an iron held a few inches away can help them perk back up.

Avoid putting the keychain in a dryer, as the heat can distort the shape of the head and cause the stuffing to clump unevenly.

Final Thoughts

There’s something genuinely magical about taking a small ball of yarn and a single hook and turning it into something as charming and personality-filled as a tiny crocheted octopus. This project is proof that crochet doesn’t have to be complicated to be wonderful. A few basic stitches, a little bit of stuffing, and some carefully placed safety eyes, and suddenly you have a creature with its own distinct character hanging from your keys.

Whether you’re making your very first amigurumi, looking for a satisfying quick project between larger works, or planning a batch for gifting, this easy octopus keychain delivers all the joy with very little time investment. So grab your hook, dig out some yarn from your stash, and give this little guy a try. There’s a very good chance you’ll end up making a whole pod of them.

Happy crocheting!
