In this post, you will find everything you need to make your own adorable mini octopus keychain, including a full materials list, stitch abbreviations, gauge information, detailed written instructions, tips for stuffing and finishing, and ideas for customizing your little sea creature in dozens of different ways. Grab your hook and a scrap of yarn, because we are diving in.

Why You Will Love This Mini Octopus Keychain Pattern

Before we get into the how-to, let’s talk about why this project has become such a popular choice among crocheters of all skill levels.

First, it uses very little yarn. This is the perfect pattern for using up those tiny balls of leftover yarn that are too small for a bigger project but too pretty to throw away. A single skein of worsted weight yarn can produce dozens of these little guys, which also makes them a fantastic choice for selling at craft fairs or giving as handmade gifts.

Second, it works up quickly. Once you get the hang of the construction, you can finish one mini octopus keychain in under an hour. That makes it a perfect project to take on a road trip, work on during a lunch break, or finish while watching a movie.

Third, the steps are genuinely easy. The entire body is crocheted in the round using single crochet stitches, and the tentacles are made with simple slip stitch or chain loops. There are no complicated stitch combinations or colorwork techniques required, although we will share some ideas for adding those elements if you want to level up your design.

Finally, these little octopuses are just endlessly charming. They make great bag charms, zipper pulls, stocking stuffers, baby shower gifts, and friendship tokens. Once you make one, you will probably want to make ten more.

Materials You Will Need

You do not need much to get started. Here is a complete list of what to gather before you begin:

Yarn: A small amount of worsted weight yarn (Category 4) in your main color. Fingering or DK weight also works beautifully if you adjust your hook size accordingly. You will need less than 20 yards for the body and tentacles combined, so this is an ideal scrap yarn project.

Crochet Hook: Size 3.5mm (E hook) for fingering or DK weight, or size 4.0mm to 5.0mm (G or H hook) for worsted weight. Use whatever hook gives you a firm, tight fabric so the stuffing does not show through.

Stuffing: A small amount of polyfill stuffing or a cotton ball. You only need enough to lightly fill the head so it holds its rounded shape.

Safety Eyes: Two 6mm or 8mm black safety eyes. If you are making this for a child under three years old, embroider the eyes instead using black yarn or thread for safety.

Yarn Needle: For weaving in ends and closing the head.

Scissors: Small scissors work fine.

Keychain Ring and Split Ring: A metal keychain ring to attach your octopus when it is finished. You can find these at any craft store, dollar store, or online in bulk packs.

Stitch Marker: Optional but helpful for tracking your rounds.

Gauge

Gauge is not critical for this project since it is a decorative item rather than a garment that needs to fit. However, as a general guide, you are aiming for a tightly crocheted fabric so that the stuffing stays hidden inside. If you can see large gaps between your stitches, try going down a hook size.

With worsted weight yarn and a 4.5mm hook, the finished octopus head should measure approximately 1.5 to 2 inches in diameter. The total length including tentacles is typically around 3 to 4 inches.

Stitch Abbreviations

This pattern is written in US crochet terminology. Here are the abbreviations used throughout:

ch — chain

sl st — slip stitch

sc — single crochet

inc — increase (2 single crochets worked into the same stitch)

dec — invisible decrease (insert hook into front loops of next two stitches, yarn over and pull through both loops, yarn over and pull through remaining two loops)

MR — magic ring

BLO — back loops only

st — stitch

sts — stitches

rnd — round

Mini Octopus Keychain Free Crochet Pattern

Now let’s get into the actual pattern. The construction happens in two parts: the head (which includes the body), and the tentacles. Everything is worked in continuous rounds unless otherwise noted.

Part One: The Head

Round 1: Make a magic ring. Work 6 sc into the ring. Pull the ring closed. (6 sts)

Round 2: Inc in each st around. (12 sts)

Round 3: Sc 1, inc — repeat from to around. (18 sts)

Round 4: Sc 2, inc — repeat from to around. (24 sts)

Round 5: Sc 3, inc — repeat from to around. (30 sts)

Rounds 6 through 9: Sc in each st around, working 4 rounds even with no increases or decreases. (30 sts per round)

Now is the time to insert your safety eyes. Place them between rounds 6 and 7, spacing them about 6 to 8 stitches apart. Secure the washers on the inside. If you are embroidering eyes instead, you can do that after the head is fully closed.

Round 10: Sc 3, dec — repeat from to around. (24 sts)

Round 11: Sc 2, dec — repeat from to around. (18 sts)

Begin stuffing the head lightly at this point. Do not overstuff — you want the head to be gently rounded, not hard and lumpy. A small pinch of polyfill is usually enough.

Round 12: Sc 1, dec — repeat from to around. (12 sts)

Round 13: Dec around. (6 sts)

Fasten off, leaving a short tail. Use your yarn needle to close the remaining hole by running the tail through the front loops of each of the 6 remaining stitches. Pull tight and secure. Weave in the end.

Part Two: The Tentacles

The tentacles are made directly on the bottom of the head. You will be working into the stitches of the last full round before you began the decreases, which is the round of 30 stitches. However, since we decreased the body down, you can also create the tentacles by working into the stitches along the bottom edge of the finished head. Both methods work well.

Many crocheters find it easiest to create a small flat base before adding tentacles. Here is the method that gives the cleanest result:

Setting up the tentacles:

After closing the head, join your yarn at any point along the bottom of the head. You can use the same color or switch to a contrasting color for the tentacles — this is entirely up to you and makes a fun design variation.

Work a base ring of 24 stitches around the bottom opening of the head. If your head still has an open bottom edge from the decreases, work directly into those stitches. If it was closed fully, lightly open the bottom and work into the edge.

Creating 8 tentacles:

The standard octopus has 8 tentacles. Divide your 24 base stitches into 8 groups of 3 stitches each.

For each tentacle, work as follows:

Chain 12. Starting in the second chain from the hook, sl st in each chain back to the base — that is 11 slip stitches. Sl st into the next 3 base stitches to anchor the tentacle and advance to the starting position of the next tentacle.

Repeat this sequence 8 times total until all 8 tentacles are complete.

Fasten off and weave in all ends carefully so none of them peek out between tentacles.

Alternate Tentacle Method (Curly Tentacles)

If you want tentacles that naturally curl and look even more playful and dimensional, try this method instead:

For each tentacle, chain 15. Starting in the second chain from the hook, work 2 sl sts into each chain all the way back to the base. The extra stitches force the tentacle to spiral and curl. Attach each one to the base just as described above.

The curly tentacle method produces a slightly more elaborate look and is especially beautiful in a variegated or self-striping yarn where each tentacle picks up a slightly different color.

Attaching the Keychain Ring

Once your octopus is fully assembled and all ends are woven in, it is time to add the keychain hardware.

Cut a short length of yarn or use a small piece of jewelry wire or a split ring to attach the metal keychain ring to the top of the octopus head. The cleanest method is to thread a doubled piece of yarn through the top of the head, loop it through the keychain ring, and tie it off securely with several knots before weaving the ends back into the head.

Alternatively, you can crochet a small loop at the top of the head during construction. When you finish round 1, chain 5, then sl st back into your starting stitch to create a hanging loop before continuing with round 2. This built-in loop is secure and looks very tidy.

Tips for the Best Results

Getting a great-looking mini octopus keychain is all about a few small details. Here are the most helpful tips to keep in mind:

Keep your tension firm. A loose, airy fabric will let your stuffing show through and make the head look lumpy. If you tend to crochet loosely, go down a hook size or use a fingering weight yarn with your usual worsted hook.

Do not overstuff. This is one of the most common mistakes with small amigurumi projects. Too much stuffing stretches the fabric and pushes stitches apart. Use just enough polyfill to give the head a soft, rounded shape.

Place your safety eyes before closing the head. It is nearly impossible to add safety eyes after the opening is too small. If you forget, you will need to embroider eyes from the outside instead.

Use the invisible decrease for cleaner shaping. The standard decrease can leave a small bump or hole in the fabric. The invisible decrease (worked through the front loops only) gives a much smoother result.

Weave in ends securely. Because keychains get a lot of daily handling and movement, weave your ends in multiple directions and through several stitches to make sure they never work loose over time.

Block if needed. A light steam or wet blocking can smooth out any uneven stitches and help the tentacles lay nicely.

Fun Ways to Customize Your Mini Octopus Keychain

One of the best things about this pattern is how much personality you can inject into each octopus just by changing a few simple elements.

Color combinations are the most obvious place to start. Try pastel colors for a dreamy, cottagecore aesthetic. Use deep jewel tones like teal, plum, and gold for a more sophisticated look. Try neon colors for a bold, modern vibe. Self-striping or variegated yarn creates an automatically beautiful, multicolored octopus without any colorwork required.

Different yarn textures completely transform the finished look. Chenille yarn produces a velvety, plush octopus that is irresistibly soft. Sparkle or metallic yarn gives a festive, glittery effect. Cotton yarn creates a cleaner, slightly stiffer result that holds its shape especially well.

Embroidered details can add tons of personality. Add small embroidered cheeks using pink yarn and a yarn needle. Stitch on a tiny smile. Add freckles or spots. Embroider a little bow or crown on top of the head. All of these small touches make each octopus feel truly unique and handmade.

Size variations are easy to achieve by changing your yarn weight. Use fingering weight yarn and a 2.5mm hook for a truly tiny, miniature octopus that fits on a charm bracelet. Use bulky yarn and a 6mm hook for a larger, chunkier version that works as a bag charm or backpack pendant. The pattern steps remain exactly the same — only the scale changes.

Seasonal color palettes make these perfect gifts all year long. Orange and black for Halloween, red and white for Christmas, soft yellow and green for spring, or patriotic red, white, and blue for summer holidays. Make a set in school colors. Match someone’s favorite sports team. The possibilities really are endless.

Ideas for Gifting and Selling

Because this project is so quick and uses such small amounts of materials, it is a wonderful choice for handmade gifts and craft fair inventory. A set of three or four mini octopus keychains in complementary colors makes a beautiful packaged gift. Add a small card with the recipient’s name and a little note about how the octopus was made by hand, and you have something truly special.

For selling, these small amigurumi keychains are consistently popular at markets and online shops. They photograph beautifully, ship at minimal cost, and have a wide appeal that cuts across age groups. Children love them, teens love them, adults love them. They work as stocking stuffers, birthday gifts, party favors, and everyday accessories.

If you plan to sell items made from this pattern, please check the terms of the pattern you are using to make sure commercial sales are permitted. This free pattern is offered for personal and small-scale commercial use with credit appreciated.

Frequently Asked Questions

Can a beginner make this pattern?

Yes, absolutely. If you know how to make a magic ring, single crochet, increase, and decrease, you have all the skills you need. The construction is entirely in the round with no seaming required.

How long does it take to make one?

Most crocheters can finish one mini octopus keychain in 30 to 60 minutes once they are familiar with the pattern. The first one might take a little longer while you get comfortable with the tentacle construction.

Can I make this without a magic ring?

Yes. If you prefer, chain 2 and work 6 single crochets into the second chain from the hook as an alternative starting point. The magic ring gives a tighter, neater center, but both methods work.

What if I don’t have safety eyes?

You can embroider eyes using black yarn or thread. Use a straight stitch or small satin stitch to create a circular or oval eye shape. Embroidered eyes are actually the safer choice for any item intended for young children.

Can I make this octopus without stuffing?

Yes, though the head will be flat rather than rounded. Some people prefer an unstuffed version for a flatter, more medallion-like keychain. You can also insert a small piece of wire inside the tentacles before crocheting them to make them poseable, which is a fun design variation.
