Easy and Cute! Learn to Knit This Plush Octopus

There is something undeniably magical about turning a simple ball of yarn into something that makes people smile. And few knitting projects accomplish that quite as effectively as a plush stuffed octopus. With its round, squishy body and eight dangly legs, this little creature is the kind of project that beginners fall in love with and experienced knitters come back to again and again — whether they’re making them as gifts, nursery decorations, or just because the process is so satisfying.

If you’ve been looking for a beginner-friendly knitting project that’s actually exciting to finish, you’ve found it. This guide will walk you through everything you need to know to knit your very own plush octopus from start to finish. We’ll cover the materials, the basic stitches, the construction process, the stuffing and assembly, and all the little tips and tricks that will help you get a result you’re genuinely proud of. Even if you’ve only ever knitted a swatch or two, this project is within your reach. Let’s dive in.

Why Knit an Octopus?

Before we get to the needles and yarn, it’s worth talking about why this particular project has become so beloved in the knitting community. A few reasons stand out.

First, the shape of an octopus is remarkably forgiving. Because you’re working in the round and creating a soft, stuffed form, slight variations in tension or stitch count are hidden inside the finished object. Unlike a flat garment where every row shows on the surface, a plush toy can absorb small imperfections and still come out looking adorable.

Second, the octopus is made up of simple, repetitive shapes. The body is essentially a sphere or rounded dome shape. The tentacles are long tubes or i-cords. Neither of these requires complicated shaping, colorwork, or pattern reading beyond the basics. If you know how to knit in the round, increase, and decrease, you have everything you need.

Third, this project is genuinely quick. Depending on your pace and yarn weight, you can finish a plush octopus in a weekend. That kind of fast gratification is exactly what beginner knitters need to stay motivated and fall in love with the craft.

Finally — and most importantly — octopuses are just incredibly cute. The finished object is something you’ll want to keep, give away, and then immediately start making another one.

Materials You’ll Need

Gathering your materials before you start is always a good idea. Here’s what you’ll need for this project.

Yarn: A medium weight yarn (commonly labeled as worsted weight, or size 4) is the most beginner-friendly choice for this project. Look for something soft and slightly stretchy, since the body will be stuffed and you want it to feel good to the touch. A smooth yarn in your color of choice works beautifully. You’ll need approximately 100 to 150 yards for the body and tentacles of a palm-sized octopus. If you want a larger version, plan for 200 to 250 yards.

Acrylic yarn is a great choice here because it’s affordable, widely available, machine washable (great if you’re making this for a child), and comes in an enormous range of colors. You can also use cotton yarn for a slightly firmer texture, or a soft merino blend for something luxurious.

Needles: You’ll want double-pointed needles (DPNs) or a short circular needle in the size recommended on your yarn’s label, which for worsted weight is typically US size 7 or 8 (4.5mm to 5mm). If you prefer, you can also use a longer circular needle and work with the magic loop method. Any of these approaches will work.

Stuffing: Polyester fiberfill is the standard choice for stuffed toys. It’s inexpensive, widely available at craft stores, and gives your octopus that satisfying plushness. You can also use scraps of yarn as stuffing in a pinch, or even wool roving if you have it.

Safety eyes: These are plastic eyes with a post and a washer that lock in place from behind the knitted fabric. They give your octopus a charming, professional look. Common sizes for a small to medium octopus are 12mm or 15mm safety eyes. If you’re making this toy for a child under three years old, skip the safety eyes entirely and embroider the eyes with yarn instead, since safety eyes can be a choking hazard.

Tapestry needle: You’ll need this for weaving in your yarn ends and for seaming the tentacles to the body.

Stitch marker: Just one is usually enough to mark the beginning of your round.

Scissors: Any pair will do.

Basic Stitches You Need to Know

This pattern uses only a handful of techniques. If you’re brand new to knitting, take a little time to practice these before you start the actual project.

Cast on: The long-tail cast on is popular and creates a neat, even edge. For knitting in the round, you’ll cast your stitches onto double-pointed needles and join to work in a continuous circle. Just be careful not to twist your stitches when you join.

Knit stitch (K): The most fundamental stitch in knitting. When you work every stitch in the round using the knit stitch, you produce stockinette fabric, which naturally curls inward and creates a smooth, rounded surface — perfect for a stuffed toy body.

Knit two together (K2tog): A basic decrease that leans to the right and reduces your stitch count by one. You’ll use this to shape the top and bottom of the octopus body.

Make one (M1) or Knit front and back (KFB): Both of these are increases that add stitches and are used to expand the octopus body into its round shape. KFB is slightly simpler for beginners.

I-cord: This is the technique you’ll use for the tentacles. An i-cord is a small, narrow tube knitted on two or three stitches using double-pointed needles. It sounds tricky but is actually very rhythmic and meditative once you get going.

Knitting the Body

The body of your octopus begins at the top and grows wider as you add increases, then narrows again toward the opening at the bottom where the tentacles will attach.

Start by casting on 8 stitches. Divide them evenly across three or four double-pointed needles and join in the round, placing your stitch marker.

Round 1: Knit all stitches.

Round 2: KFB in every stitch. You now have 16 stitches.

Round 3: Knit all stitches.

Round 4: (K1, KFB) repeat to end of round. You now have 24 stitches.

Round 5: Knit all stitches.

Round 6: (K2, KFB) repeat to end of round. You now have 32 stitches.

Round 7: Knit all stitches.

Round 8: (K3, KFB) repeat to end of round. You now have 40 stitches.

Rounds 9 through 18: Knit every stitch in every round. This creates the straight sides of the body and gives it a nice, rounded dome shape once stuffed.

Now you’ll begin decreasing.

Round 19: (K3, K2tog) repeat to end of round. You now have 32 stitches.

Round 20: Knit all stitches.

Round 21: (K2, K2tog) repeat to end of round. You now have 24 stitches.

At this point, before your opening gets too small, insert your safety eyes between rounds 6 and 7, placing them approximately 6 to 8 stitches apart. Push the posts through the knitted fabric from the outside and attach the washers firmly on the inside.

Now is also the time to begin stuffing. Add fiberfill gradually, making sure to push it up into the top of the dome so the body feels firm and round, not flat or lumpy.

Round 22: Knit all stitches.

Round 23: (K1, K2tog) repeat to end of round. You now have 16 stitches.

Continue adding stuffing if needed, making sure the body is well-filled but not stretched or distorted.

Round 24: K2tog repeat to end of round. You now have 8 stitches.

Cut your yarn, leaving a 6-inch tail. Thread the tail through your tapestry needle and draw it through all 8 remaining stitches. Pull tight to close the opening and weave in the end securely on the inside.

Your body is done.

Knitting the Tentacles

This is where your octopus really starts to come to life. You’ll make eight tentacles, each one a simple i-cord worked on just 3 stitches.

To make an i-cord, cast on 3 stitches to one double-pointed needle. Knit all 3 stitches. Instead of turning your work as you would normally, slide the stitches back to the right end of the needle. Pull the yarn across the back of the stitches (this is the key step that creates the tube) and knit all 3 stitches again. Repeat this process — slide, pull yarn across back, knit — for every row.

Make each tentacle approximately 3.5 to 4 inches long for a small octopus, or 5 to 6 inches for a larger one. You can also make them different lengths to give your octopus a more playful, organic look — nature rarely makes everything identical, after all.

To finish each tentacle, cut the yarn leaving a few inches of tail, draw the tail through the 3 stitches, and pull to close. Leave a longer tail (about 8 to 10 inches) on each tentacle for attaching them to the body.

Make all 8 tentacles before moving on to assembly.

Assembly: Bringing Your Octopus Together

With your body complete and all 8 tentacles ready, it’s time to attach everything. This is also where you can add a little personality to your octopus by deciding how you want the tentacles positioned.

Thread the long tail of one tentacle onto your tapestry needle. Position the tentacle against the bottom of the octopus body and stitch it in place using small, secure stitches. Work the needle back and forth through the base of the tentacle and into the body fabric several times, then weave in the end on the inside of the body.

Repeat this for all 8 tentacles. A common arrangement is to evenly space the tentacles around the bottom edge of the body, creating a circle. You can also arrange them so they fan outward in a slightly irregular pattern, which makes the finished octopus look more dynamic and lively.

Once all the tentacles are attached, take a moment to fluff and shape your octopus. If the body feels a little flat, use your fingers to push the stuffing around from the outside until you get a round, satisfying shape.

Adding a Face and Extra Details

The eyes are already in place, but there are a few more things you can do to make your octopus look extra adorable.

If you’d like to add a little smile, you can use a small amount of yarn in a contrasting color and a tapestry needle to embroider a curved line just below and between the eyes. Keep the stitches small and consistent. A simple upward curve creates a happy face; a straighter line gives a more serene expression; a slight downward curve makes a thoughtful or grumpy octopus, which is charming in its own right.

Some knitters like to add a little blush to their octopus by using a chalk pastel or cosmetic blush powder applied lightly with a small brush to the cheek area on either side of the face. This gives the octopus a rosy, sweet look.

You can also experiment with making your octopus in two colors — one for the body and another for the tentacles — or in a gradient yarn that shifts color as you knit. The possibilities are as wide as your yarn stash.

Tips for Getting the Best Results

Even a simple project benefits from a few good habits and extra bits of knowledge, so here are some practical tips that will make the process smoother and the finished octopus more polished.

Maintain consistent tension throughout your knitting, especially in the tentacles. Because i-cord is worked with only a few stitches, uneven tension shows up more easily. Try to relax your hands and let the yarn flow smoothly.

Don’t skip the stuffing step at the right moment. Waiting until the body is almost completely closed makes it much harder to stuff properly. Add fiberfill as you go through the decrease rounds, a little at a time.

Weave in your ends carefully and securely. A stuffed toy gets handled and squeezed, so loose ends have a way of working themselves loose over time. Pass your tapestry needle through the yarn in several directions before trimming.

If your tentacles curl, that’s perfectly fine and actually part of their charm. The natural curl of i-cord looks like a little coil, which is very octopus-like. If you want them to hang straighter, block them gently by dampening the tentacles, shaping them, and letting them dry flat.

Label your yarn and keep a small note of which yarn and needle size you used, especially if you plan to make more of these. You’ll thank yourself later when someone asks for one and you can’t remember exactly what you did.

Making It Your Own

Once you’ve made your first octopus and gotten comfortable with the process, there’s a whole world of variations to explore. You can make a tiny octopus using fingering weight yarn on small needles for a miniature version that’s perfect as a keychain or ornament. You can make a giant octopus in super bulky yarn that becomes a pillow or a statement piece for a nursery. You can add stripes by switching colors every few rounds in the body. You can use novelty yarn — something sparkly or fuzzy — for a textured effect.

The octopus pattern is also a wonderful introduction to knitting toys in general. Once you understand how to build a round stuffed body by increasing and then decreasing, and how to make tubular attachments with i-cord, you can adapt those skills to make all sorts of creatures: jellyfish, caterpillars, starfish, little monsters with horns, and much more.

A Perfect Gift for Any Occasion

One of the most wonderful things about this project is how universally appealing the finished object is. A plush knitted octopus makes a beautiful baby shower gift (especially if you use soft, washable yarn), a thoughtful birthday present for a child, a cheerful desk companion for a friend who needs a little pick-me-up, or even a decorative element in a coastal or nautical themed room. They’re quick enough to make in multiples, which means once you’ve got the hang of it, you can batch-produce a little school of octopuses in different colors and sizes.

Because they’re knitted and stuffed by hand, each one carries that particular warmth that handmade gifts have — the sense that someone sat down, picked up their needles, and thought about the recipient while they worked. That’s not something you can buy in a store, and it’s not something that ever goes out of style.

You’ve Got This

Knitting a plush octopus is one of those projects where the effort involved and the delight of the finished product are perfectly balanced. It’s accessible enough that a new knitter can finish one in their first or second week of picking up needles. It’s satisfying enough that an experienced knitter will enjoy the meditative repetition of those tentacles. And the result — a round, squishy, wide-eyed little creature with eight wobbly legs — is almost guaranteed to make whoever receives it break into a smile.

So wind up your yarn, set out your needles, find a good podcast or playlist to listen to, and start casting on. Your plush knitted octopus is waiting to come into the world, and it’s going to be absolutely adorable.
