Easy and Cute! Learn to Knit This Plush Octopus

There is something deeply satisfying about finishing a knitting project that looks adorable, makes a wonderful gift, and teaches you real techniques along the way. This plush octopus checks every single one of those boxes. Whether you are picking up needles for the first time or you have been knitting for a few years and want a fun weekend project, this little eight-armed creature is exactly the kind of pattern that keeps you motivated from cast-on to the final sewn-in tail of yarn.

Octopus stuffed animals have become increasingly popular as handmade gifts, baby shower presents, and even comfort items for both children and adults. Knitting your own means you get to choose the colors, customize the size, and pour a little love into every stitch. By the end of this tutorial, you will have a complete understanding of how to knit a plush octopus from the body all the way down to those wiggly tentacles, and you will have picked up several useful knitting skills along the way.

Let us get started.

Why Knit an Octopus?

Before we dive into the pattern itself, it is worth taking a moment to appreciate why this particular project has become such a beloved choice among knitters of all skill levels.

First, the shape is forgiving. Unlike a sweater where every row needs to match up perfectly with your gauge swatch, a stuffed animal has a lot of natural flexibility. Slight variations in tension actually give the finished toy more character and a handmade charm that machine-made versions simply cannot replicate.

Second, the octopus shape is deceptively simple. The body is essentially a large round dome that you knit in the round, stuff firmly, and then close up. The tentacles are long, thin tubes or flat strips that hang down and give the toy its signature look. Once you understand those two basic components, you have the whole project mapped out in your mind.

Third, it is a fantastic stitch practice project. You will use increases and decreases for shaping the body, basic knitting in the round, and either i-cord or flat knitting for the tentacles. These are foundational skills that transfer directly to other patterns including hats, socks, and amigurumi-style toys.

And of course, the finished object is irresistibly cute. A squishy, colorful octopus with little button eyes sitting on a bookshelf or tucked into a gift bag has a way of making everyone smile.

Materials You Will Need

Getting your supplies together before you start knitting saves a lot of frustration. Here is everything you need for this project.

Yarn: Choose a medium weight yarn in your main color. This is roughly equivalent to a worsted weight or an Aran weight, labeled as a size 4 on the yarn band. Approximately 150 to 200 yards will be plenty for the body and all eight tentacles. You can also grab a small amount of a contrasting color if you want to add stripes or color-blocked tentacles.

Soft acrylic yarn works particularly well for stuffed toys because it is machine washable, holds its shape well after stuffing, and comes in an enormous range of colors. That said, if you prefer natural fibers, a soft merino or cotton blend is lovely and safe for babies.

Needles: You will need double-pointed needles or a short circular needle in a size that creates a fairly tight fabric. A US size 6 or 7 (4mm to 4.5mm) needle works well with most worsted weight yarns. The goal is to knit tightly enough that the stuffing does not peek through the stitches.

Stuffing: Polyester fiberfill is the go-to choice. It is affordable, washable, hypoallergenic, and gives the body a wonderfully round, plush shape. Use enough to make the body feel firm but not stretched.

Eyes: Safety eyes in 12mm or 15mm diameter give the octopus a classic stuffed-animal look. If you are making this toy for a child under three, embroider the eyes instead using black yarn or felt, since safety eyes can come loose and pose a choking hazard.

Additional tools: A yarn needle for seaming and weaving in ends, scissors, stitch markers, and a small amount of craft wire (optional, if you want the tentacles to be poseable).

Understanding the Basic Techniques

If you are new to knitting in the round or to toy knitting in general, a quick overview of the key techniques will make the pattern much easier to follow.

Knitting in the round simply means joining your stitches into a circle and knitting continuously without turning your work. This creates a seamless tube of fabric, which is perfect for the rounded body of the octopus. You can use double-pointed needles (usually sold in sets of four or five) or a short circular needle for this.

Magic loop is a method of using a long circular needle to knit small circumferences in the round. Some knitters prefer it to double-pointed needles because you only have to manage one needle instead of several. Either method works perfectly for this project.

Increases make your piece wider by adding stitches to a row. The most common increase you will use here is the knit front and back (kfb), where you knit into the front of a stitch and then again into the back before slipping it off the needle. This adds one stitch for each increase made.

Decreases make your piece narrower by combining stitches. You will use k2tog, which means knitting two stitches together as if they were one. This is the decrease used to close the top and bottom of the octopus body.

I-cord is a technique for making a narrow, round tube of knitting on double-pointed needles. You cast on a small number of stitches, knit across, and then slide the stitches back to the opposite end of the needle without turning your work. You always knit from the right side, which causes the yarn to pull across the back and form a neat little tube. I-cord tentacles look polished and round, and they drape beautifully.

Knitting the Octopus Body

Now it is time to actually start knitting. The body is worked from the top down, beginning with a small number of stitches and increasing out to the widest point before decreasing back in toward the bottom.

Cast on: Using your preferred method for knitting in the round, cast on 8 stitches. Distribute them evenly across your double-pointed needles or set up your magic loop, place a stitch marker, and join to work in the round, being careful not to twist your stitches.

Round 1: Knit all stitches.

Round 2 (increase round): Kfb in every stitch. You now have 16 stitches.

Round 3: Knit all stitches.

Round 4 (increase round): Kfb in every stitch. You now have 32 stitches.

Round 5: Knit all stitches.

Round 6 (increase round): Kfb in every other stitch (k1, kfb, repeat to end). You now have 48 stitches.

Rounds 7 through 10: Knit all stitches with no increases.

Round 11 (increase round): Kfb in every 6th stitch (k5, kfb, repeat to end). You now have 56 stitches.

Rounds 12 through 20: Knit all stitches. This section creates the full, rounded belly of the octopus.

At this point, if you want to add eyes, do it now before you close the body up. Attach safety eyes approximately 8 to 10 rounds up from your cast-on edge, spacing them about 8 stitches apart on the front of the body. If embroidering, do this at the finishing stage.

Round 21 (decrease round): K2tog in every 7th stitch (k6, k2tog, repeat to end). You now have 49 stitches.

Round 22: Knit all stitches.

Round 23 (decrease round): K2tog in every 6th stitch. You now have 42 stitches.

Round 24: Knit all stitches.

Continue decreasing in this fashion, reducing your stitch count by approximately 7 stitches every other round, until you have about 16 stitches remaining. Begin stuffing the body firmly with polyester fiberfill before the opening becomes too small to work with comfortably. Keep adding stuffing as the gap closes to ensure the final shape is fully round and firm.

Once you have about 8 stitches remaining, cut your yarn leaving a 10-inch tail. Thread the tail onto a yarn needle and draw it through the remaining live stitches. Pull tight to close the opening completely, then pull the yarn to the inside of the body and weave in the end securely.

Knitting the Tentacles

Now comes the fun part. You will knit eight tentacles, each one a long i-cord that you will attach evenly around the bottom of the body.

For each tentacle:

Using double-pointed needles, cast on 4 stitches. Do not join in the round. Instead, knit across the 4 stitches, then slide them to the opposite end of the needle without turning your work. Pull the yarn firmly from behind and knit across again. Repeat this process, and you will see a small, neat tube forming.

Continue working i-cord until the tentacle measures approximately 5 to 7 inches long, depending on how long you want the arms to be. For a classic look, making all eight the same length gives the octopus a symmetrical, tidy appearance. For a more playful, organic look, vary the lengths slightly.

To finish each tentacle, cut the yarn leaving a 6-inch tail. Thread it through the remaining 4 stitches, pull tight, and weave in the end. If you want curling tentacles, lightly steam-block each one or wet them and coil them around a pencil, letting them dry in that shape.

Alternatively, you can knit flat strips for the tentacles if i-cord is new to you. Cast on 4 stitches and work in stockinette stitch (knit one row, purl one row) until the strip reaches your desired length. The edges will naturally curl inward as stockinette tends to do, creating a rounded shape that looks similar to i-cord with slightly less effort.

Attaching the Tentacles

With all eight tentacles finished, it is time to attach them to the body. This step is where your octopus really comes to life.

Using a yarn needle and a length of your main color yarn, sew each tentacle to the bottom edge of the body, spacing them evenly around the circumference. Think of the bottom of the body like a clock face, and place your tentacles at the 12, 1:30, 3, 4:30, 6, 7:30, 9, and 10:30 positions. This gives you eight evenly spaced arms with a natural, symmetrical spread.

Make sure to sew each tentacle on securely, especially if the toy is intended for a child. Pass the needle through the base of the tentacle and the body fabric several times before fastening off, and check that each tentacle feels firmly attached before finishing the seam.

Adding the Face and Final Details

The face of your octopus is where personality really shines through. With just a few simple additions, you can make your octopus look happy, sleepy, surprised, or mischievous.

If you have already installed safety eyes, add a simple smile using black embroidery thread or a length of dark yarn. A small curved stitch just below and between the eyes does the trick perfectly.

You can also embroider tiny dots for nostrils or small circular cheek markings using a contrasting color of yarn. Pink or rosy blush cheeks are a particularly popular touch that gives stuffed animals a soft, childlike charm.

If you want to get more creative, try adding texture to the underside of the tentacles with small embroidered circles to represent suckers. A few French knots or small chain-stitch circles in a lighter color give a lovely, detailed finish without requiring any advanced embroidery skill.

Color Ideas and Variations

One of the best things about knitting your own toys is the complete creative freedom you have with color. Here are some inspiring combinations to consider.

A deep ocean teal with cream-colored tentacles is stunning and looks beautifully nautical. Bright coral pink is sweet and cheerful, especially with a lavender face. A rainbow octopus worked in self-striping yarn is endlessly cheerful and requires no color changes on your part since the yarn does all the work automatically. For Halloween, a deep purple or black body with orange tentacles is irresistibly festive.

You can also experiment with size. Using a chunky weight yarn and larger needles produces an oversized, pillow-like octopus that makes an excellent cuddle companion. Using fingering weight yarn and tiny needles creates a miniature version that fits in the palm of your hand and makes a charming ornament or keychain.

Finishing Touches and Blocking

Weave in all remaining yarn ends carefully and trim them close to the fabric. Take a moment to fluff and shape your octopus, adjusting the stuffing from the outside by gently squeezing and rounding the body with your hands.

Blocking is generally not necessary for stuffed toys, but if your tentacles look a little uneven or the fabric has some uneven tension, a light steam from a garment steamer or iron held several inches above the surface can help smooth things out without flattening the stuffing.

If you used acrylic yarn, be very careful with heat as high temperatures can damage the fibers. A quick spritz of water and gentle reshaping by hand is usually all you need.

Gifting and Caring for Your Knitted Octopus

A handmade knitted toy is one of the most thoughtful gifts you can give. To make the presentation extra special, tuck the octopus into a small fabric bag or tie it up with a ribbon in a complementary color. Including a small card with care instructions is also a lovely touch.

For washing, if you used machine-washable yarn, the octopus can go into a mesh laundry bag on a gentle cycle with cold water. Air dry it flat or hang it by one tentacle and it will hold its shape beautifully. If you used natural fibers like wool, hand wash gently in cool water and lay flat to dry.

Tips for Beginners

If this is one of your first knitting projects, here are a few pieces of advice that will make the whole experience smoother and more enjoyable.

Tension matters, but it does not need to be perfect. Stuffed toys are forgiving, so if your first few rounds look a little loose or uneven, keep going. Your tension usually evens out as you warm up.

Do not skip the stitch markers. Placing a marker at the beginning of each round helps you keep track of where you are in the pattern and makes it much easier to count your increases and decreases accurately.

Stuff the body gradually as you decrease. Trying to stuff it all at once at the very end makes it difficult to get a firm, even shape. Adding stuffing in stages gives you much more control over the final result.

Watch video tutorials if a technique is new to you. Written instructions for things like magic loop or i-cord can be hard to picture from text alone, but watching someone’s hands do the movement for even thirty seconds makes everything click.

And finally, enjoy the process. Knitting a plush toy is genuinely fun, and the moment you attach that last tentacle and hold up the finished octopus is one of the most satisfying feelings in all of crafting.

Your New Favorite Pattern

The knitted plush octopus is the kind of pattern you will come back to again and again. It is fast enough to finish over a weekend, flexible enough to customize endlessly, and appealing enough that everyone who sees it immediately wants one. Once you have made your first, you will likely find yourself knitting a second in a different color before the week is out.

Whether you hang it from a rearview mirror, add it to a baby’s toy basket, place it on a shelf as a fiber art display, or ship it off to a friend who needs a little extra cheer, this tiny eight-armed marvel carries a lot of warmth for such a small project. So cast on, enjoy the rhythm of the stitches, and welcome your plush octopus into the world.
