Knit Octopus: Free Knitting Pattern for a Cuddly Eight-Armed Friend

There is something undeniably charming about an octopus. Maybe it is the way those eight arms tumble in every direction, or maybe it is the wide-eyed, slightly bewildered expression that most knitted versions end up wearing. Whatever the reason, the knitted octopus has become one of the most beloved toy-knitting projects in the fiber arts community, and once you make one, you will completely understand why. They are addictive to knit, wildly satisfying to stuff, and they make the most wonderful gifts for babies, toddlers, and anyone who has a soft spot for creatures of the deep.

This free knitting pattern will walk you through every step of creating your own knitted octopus from start to finish. Whether you are a beginner looking for a project that teaches you in the round knitting, or an experienced knitter who wants a quick and rewarding make, this pattern has something for you. By the end, you will have a squishy, huggable octopus that looks absolutely adorable sitting on a shelf or tucked under a child’s arm.

Let us dive in.

What You Will Need

Before you cast on a single stitch, gather your materials. Having everything at hand makes the knitting process smooth and enjoyable, and you will not have to stop mid-project hunting for your yarn needle or a specific size of needle.

Yarn: The best yarn for a knitted octopus toy is a smooth, medium-weight worsted yarn (approximately 200 yards). Choose something machine washable if this toy is intended for a baby or young child, since toys get dirty fast and a yarn that can go in the washing machine is a lifesaver for parents. Acrylic blends work wonderfully here because they are durable, soft, and come in every color imaginable. A classic octopus might be done in a deep teal, purple, or coral, but there is absolutely no rule stopping you from knitting a neon yellow or a dusty rose octopus. This is your creation entirely.

Needles: US size 7 (4.5mm) double-pointed needles (DPNs) or a 16-inch circular needle, depending on your preferred method of knitting in the round. If you are comfortable with the magic loop technique, a longer circular needle works just as well.

Notions: You will need a set of stitch markers, a yarn needle for seaming and weaving in ends, scissors, polyester fiberfill stuffing, safety eyes (12mm work beautifully for a medium-sized octopus, though you can embroider eyes instead if the toy is for a baby under three years old), and a row counter or notepad to track your rounds.

Gauge: Approximately 20 stitches and 28 rows = 4 inches in stockinette stitch. Gauge matters less here than it does in a garment pattern, but keeping an even tension will ensure your stuffing does not show through the fabric.

Sizing and Finished Measurements

This pattern creates a finished octopus approximately 8 inches tall (including tentacles) and about 5 inches wide at the widest point of the head. The tentacles hang approximately 4 to 5 inches below the body. You can easily scale the size up or down by adjusting your yarn weight and needle size. A chunky yarn on larger needles will give you a big, squishy octopus that makes a wonderful floor cushion for small children. A fingering weight yarn on tiny needles creates a miniature octopus that is almost too cute to be real.

Pattern Notes

This octopus is knitted in two main sections: the body (which includes the head) and the eight tentacles. The tentacles are knitted separately as i-cord tubes and then attached to the base of the body. This method is beginner-friendly because each piece is small and quick to knit, and it gives you a nice break from the main body while still keeping the project moving at a satisfying pace.

All rounds are worked in stockinette stitch (knit every round when working in the round) unless otherwise specified. Decreases are worked as k2tog (knit two together) for right-leaning decreases and ssk (slip, slip, knit) for left-leaning decreases. Increases are worked as kfb (knit into the front and back of a stitch).

A note on safety eyes: if this octopus is intended for a child under three years old, do not use plastic safety eyes. Instead, embroider the eyes using black yarn or embroidery floss. You can create a simple round eye with a few stitches of satin stitch, or use French knots for a smaller, more delicate look.

The Pattern

Part One: The Body

Cast On

Using your preferred method for casting on in the round, cast on 10 stitches and join to work in the round, being careful not to twist. Place a stitch marker to mark the beginning of the round.

Rounds 1–2: Knit all stitches.

Round 3 (Increase Round): Kfb in every stitch. You now have 20 stitches.

Rounds 4–5: Knit all stitches.

Round 6 (Increase Round): Kfb, k1; repeat from to end of round. You now have 30 stitches.

Rounds 7–8: Knit all stitches.

Round 9 (Increase Round): Kfb, k2; repeat from to end of round. You now have 40 stitches.

Rounds 10–11: Knit all stitches.

Round 12 (Increase Round): Kfb, k3; repeat from to end of round. You now have 50 stitches.

Rounds 13–22: Knit all stitches for 10 rounds. This creates the rounded dome of the octopus head.

Round 23 (Decrease Round): K2tog, k3; repeat from to end of round. You now have 40 stitches.

This is the point at which you will insert your safety eyes, if you are using them. Place them on the front of the head, approximately between rounds 15 and 18, spaced about 10 to 12 stitches apart. The eyes should sit on the widest part of the dome, giving your octopus that endearing, curious expression.

Round 24: Knit all stitches.

Round 25 (Decrease Round): K2tog, k2; repeat from to end of round. You now have 30 stitches.

Round 26: Knit all stitches.

At this point, begin stuffing the head firmly with polyester fiberfill. You want a good amount of stuffing so the head holds its round shape and feels satisfyingly plump when squeezed. Do not wait until the opening is too small to get your stuffing in evenly.

Round 27 (Decrease Round): K2tog, k1; repeat from to end of round. You now have 20 stitches.

Round 28: Knit all stitches.

Round 29 (Decrease Round): K2tog across all stitches. You now have 10 stitches.

Add any final stuffing you need to fill out the shape, then cut your yarn leaving a 10-inch tail. Using a yarn needle, thread the tail through the remaining 10 stitches and pull tight to close the opening. Weave in the end securely on the inside.

Part Two: The Tentacles (Make 8)

Each tentacle is knitted as a simple i-cord that begins wide and tapers to a point. I-cord is worked on double-pointed needles: you cast on your stitches, knit across, and instead of turning your work, you slide the stitches to the other end of the needle and knit again, pulling the working yarn across the back. After a few rounds, a tidy, seamless tube of knitting forms as if by magic.

Cast On

Cast on 8 stitches onto one double-pointed needle.

Rounds 1–5: Work i-cord for 5 rounds.

Round 6 (Decrease): Ssk, k4, k2tog. You now have 6 stitches.

Rounds 7–11: Work i-cord for 5 rounds.

Round 12 (Decrease): Ssk, k2, k2tog. You now have 4 stitches.

Rounds 13–18: Work i-cord for 6 rounds.

Round 19 (Decrease): Ssk, k2tog. You now have 2 stitches.

Round 20: K2tog. You now have 1 stitch.

Cut yarn, pull through remaining stitch to fasten off. Your tentacle will be slightly curved and tapered, which gives it a lovely organic look. Make eight of these little tentacles. You can make them all in the same color as your body, or you can switch things up and knit them in a contrasting or complementary color for a playful two-tone octopus.

Part Three: Assembling Your Octopus

Assembly is where everything comes together and your octopus truly comes to life. This step requires a bit of patience and a good sharp yarn needle, but it is genuinely fun to watch the pieces combine into the finished creature.

Lay your body upside down so you are looking at the flat bottom opening. Arrange your eight tentacles around the base in a rough circle, evenly spaced. You may want to pin them in place before sewing to ensure the spacing looks right.

Using your yarn needle and a length of yarn (use the same color as your body for invisible seaming, or a contrasting color if you want a decorative effect), sew each tentacle firmly to the base of the body. Work through both the body fabric and the cast-on edge of the tentacle, going around the attachment point a few times to make sure it is secure. Tug the tentacle gently to test the attachment before moving on to the next one.

Once all eight tentacles are attached, weave in any remaining ends and give your octopus a good look from every angle. Adjust any tentacles that seem uneven and smooth out the stuffing inside the head by massaging the body gently.

Finishing Touches and Customization Ideas

The basic pattern gives you a wonderful, classic knitted octopus, but there is so much room to personalize this little creature.

Blush cheeks: Using pink yarn or embroidery floss, work a few small stitches or a loose French knot on each side of the face, just below the eyes, to give your octopus rosy cheeks. It instantly makes the expression look sweeter and more bashful.

A little bow: Tie a small bow from a scrap of ribbon and tack it between two of the tentacles at the front. This reads as instantly adorable and makes a particularly sweet gift.

Curled tentacles: After blocking your finished octopus, you can encourage the tentacles to curl by dampening them and wrapping them around a pencil, then letting them dry completely. This gives a more whimsical, animated look.

Stripes: If you want a striped octopus, simply carry two colors of yarn and switch every two rounds in the body section. Carry the unused yarn loosely up the inside of the work so you do not have to weave in a dozen ends.

Color gradients: Using a gradient or self-striping yarn makes each octopus completely unique without any extra effort on your part. The body begins at one end of the color repeat and travels through the spectrum as you knit, producing a result that looks far more complicated than it actually is.

Tips for Knitting Your First Octopus

If this is your first toy-knitting project, here are a few pieces of advice that will make the process smoother and the result more polished.

Tension is everything with toys. Because toy fabric is stuffed firmly, any uneven stitches or holes in the fabric will show through, especially if your stuffing is white or light-colored. Try to maintain an even tension throughout, and if you are getting holes at your increase points, try working your increases as lifted increases rather than kfb.

Do not understuff. A toy that is understuffed will be floppy and will not hold its shape. Be generous with your polyester fiberfill, packing it in firmly as you go. The finished toy should feel pleasantly dense and hold its shape when you set it down.

Weave in your ends carefully. The last thing you want is for a yarn end to work its way loose inside a toy and create a tangled mess in the stuffing. Weave each end in several different directions and pull it taut before trimming.

Block your finished octopus by dampening it lightly and shaping it with your hands, then letting it dry flat. This evens out any uneven tension and gives the finished piece a much more professional appearance.

The Perfect Gift for Any Occasion

One of the greatest things about a knitted octopus is its versatility as a gift. Baby shower gifts in soft, gender-neutral colors like mint, cream, or lavender are always a hit. A bright rainbow octopus makes an inspired birthday gift for a toddler or preschooler. Teal and purple octopuses look wonderful displayed on a bookshelf in a teenager or adult’s room. Deep navy or forest green with gold accents creates something that feels almost sophisticated, the kind of thing a knitter would be proud to keep for themselves.

If you are making this as a gift for a newborn, remember to skip the safety eyes and embroider them instead, and make sure all yarn ends are woven in extremely securely. Wash the finished toy on a gentle cycle in a mesh laundry bag before gifting, both to test its durability and to ensure it is clean and soft.

Storing and Caring for Your Knitted Octopus

If you used a machine-washable yarn (and this pattern strongly recommends it for toys), caring for your knitted octopus is simple. Turn it inside out if possible, or tuck it into a mesh laundry bag, and wash on a gentle cycle with cold water. Reshape while damp and air dry completely before use. Putting it in the dryer can felt wool yarns and misshape the stuffing, so air drying is always the safer choice.

If you used a non-superwash wool or other animal fiber, hand washing is the way to go. Fill a basin with cool water and a small amount of wool wash, submerge the octopus, and squeeze gently. Do not wring or agitate, as this can cause felting. Roll it in a towel to remove excess water, then reshape and air dry.

Why Knitters Love This Pattern

The knitted octopus sits at a sweet intersection of accessibility and reward. It is small enough to finish in a weekend but interesting enough to hold your attention. The eight tentacles give you a chance to practice i-cord, which is one of those techniques that feels clunky the first time and then becomes second nature by the time you have worked all eight. The body teaches seamless increases and decreases in the round, which are skills that will serve you well in everything from hats to sweaters.

Beyond the technical benefits, there is something deeply satisfying about making a toy by hand. A knitted octopus carries something that a store-bought toy simply cannot: the hours of care and attention that went into every stitch. A child who grows up with a handmade toy knows, on some level, that someone sat down and made that thing just for them. That is a remarkable thing to give someone.

So cast on, knit those tentacles, and bring your own eight-armed friend into the world. You will not regret it for a single stitch.
