Free Alien Crochet Pattern: How to Make Your Own Out-of-This-World Amigurumi

If you’ve ever looked up at the night sky and wondered what’s out there, this free alien crochet pattern is your chance to bring a little extraterrestrial magic down to Earth — one stitch at a time. Whether you’re a seasoned crocheter looking for your next fun project or a beginner who wants to try amigurumi for the first time, this pattern is approachable, customizable, and completely free. By the end of this post, you’ll have everything you need to make your very own little green (or purple, or teal, or whatever color feels right to you) alien friend.

Let’s get into it.

Why You’ll Love This Alien Crochet Pattern

Amigurumi — the Japanese art of crocheting or knitting small, stuffed creatures — has taken the crafting world by storm, and for good reason. These little characters are portable, beginner-friendly once you get the hang of the magic ring, and endlessly customizable. Aliens are particularly fun to make because there are no rules. No one can tell you your alien has the wrong number of eyes or the wrong shade of green. The galaxy is literally your limit.

This free alien crochet pattern creates a finished amigurumi that stands roughly 5 to 6 inches tall, making it a perfect size for a desk companion, a holiday ornament (add a ribbon loop to the top), a gift for a sci-fi fan, or a toy for kids aged three and up. The entire project can usually be completed in a single afternoon or evening, which makes it incredibly satisfying even for crafters with busy schedules.

Materials You’ll Need

Before you get started, gather your supplies. You probably already have most of these at home if you crochet regularly.

Yarn: Worsted weight yarn in your main color (green is classic, but sky blue, mint, lavender, or even hot pink all look amazing). You’ll also need a small amount of white and black for the eyes, and an optional accent color for any details you want to add.

Hook: A 3.5mm or 4mm crochet hook works best for worsted weight yarn when making amigurumi. You want your stitches tight enough that the stuffing doesn’t peek through.

Notions: Polyester fiberfill stuffing, a yarn needle for sewing pieces together, stitch markers (at least two), scissors, and safety eyes if you prefer them over embroidered eyes. Safety eyes in 12mm or 15mm work beautifully for this pattern. If you’re making this for a child under three years old, always embroider the eyes instead of using safety eyes, which can be a choking hazard.

Optional: Wire armature if you want your alien’s arms to be poseable. This is a fun touch for display pieces.

Abbreviations Used in This Pattern

If you’re new to amigurumi patterns, here’s a quick key so you can follow along easily.

MR = magic ring
ch = chain
sc = single crochet
inc = increase (two single crochets in the same stitch)
dec = invisible decrease (insert hook through the front loops of the next two stitches, yarn over, pull through, yarn over, pull through both loops)
sl st = slip stitch
FO = fasten off
BLO = back loops only
st = stitch
rnd = round

All rounds are worked in a continuous spiral unless otherwise noted. Use a stitch marker to mark the first stitch of each round.

Free Alien Crochet Pattern: Step-by-Step Instructions

Head

The head is the most prominent part of your alien and gives it that iconic extraterrestrial shape — big at the top, slightly narrower at the chin.

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc repeat around. (18 sts)
Rnd 4: Sc 2, inc repeat around. (24 sts)
Rnd 5: Sc 3, inc repeat around. (30 sts)
Rnd 6: Sc 4, inc repeat around. (36 sts)
Rnd 7: Sc 5, inc repeat around. (42 sts)
Rnds 8–14: Sc in each st around. (42 sts)
Rnd 15: Sc 5, dec repeat around. (36 sts)
Rnd 16: Sc 4, dec repeat around. (30 sts)

At this point, if you’re using safety eyes, insert them between rounds 11 and 12, about 8 to 10 stitches apart. This wide spacing gives the alien that characteristic large-eyed look. If you want a cyclops alien, place a single large eye centered on the face — completely valid, totally charming.

Rnd 17: Sc 3, dec repeat around. (24 sts)

Begin stuffing the head firmly. Continue stuffing as you close up.

Rnd 18: Sc 2, dec repeat around. (18 sts)
Rnd 19: Sc 1, dec repeat around. (12 sts)
Rnd 20: Dec repeat around. (6 sts)

FO, leaving a short tail. Use your yarn needle to close the remaining hole by weaving through the front loops of the remaining stitches and pulling tight. Weave in end.

Body

The body is worked from the bottom up and is slightly smaller than the head, which gives amigurumi characters their characteristic top-heavy, cute appearance.

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc 1, inc repeat around. (18 sts)
Rnd 4: Sc 2, inc repeat around. (24 sts)
Rnd 5: Sc 3, inc repeat around. (30 sts)
Rnds 6–12: Sc in each st around. (30 sts)
Rnd 13: Sc 3, dec repeat around. (24 sts)
Rnd 14: Sc 2, dec repeat around. (18 sts)

Stuff the body firmly before closing.

Rnd 15: Sc 1, dec repeat around. (12 sts)
Rnd 16: Dec repeat around. (6 sts)

FO and close the hole as you did with the head.

Arms (Make 2)

The arms are simple tubes that give your alien a friendly, slightly floppy feel. You can make them as long or short as you like.

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnds 3–10: Sc in each st around. (12 sts)

Lightly stuff the arm — you don’t want it to be too stiff unless you’re using wire armature. Flatten the top of the arm and work a row of sc across to close it. This creates a neat, flat edge that’s easy to sew onto the body.

FO, leaving a long tail for sewing. Make two.

Legs (Make 2)

The legs give your alien a sturdy base to stand on (or sit on, depending on how you position them).

Rnd 1: MR, 6 sc into ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: Sc in BLO of each st around. (This creates a little ridge for the foot.) (12 sts)
Rnds 4–9: Sc in each st around. (12 sts)

Stuff the leg lightly. Flatten and close the top as you did with the arms.

FO, leaving a long tail for sewing. Make two.

Antennae (Make 2)

What’s an alien without antennae? These little details are what really sell the extraterrestrial look.

Rnd 1: MR, 4 sc into ring. (4 sts)
Rnds 2–7: Sc in each st around. (4 sts)

Do not stuff. Flatten and pinch the top closed. FO, leaving a long tail. Make two.

If you want little balls on the ends of the antennae — which looks adorable — make two tiny bobbles by working a MR with 6 sc, pulling tight, fastening off, and sewing one to the top of each antenna before attaching them to the head.

Ears (Optional)

Some alien designs include small pointed ears on the sides of the head. If you want to add these:

Rnd 1: MR, 3 sc into ring. (3 sts)
Rnd 2: Inc in each st around. (6 sts)
Rnd 3: Sc 1, inc repeat around. (9 sts)
Rnd 4: Sc in each st around. (9 sts)

FO, leaving a long tail. Do not stuff. Fold slightly and sew onto the sides of the head.

Assembling Your Alien

Assembly is where your alien really comes to life, and it’s worth taking your time with this step.

Start by pinning all pieces to the body and head before you sew anything. Use pins or small clips to test different placements and find the look you love. Some crafters prefer the head and body attached at a slight angle for a more dynamic, playful pose. Others like everything centered for a cleaner look.

Attach the head to the body first, using your yarn needle and a length of the main color yarn. Sew all the way around the neck opening, catching stitches from both pieces, and pull snug. Go around twice for a secure join.

Next, sew the legs to the bottom of the body. Place them symmetrically, roughly 8 to 10 stitches apart, with the flat closed edges facing upward and inward. Sew through several layers to make sure they’re secure.

Attach the arms to the upper sides of the body, positioning them just below where the neck joins the body. Angle them slightly downward and forward if you want your alien to look like it’s reaching out for a hug.

Finally, attach the antennae to the very top of the head, a few stitches apart. If you made ears, sew those on at about round 12 of the head, on either side, halfway between the top and the eyes.

Adding Details and Personality

This is the part where your alien becomes yours. Here are some fun ways to customize:

Mouth: Use black embroidery floss or a small length of dark yarn to stitch a simple smile, a wide grin, or even a tiny surprised “o” shape. A curved smile works best between rounds 14 and 15, centered below the eyes.

Nose: A few satin stitches in a slightly darker shade of your main color, or three tiny vertical stitches in black, make a subtle but effective nose.

Blush marks: Use a pink or peach colored pencil or a touch of chalk pastel lightly rubbed onto the cheeks for a sweet, rosy glow. Set it with a tiny spritz of craft sealant if you want it to last.

Belly button or body details: A small French knot or a tiny button sewn to the middle of the body adds a fun extra detail.

Spots or stripes: Use a contrast color yarn to surface embroider little spots, stripes, or even tiny star shapes onto your alien’s body.

Galaxy eyes: Instead of plain safety eyes, look for holographic or AB (aurora borealis) finish safety eyes, which catch the light beautifully and give your alien an otherworldly sparkle.

Yarn Color Ideas

One of the most fun parts of making this alien crochet pattern is choosing your color palette. Here are some combinations that work really well:

Classic Roswell green with black eyes is the iconic choice, timeless and immediately recognizable. A pale mint or seafoam green with iridescent safety eyes feels more modern and ethereal. Deep teal with copper or gold eyes has a sophisticated, almost steampunk alien vibe. Lavender or soft purple with pink blush marks and white eyes is sweet and approachable, perfect for a baby gift. Bright turquoise with neon yellow accents is bold, fun, and very on-trend in the amigurumi community right now. Black or charcoal with silver details reads as sleek and mysterious — a more serious alien for the sci-fi purist.

Don’t be afraid to mix yarn weights or textures either. A slightly fuzzy yarn for the body with a smooth yarn for the head creates a fun contrast. Adding a metallic thread carried along with your main yarn gives the whole alien a subtle shimmer.

Tips for Beginners

If this is your first amigurumi project, a few things will make a big difference in your finished result.

Use a smaller hook than the yarn label recommends. Most yarn labels suggest a 5mm or 5.5mm hook for worsted weight, but amigurumi worked at that gauge will have gaps that let stuffing show through. Going down to a 3.5mm or 4mm creates a tighter, cleaner fabric.

Don’t skip the stitch marker. Amigurumi is worked in a continuous spiral, not in joined rounds, so it’s easy to lose track of where one round ends and the next begins. A simple piece of scrap yarn looped through your first stitch of each round solves this completely.

Stuff as you go. Once an opening gets too small, it becomes very hard to stuff evenly. Begin adding fiberfill when your piece is about two-thirds closed, and keep adding small amounts as you finish each decrease round.

Master the invisible decrease. Regular decreases in amigurumi create a visible line that can look a bit untidy. The invisible decrease — working through only the front loops of two stitches — creates a much smoother finish and is worth learning right from the start.

Weave in your ends thoroughly. Amigurumi gets handled, squeezed, and loved, so take the time to weave ends in multiple directions before trimming.

Frequently Asked Questions About This Pattern

Can I sell items made from this pattern? This is a free pattern shared for personal and small-scale handmade business use. You’re welcome to sell finished aliens made from it, but please don’t reproduce or sell the pattern itself.

What if I want to make a bigger alien? Simply go up a hook size and use bulky weight yarn, or work two strands of worsted weight held together. Your finished alien will be roughly proportionally larger.

How do I make the alien stand up on its own? The key is firm, even stuffing in the body and legs, and positioning the legs slightly forward when you sew them on. You can also hot-glue a small circle of craft foam to the bottom of the body as a base.

Can I use this pattern to make a keychain? Absolutely. Work the pattern with fingering weight yarn and a 2mm hook, skip the ears, and attach a lobster clasp through a small chain loop at the top of the head.

My magic ring keeps coming loose. What should I do? Try the adjustable ring method and then, after you’ve worked your first round of increases, pull the yarn tail firmly to close the ring completely and weave it in immediately through multiple stitches to lock it in place.

Sharing Your Finished Alien

Once your alien is complete, take a moment to photograph it before gifting it or keeping it. Natural light works best — set your alien near a window on an overcast day for soft, even lighting that really shows off the texture of the stitches. A simple background, like a piece of kraft paper or a wooden surface, keeps the focus on your little creation.

If you share your finished alien on social media or craft platforms like Ravelry, Instagram, or Pinterest, it would be wonderful to tag it so others can find the pattern and make their own. The amigurumi community is one of the warmest corners of the internet, and seeing what other makers do with a pattern is always inspiring.

Whether your alien ends up on a child’s bookshelf, clipped to a backpack, hanging from a Christmas tree in December, or sitting on your own desk keeping you company through long workdays, it carries with it all the care and creativity you put
