Amigurumi Frog Free Crochet Pattern: A Step-by-Step Guide to Your New Favorite Project

If you’ve ever scrolled through a craft fair or an online crochet community and stopped dead in your tracks at an impossibly cute stuffed frog sitting in someone’s palm, you’ve experienced the magic of amigurumi. These small, lovingly crafted creatures have captured the hearts of crocheters everywhere, and the frog — with its round body, bulging eyes, and tiny webbed feet — is one of the most beloved designs in the entire amigurumi universe. Whether you’re a beginner looking for your first plushie project or an experienced crocheter hunting for a free pattern to add to your collection, this guide has everything you need to bring your very own amigurumi frog to life.

Let’s talk about what makes amigurumi frogs so special, then dive straight into the free crochet pattern itself.

What Is Amigurumi?

Amigurumi (編みぐるみ) is a Japanese craft that translates roughly to “knitted stuffed toy,” though the term has expanded to include crocheted versions as well. The style is defined by its disproportionately large heads, small limbs, and undeniably charming expressions. What started as a Japanese hobby in the mid-20th century has since grown into a global phenomenon, with crafters on every continent sharing patterns, finished objects, and tips in communities both online and in person.

Crocheting amigurumi involves working in continuous rounds rather than rows, which creates a seamless, smooth surface that is perfect for stuffed animals. Most patterns use a relatively small hook and worsted or sport weight yarn to create a tight fabric that holds its shape and prevents stuffing from showing through. The frog is a particularly popular subject because its natural anatomy — round, squat, wide-eyed — translates beautifully into the amigurumi aesthetic with almost no artistic license needed.

Materials You’ll Need

Before you begin, gather your supplies. You don’t need anything elaborate or expensive. Most of what you need is probably already in your stash.

Yarn: Worsted weight yarn in your chosen frog color (green is classic, but mint, lime, teal, or even pastel lavender make gorgeous frogs) and a small amount of white or cream for the eyes. You’ll also want a tiny bit of black for the pupils if you’re not using safety eyes.

Hook: A 3.5mm (E/4) or 4mm (G/6) crochet hook works well for most worsted weight yarns. The goal is a tight gauge so stuffing doesn’t peek through. If you typically crochet loosely, go down a hook size.

Safety eyes: 12mm safety eyes give the frog that classic wide-eyed look. If you’re making this for a child under three, embroider the eyes instead using black yarn.

Stuffing: Polyester fiberfill is the standard. Use enough to make the body firm but not tight enough to distort the stitches.

Stitch marker: A simple locking stitch marker to mark the beginning of each round.

Yarn needle: For weaving in ends and sewing pieces together.

Scissors

Pattern Notes and Abbreviations

This pattern is written in US crochet terminology.

MR — Magic ring (also called a magic circle)
ch — chain
sl st — slip stitch
sc — single crochet
inc — increase (2 sc 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)
BLO — back loop only
FLO — front loop only
[ ] — repeat the instructions inside the brackets the number of times indicated
( ) — stitch count at the end of the round

The pattern is worked in continuous rounds unless otherwise stated. Do not join at the end of each round unless specifically instructed. Place your stitch marker in the first stitch of each new round and move it up as you work.

Gauge: Approximately 5 sc x 5 rounds = 1 inch. Exact gauge is not critical for amigurumi, but keeping a tight, consistent tension matters more than hitting a specific measurement.

Finished size: Approximately 4 to 4.5 inches tall seated, depending on your tension and yarn weight.

Amigurumi Frog Free Crochet Pattern

Part 1: The Body

The body is worked from the bottom up.

Round 1: Start with a MR, 6 sc into the ring. (6)
Round 2: [Inc] x6. (12)
Round 3: [Sc, inc] x6. (18)
Round 4: [Sc x2, inc] x6. (24)
Round 5: [Sc x3, inc] x6. (30)
Round 6: [Sc x4, inc] x6. (36)
Round 7: [Sc x5, inc] x6. (42)
Round 8: [Sc x6, inc] x6. (48)
Rounds 9–16: Sc around. (48) — 8 rounds even
Round 17: [Sc x6, dec] x6. (42)
Round 18: [Sc x5, dec] x6. (36)
Round 19: [Sc x4, dec] x6. (30)

Before continuing, attach your safety eyes between rounds 11 and 12, spaced approximately 10 stitches apart. If you’re embroidering eyes, you’ll do that after finishing. Begin stuffing the body now. Add stuffing gradually as you close the opening, keeping the shape round and even.

Round 20: [Sc x3, dec] x6. (24)
Round 21: [Sc x2, dec] x6. (18)
Round 22: [Sc, dec] x6. (12)
Round 23: [Dec] x6. (6)

Fasten off, leaving a short tail. Use your yarn needle to close the remaining hole by weaving through the front loops of the final 6 stitches, pulling tight. Weave in the end.

Part 2: The Eye Bumps (Make 2)

Frogs have those wonderfully prominent eyes that sit up on top of their heads. These little domes give your amigurumi frog that authentic look.

Round 1: MR, 6 sc. (6)
Round 2: [Inc] x6. (12)
Round 3: [Sc, inc] x6. (18)
Rounds 4–5: Sc around. (18)

If you haven’t already attached safety eyes to the body, you can attach them through the center of these eye bumps before sewing them on. Lightly stuff each eye bump with a small pinch of fiberfill, then sew them onto the top of the body, side by side, using your yarn needle and the yarn tail. Make sure they sit symmetrically.

Part 3: The Front Legs (Make 2)

Frog arms are short and endearing. They usually end in simple rounded paws or, if you want to get fancy, tiny fingers.

Round 1: MR, 6 sc. (6)
Round 2: [Inc] x6. (12)
Rounds 3–4: Sc around. (12)
Round 5: [Sc x2, dec] x3. (9)
Rounds 6–10: Sc around. (9)

Do not stuff the front legs. Flatten the opening at the end of Round 10 and sc across to close it, leaving a long tail for sewing. This creates a flat, sealed edge that sews neatly onto the body.

Sew the front legs onto the sides of the body, positioned around rounds 15 to 16, so they look like the frog is reaching out slightly forward. The flattened edge gives a natural, slightly outstretched appearance.

Part 4: The Back Legs (Make 2)

The back legs are what give amigurumi frogs their recognizable silhouette. They’re wider, chunkier, and bent to suggest that classic frog squat.

Foot (make 2 per leg, so 4 total):
Round 1: MR, 6 sc. (6)
Round 2: [Inc] x6. (12)
Rounds 3–5: Sc around. (12)

Fasten off one foot. Keep the other foot on your hook.

Joining the feet:
Ch 3. Sl st into the first stitch of the first foot to join. Now sc around the entire joined piece (across the second foot, along the chain, across the first foot, and along the other side of the chain). This forms a connected upper leg/thigh section.

Continue working in rounds on this joined piece:
Round 1 of thigh: Sc around the joined piece. (approximately 28–30 stitches depending on your tension)
Rounds 2–5: Sc around.
Round 6: [Sc x2, dec] repeat around to bring the count to approximately 18.
Rounds 7–9: Sc around. (18)

Do not stuff the back legs. Flatten and close the opening with a row of sc. Leave a long tail for sewing.

Attach the back legs to the bottom sides of the body, below and slightly behind the front legs, with the feet pointing outward or slightly forward to give that classic seated frog pose.

Part 5: The Mouth (Optional but Adorable)

You can leave your frog with a neutral expression or add a simple smile. For the embroidered smile, use black yarn or embroidery floss. Thread your yarn needle and bring it up through the fabric at one corner of the mouth, then stitch a simple curved U-shape across about 8 to 10 stitches below the eyes. Anchor the thread inside the body when you’re done.

For a more dimensional mouth, some crocheters cut a small oval from white craft felt and stitch it on before adding a curved red or pink embroidered line across the center, suggesting an open grin.

Part 6: Finishing Touches

Weave in all remaining ends securely. If any yarn ends are peeking through the body, use your yarn needle to pull them into the stuffing. Give your frog a gentle squeeze to even out the stuffing and check that all limbs are attached securely. If you used safety eyes, give each one a firm push to make sure the backing washer is locked in place.

If you want to add color, a small dot of pink or red embroidery floss on each cheek gives your frog a blushing, rosy expression that is absolutely irresistible.

Tips for a Perfect Amigurumi Frog

Work tight. The single most common issue beginners face with amigurumi is gaps in their fabric that let the white stuffing show through. Use a hook one or even two sizes smaller than what your yarn label recommends, and you’ll get a dense, neat fabric.

Use the magic ring. The magic ring (also called the magic circle) gives you a clean, closed center for your rounds. If you’re not familiar with it, there are dozens of video tutorials available that demonstrate it in seconds. It’s worth learning because it eliminates the gap you get when starting with a simple chain ring.

The invisible decrease is your best friend. The standard decrease in crochet creates a small bump on the right side of the fabric. The invisible decrease, worked through the front loops only of two stitches, sits flat and smooth, making your decreases nearly invisible. This matters a lot on the visible parts of your frog.

Stuff firmly but not tightly. You want the body to be nicely rounded without being so stuffed that your stitches stretch and reveal gaps. Add stuffing in small amounts and check the shape often.

Pin before sewing. Before you permanently sew any limb or eye bump onto the body, pin it in place with straight pins and hold the finished frog up to look at it from multiple angles. The placement of limbs can dramatically change the personality of the finished piece, and it’s much easier to reposition a pinned piece than to unravel stitches.

Weave in ends thoroughly. Run your end through several stitches in different directions before trimming. With amigurumi, the ends hide inside the body, but a loose end will eventually work its way out if it’s not properly secured.

Yarn Color Ideas for Your Amigurumi Frog

The classic choice is a bright medium green, and it never gets old. But part of the joy of making amigurumi is the freedom to go completely off-script with your color choices.

A mint or sage green yarn gives a soft, muted aesthetic that photographs beautifully for social media. A bright yellow-green feels tropical and cheerful. If you want to venture into fantasy territory, a deep teal or even a pale lilac frog with contrasting eye bumps is charming and unusual. Some crafters make their frogs in earth tones — olive greens and warm browns — for a more naturalistic look.

You can also stripe the body by changing yarn color every few rounds during the body section, though you’ll want to keep the striping limited to the lower half so it doesn’t interfere with the placement of the eyes and head section.

Customizing Your Pattern

One of the most rewarding things about working from a base pattern like this one is that it becomes a jumping-off point for your own creativity. Here are a few ways to customize your amigurumi frog.

Add a lily pad: Crochet a flat circle in dark green yarn (the same technique used to start the body, but continued without increases to stay flat). Stitch your frog in a seated position on top of the lily pad for a perfect display piece.

Make a tiny accessory: A small crocheted crown worked in yellow yarn turns your frog into a little royalty. A miniature bowtie stitched just below the mouth adds immediate charm. These are quick projects that make wonderful additions.

Adjust the size: Work the same pattern with a chunkier yarn and a larger hook for a jumbo frog, or use fingering weight yarn and a 2mm hook for a tiny, pocket-sized version. The proportions of the pattern scale naturally.

Keychain frog: Finish your miniature frog and attach a small keychain ring through the top of the head for an adorable bag charm.

Why Amigurumi Makes a Wonderful Gift

A handmade amigurumi frog is one of those gifts that people genuinely treasure. There’s something deeply meaningful about receiving something made by hand — the time, the attention, the intention behind it. Amigurumi frogs make wonderful baby shower gifts (use safety-eye alternatives for newborns), birthday presents, holiday gifts, or just a “thinking of you” gesture for a friend who loves frogs or animals in general.

They’re also popular at craft fairs and in online shops. If you’re considering selling your finished pieces, a cute amigurumi frog is consistently one of the best sellers in the plushie category. With a free base pattern like this one, the only investment is your time and your materials.

Storing and Caring for Your Finished Frog

Amigurumi made with acrylic yarn can usually be hand washed gently in cool water and laid flat to dry. Avoid wringing or twisting, which can distort the shape. If you used natural fibers like cotton or wool, check the yarn label for specific care instructions.

Store finished amigurumi away from direct sunlight, which can fade yarn colors over time. A simple display shelf or a small basket keeps them dust-free and looking their best.
