Let’s hop right in.
Why You’ll Love This Frog Keychain Crochet Pattern
Before we get into the materials and instructions, let’s talk about what makes this particular pattern so special.
First, it’s small. This entire project takes up only a tiny bit of yarn, which means it’s a perfect stash buster. If you’ve been crocheting for a while, you probably have little scraps of green yarn tucked away in a basket somewhere. This frog was basically made for those scraps.
Second, it works up fast. Most crocheters finish this keychain in one to two hours. That means you can start it in the morning and have a finished gift by lunch. If you’re making them as party favors, gifts for friends, or craft fair items, you can produce several in a single sitting once you’ve memorized the pattern.
Third, it’s genuinely adorable. There’s something undeniably charming about tiny crocheted animals, and the frog’s round body, wide eyes, and stubby little legs give it so much personality. People will stop you and ask where you got it, and you’ll get to say you made it yourself.
Finally, it’s a wonderful confidence-builder for beginners. The pattern uses only a handful of basic stitches, mostly single crochets worked in a magic ring and in the round. If you’ve been wanting to try amigurumi but felt intimidated by larger projects, this mini frog is the ideal starting point.
Materials You Will Need
Gathering your supplies before you start is always a good idea. Here’s everything you need to make your frog keychain.
Yarn: A small amount of green yarn in your preferred shade. Medium weight (worsted weight, size 4) is easiest for beginners and gives nice stitch definition. You can also use DK or sport weight if you want a tinier frog, just pair it with the appropriate hook size. You’ll need a tiny bit of black or white yarn (or safety eyes can replace this entirely), and optionally a small amount of a lighter green or yellow-green for the belly.
Crochet Hook: A 3.5mm or 4.0mm hook works well with worsted weight yarn. If you’re using thicker yarn or prefer a looser tension, go up to a 4.5mm.
Safety Eyes: Two 6mm black safety eyes give the frog a great finished look. If you’re making this for a small child, omit the safety eyes and embroider the eyes instead using black yarn.
Polyfill Stuffing: A small amount of polyester fiberfill stuffing to give the frog’s body its round, plump shape.
Stitch Marker: A locking stitch marker or a scrap piece of yarn to mark the beginning of each round.
Yarn Needle: A blunt tapestry needle for weaving in ends and sewing pieces together.
Scissors: For cutting yarn.
Keychain Ring: A metal split ring keychain, which you can find at any craft store or online. You’ll also want a small length of chain or a lobster clasp if you want to give the frog a bit of a dangle.
Optional: A small amount of pink yarn or embroidery floss for the mouth detail.

The Frog Keychain Free Crochet Pattern
Now for the fun part. Let’s work through each piece step by step.
The Body
The body is the main piece of the frog and the largest section you’ll crochet. It’s worked from the bottom up in a continuous spiral.
Round 1: Start with a magic ring. Work 6 sc into the ring. Pull the tail to close the ring. (6 stitches)
Round 2: Inc in every stitch around. (12 stitches)
Round 3: (Sc 1, inc) repeat around. (18 stitches)
Round 4: (Sc 2, inc) repeat around. (24 stitches)
Round 5: (Sc 3, inc) repeat around. (30 stitches)
Rounds 6–10: Sc in every stitch around. (30 stitches per round — work these five rounds without any increases or decreases to form the middle of the body)
Before you begin decreasing, this is the time to insert your safety eyes. Place them between rounds 7 and 8, spaced about 6 to 8 stitches apart. Once the safety eyes are secured, you can begin adding fiberfill stuffing as you decrease. Don’t overstuff — a lightly filled frog looks rounder and more natural than one packed too tightly.
Round 11: (Sc 3, dec) repeat around. (24 stitches)
Round 12: (Sc 2, dec) repeat around. (18 stitches)
Round 13: (Sc 1, dec) repeat around. (12 stitches)
Make sure your stuffing is complete at this point. The opening will get small quickly.
Round 14: Dec around. (6 stitches)
Fasten off, leaving a tail. Use your yarn needle to close the remaining opening by weaving the tail through the front loops of the remaining 6 stitches and pulling tight. Weave in the end securely.
The Front Legs (Make Two)
The front legs are small and simple. They give the frog a lot of charm and are worked very quickly.
Round 1: MR, 6 sc. (6 stitches)
Round 2: Sc in each stitch around. (6 stitches)
Round 3: Sc in each stitch around. (6 stitches)
Round 4: Sl st in first stitch to close.
Fasten off, leaving a long tail for sewing. Don’t stuff the legs — they look better flat and floppy.
The Back Legs (Make Two)
The back legs are slightly larger and bent to give the impression of a frog sitting in its natural resting pose.
Round 1: MR, 6 sc. (6 stitches)
Round 2: Inc in every stitch. (12 stitches)
Round 3: Sc in each stitch around. (12 stitches)
Round 4: Sc in each stitch around. (12 stitches)
Round 5: Sc in each stitch around. (12 stitches)
Fold the piece slightly and sl st across to close, creating a flat, slightly curved leg shape. Fasten off, leaving a long tail for sewing. Again, do not stuff.
The Eyes (Optional Raised Eye Bumps)
If you’re using safety eyes, you can skip this section. But if you want to give your frog the classic wide, bulgy eyes that make frogs so recognizable, you can crochet small raised bumps and attach them to the top of the head.
Round 1: MR, 6 sc. (6 stitches)
Round 2: Inc in every stitch. (12 stitches)
Round 3: Sc in each stitch around. (12 stitches)
Slip stitch to close and fasten off, leaving a tail for sewing. Make two. Lightly stuff each bump before sewing closed, and attach your safety eye through the center of each bump before sewing them to the head.
Assembling Your Frog Keychain
Assembly is where your frog truly comes to life. Take your time with this step and use plenty of pins to position each piece before sewing.
Attaching the Front Legs: Position the front legs on either side of the body, roughly at the equator. They should angle slightly downward and outward, as if the frog is reaching its arms out. Sew each one securely using the long tail and a yarn needle, making sure to catch several stitches on both the leg and the body.
Attaching the Back Legs: The back legs attach near the bottom of the body, slightly toward the back. Angle them outward and slightly upward so the frog appears to be sitting. You want the frog to sit flat and balanced, so test the positioning before sewing. If one leg is placed higher than the other, the frog will lean to one side.
Adding the Mouth: Using a length of black embroidery floss or a strand of black yarn, embroider a small curved smile just below the eyes. A simple straight stitch curving upward at each end is all you need. Some crafters also add a small pink tongue by sewing a single short stitch in the center of the mouth using pink floss.
Attaching the Keychain Ring: This is the final step. Cut a short piece (about four inches) of your green yarn and fold it in half. Thread the folded end through your keychain ring to create a loop, then bring the two loose ends through the loop and pull tight to secure the yarn to the ring. Thread the two ends through the top of your frog’s head using your yarn needle, then tie them in a firm knot inside the body to secure. Alternatively, you can sew a small loop of yarn to the top of the frog’s head and attach the keychain ring directly to the loop.
Tips for Making the Perfect Frog Keychain
Making a small amigurumi project like this keychain comes with its own set of tips and tricks. Here are a few things that will help everything go more smoothly.
Tight tension is your friend. When making amigurumi, you want a tighter tension than you might use for blankets or garments. A tight stitch means the stuffing won’t show through and the frog will hold its shape better. If you can see through your stitches when you hold the piece up to the light, try going down one hook size.
Use a stitch marker religiously. It’s incredibly easy to lose track of where your round begins and ends on a small piece. Move your marker at the start of every round without exception.
Don’t skip the invisible decrease. The invisible decrease (also called the magic decrease) is worked through the front loops only of two consecutive stitches. It creates a much neater finish than a standard decrease and prevents the unsightly bump that a regular decrease can leave. It’s worth the small extra effort.
Pin before you sew. Before you commit to sewing any piece onto the body, use pins or stitch markers to hold everything in place and stand back to check the positioning. A limb that’s just slightly off-center can make the whole frog look lopsided, and it’s much easier to adjust before sewing than after.
Weave in ends thoroughly. On small projects, there’s a temptation to cut corners on finishing. Resist it. Weave in your ends through multiple stitches in different directions to make sure nothing unravels, especially on a keychain that will be handled frequently.
Color and Customization Ideas
One of the best things about this pattern is how easily it lends itself to customization. Here are some ideas to make your frog uniquely your own.
Try making a gradient frog using self-striping yarn that shifts through multiple shades of green. The color changes happen automatically as you work, giving the frog an unexpected and beautiful look with no extra effort.
Make a poison dart frog by swapping out the green yarn for bright colors — electric blue, vivid orange, or bold yellow. These tropical beauties are just as cute as their green cousins.
Add a tiny accessory. A miniature bow tie or a small flower attached to the frog’s head takes just a few extra minutes and makes the keychain look like a finished, polished product. These little details are particularly nice if you’re making frogs as gifts.
Try different eye styles. Big white felt circles with smaller black circles glued on top give the frog a more cartoon-like look. Embroidered eyes in white and black can give a more subtle, soft toy feel. Experiment to find the look you love.
Crochet a tiny lily pad in flat green rounds and attach your frog to it for a decorative display piece rather than a keychain.
Who This Pattern Is Perfect For
This pattern is genuinely accessible to a wide range of skill levels. If you’ve completed your very first crochet project — even just a simple square — and you’re comfortable with single crochet and working in the round, you can make this frog. There are no tricky stitches, no unusual techniques, and no complicated shaping.
For intermediate crocheters, this is a satisfying quick project to pick up between larger works. It’s the kind of thing you crochet while watching a movie, or take along to a coffee shop in your bag.
For experienced crocheters, consider using this as a pattern base to design your own variations. The basic body shape is versatile enough to become the foundation for many different animals with small adjustments to the color, limb placement, and facial details.
Teachers and group leaders running craft sessions will find this pattern particularly useful. It’s short enough to complete in a single session, uses very little material, and produces a finished item that participants can take home — all qualities that make for a satisfying class project.
Storing and Caring for Your Frog Keychain
Since your frog keychain will be attached to your keys or bag and handled frequently, it’s worth knowing how to keep it looking its best.
Most acrylic yarn can be spot-cleaned with a damp cloth and a small amount of mild soap. If the frog gets particularly grubby, you can hand-wash it gently in cool water and reshape it while damp, then allow it to air dry completely before using it again.
Avoid machine washing unless you know your yarn is specifically labeled as machine-washable, since agitation can cause the stuffing to shift or felt the yarn.
If the frog loses its shape over time, a very light stuffing with a new bit of fiberfill (by opening a seam, re-stuffing, and sewing closed again) will restore its plumpness.
A Few Final Thoughts
There’s something deeply joyful about making small, handcrafted things. A frog keychain might seem like a tiny, inconsequential project compared to a full blanket or a garment, but don’t underestimate what it represents. Every stitch is made by hand, shaped by your fingers, and finished with care. The person who receives one of these little frogs as a gift will know that someone took time and thought and skill to make something specifically for them.
This frog keychain free crochet pattern is the kind of project that quietly builds your skills — your tension becomes more consistent, your shaping gets neater, your finishing work gets cleaner — all while producing something you’re genuinely proud of.
We hope this pattern from The Crochetry brings you a lot of joy, and that your little green friend brings a smile to everyone who sees it dangling from your keys.
Happy crocheting, and as always, keep making beautiful things.
