Free Crochet Frog Keychain Pattern with Big Funny Lips

Free Crochet Frog Keychain Pattern

I love small crochet projects that can be finished without using much yarn, and this little frog is one of those projects. The green body is simple and rounded, while the oversized pink lips give it a funny expression and make the finished keychain a little different from a typical amigurumi frog.

I chose a bright green body with pink lips because the two colors stand out nicely against each other. You can, of course, change the colors to suit your own style. A darker green, yellow, blue, or even a completely different lip color can give the frog a very different look.

This frog is small enough to use as a keychain, bag charm, backpack accessory, or zipper pull. It is also a useful project for practicing basic amigurumi techniques such as working in continuous rounds, increasing, decreasing, stuffing a small shape, and sewing crocheted pieces together.

The pattern is worked in simple rounds, and the lips are crocheted separately in rows before being attached to the body. I’ll also share a few tips for keeping the small body evenly shaped and for attaching the keychain ring securely.

Finished Size

The finished frog is approximately 4–5 cm (1.5–2 inches) tall.

The final size can vary depending on your yarn, hook size, and crochet tension.

🧶 Materials & Yarn Choices

 DK or Sport-Weight Cotton Yarn (Green): For amigurumi projects like this, I always prefer mercerized cotton yarn. It gives the stitches a crisp, clean definition and prevents the stuffing from showing through. Plus, it holds its shape really well over time!

 Pink DK or Sport-Weight Cotton Yarn: Just a small scrap for the signature big lips.

 2.0 mm Crochet Hook: Using a slightly smaller hook with cotton yarn creates a tight, firm fabric so your polyfill stays securely inside.

 Fiberfill Stuffing: For shaping the body. Tip: Stuff it little by little to keep it nicely rounded without over-stretching the stitches.

 Large Googly Eyes or Safety Eyes: You can choose either, but if you’re making this for a young child, embroidered eyes are always the safest option.

 Keychain Ring & Embroidery Floss: To turn your cute frog into a durable bag charm.

Note: The frog body is worked in rounds (continuous spiral), while the lips are worked in rows (flat crochet back and forth). This helps distinguish the two parts of the pattern.

Before You Begin

The frog body is worked in continuous rounds, so there is no need to join each round with a slip stitch. A stitch marker can help you keep track of the first stitch of each round, especially because the body is small and the rounds are worked continuously.

For this project, try to keep your stitches firm and even. Small amigurumi pieces can show the fiberfill if the stitches are too loose. If you can see large gaps between the stitches while crocheting, try using a smaller hook or adjusting your tension.

When stuffing the frog, add the fiberfill in small amounts rather than filling the whole body at once. Use the end of your crochet hook, a stuffing tool, or a blunt pencil to gently push the fiberfill into the smaller areas. Turn the piece as you work so the stuffing is spread evenly.

Do not overfill the body. The frog should feel firm enough to hold its shape, but the stuffing should not stretch the crochet stitches or make the body look uneven.

Before sewing on the lips and eyes, place them on the body without attaching them first. This makes it easier to adjust their position and decide how you want the frog’s expression to look.

The finished size can vary depending on your yarn, hook size, and crochet tension. Small differences in tension are completely normal, so focus on keeping the shape even rather than trying to match an exact measurement.

Crochet Frog Body

The body is worked in continuous rounds from the bottom upward. The first four rounds gradually widen the body, the next four rounds keep the width steady, and the final rounds shape the top for closing.

Keep track of the stitch count at the end of each round. Because this is a small amigurumi piece, even one extra or missing stitch can affect the final shape.

Round 1: Make 6 SC into a magic ring. (6 sts)

Round 2: Make 1 INC in each stitch around. (12 sts)

Round 3: Repeat (1 SC, 1 INC) around. (18 sts)

Round 4: Repeat (2 SC, 1 INC) around. (24 sts)

Rounds 5–8: SC in each stitch around for 4 rounds. (24 sts each round)

These rounds keep the body at the same width and create the main rounded section of the frog. Try to keep your tension even so the sides stay smooth.

Round 9: Repeat (2 SC, 1 DEC) around. (18 sts)

Start adding the fiberfill gradually at this point. Add small amounts and spread the stuffing evenly around the inside of the body. Avoid overstuffing, as this can stretch the stitches.

Round 10: Repeat (1 SC, 1 DEC) around. (12 sts)

Add a little more fiberfill if needed, making sure the body keeps its rounded shape.

Round 11: Make DEC × 6 around. (6 sts)

Fasten off, leaving a long yarn tail. Using a yarn needle, weave the tail through the remaining front loops and pull gently to close the opening. Secure the yarn and weave in the end.

Fasten off, leaving a long enough yarn tail. Using a yarn needle, weave the tail through the remaining front loops, pull gently to close up the opening securely, and weave in the ends.

The oversized pink lips are the detail that gives this frog its funny little personality.

Shaping and Attaching the Lips

Before sewing the lips onto the frog, fold the crocheted piece slightly in the middle. This gives the lips a little more dimension instead of leaving them completely flat against the body.

Place the lips in the center of the frog’s face, just below the eyes. Pin or hold them in place first and check the position from the front.

Sew around the edges of the lip piece to secure it to the body. Add a few extra stitches through the center if needed to help maintain the slightly raised shape.

Take your time with the placement. Moving the lips just a little higher, lower, or to one side can change the expression of the finished frog.

Adding the Eyes

The eyes help give the frog its expression, so take a moment to check their position before attaching them permanently.

Place the eyes on the upper part of the frog’s face, just above the pink lips. Before securing them, move them slightly from side to side until you are happy with the expression.

If you are using safety eyes, make sure they are firmly attached. If you prefer a softer or more handmade look, you can embroider the eyes with black yarn instead.

For a child’s toy, embroidered eyes are a safer option than plastic eyes or other small detachable pieces.

Attaching the Keychain Ring

The keychain ring should be attached securely because this part will be under tension when the frog is used on keys, a bag, or a backpack.

Choose the top center of the frog’s body and pass a strong piece of green yarn or embroidery floss through several stitches. Thread it through the keychain ring and wrap it around the ring several times.

Sew through the same stitches a few times to reinforce the attachment. Pull gently to make sure the ring does not move or loosen. Once it feels secure, knot the yarn and weave the remaining ends into the body.

If you plan to use the frog as a bag charm or backpack accessory, check the attachment regularly and reinforce it if necessary.

Helpful Tips

• Keep your stitches firm and even so the fiberfill does not show through the body.
• Use a stitch marker to avoid losing track of the first stitch in each round.
• Add stuffing gradually as you work instead of filling the body all at once.
• Do not overstuff the frog. Too much fiberfill can stretch the stitches and change the shape.
• Place the eyes and lips before sewing them on permanently. Small changes in their position can give the frog a completely different expression.
• Leave long yarn tails when finishing the crocheted pieces so you have enough yarn for sewing and securing them.
• Check the keychain ring carefully after attaching it and reinforce the stitches if the ring feels loose.
• If your finished frog is larger or smaller than the example, this is normal. Yarn weight, hook size, and crochet tension all affect the final size.

Safety Notes

This crochet frog keychain is designed as a decorative accessory rather than a toy for babies or toddlers.

Plastic safety eyes, googly eyes, and metal keychain rings are small parts that may present a choking hazard if they become detached. Make sure all parts are attached securely and check them regularly during use.

For young children, embroidered eyes are a safer alternative to plastic eyes. Always supervise children around small handmade accessories.

Frequently Asked Questions

What yarn can I use?

DK or sport-weight cotton yarn works well for this project. Cotton gives the frog a firm shape and makes the small stitches easy to see.

You can use another yarn weight, but the finished size will be different.

What hook size is used?

The pattern uses a 2.0 mm crochet hook with DK or sport-weight yarn.

If your stitches are too loose, try a smaller hook to create a firmer fabric.

Why is my frog a different size?

The finished size depends on your yarn, hook, and crochet tension. Even when following the same pattern, two crocheters can end up with slightly different sizes.

Can I use a different color for the lips?

Yes. Pink is used for this version, but red, purple, white, or any color you like can work.

Can I change the eye size?

Yes. Different eye sizes will give the frog a different expression. Try placing the eyes in a few different positions before attaching them.

Can I embroider the eyes?

Yes. Embroidered eyes are a good alternative to plastic eyes, especially if you want to make the frog without detachable parts.

How do I make the lips look fuller?

Fold the lip piece slightly before sewing it onto the frog. Adding a few stitches through the center will help hold the raised shape.

Can I use the frog as a bag charm?

Yes. The finished piece can be used as a keychain, bag charm, backpack accessory, or zipper pull. Make sure the ring is securely attached before using it.

Can I sell finished frogs made from this pattern?

Finished handmade items made from the pattern can generally be sold unless the specific pattern terms say otherwise.
