How to Crochet a Dolphin Keychain
Step 1: Crochet the Dolphin Body
Start with your blue yarn.
Round 1: Make a magic ring and crochet 6 single crochet stitches (SC) into the ring.
Round 2: Work an increase in every stitch. You should have 12 stitches.
Round 3: Repeat SC, INC around. You should have 18 stitches.
Rounds 4–7: Crochet 18 SC around.
Round 8: Repeat SC, DEC around until you have 12 stitches.
Add a small amount of stuffing while the opening is still accessible.
Round 9: Work 6 decreases to close the body.
Fasten off and use a yarn needle to hide the remaining yarn.
Tip: Keep the body slightly elongated rather than perfectly round. This helps create the recognizable shape of a dolphin.
Step 2: Add the White Belly
Use white or cream yarn to create a small oval-shaped belly.
Start with a short foundation chain and work single crochet stitches around both sides of the chain, adding increases at the ends.
Continue for one or two rounds until the piece is the right size.
Place the white piece on the underside of the dolphin and sew it securely into place.
The white belly creates a beautiful contrast against the blue body.
Step 3: Crochet the Dolphin Fins
Now it’s time to create the two side fins.
Using blue yarn:
- Make a short foundation chain.
- Work single crochet stitches along the chain.
- Add a few increases toward one end.
- Continue until the piece has a small triangular shape.
- Fasten off.
- Make a second matching fin.
Sew one fin onto each side of the dolphin.
Try positioning the fins slightly downward to give the dolphin a more natural swimming pose.
Step 4: Make the Tail
The dolphin’s tail gives the finished keychain its characteristic silhouette.
Create two small blue pieces shaped like rounded triangles or leaves.
Sew the two pieces together around the center, leaving the outer edges visible.
Attach the finished tail securely to the back of the dolphin.
For a more playful look, angle the tail slightly instead of attaching it completely straight.
Step 5: Add the Eye
You can use a small black safety eye for a clean amigurumi look.
Alternatively, embroider the eye with black yarn or embroidery thread.
If you’re making the keychain for a young child, embroidered eyes are generally preferable to small detachable safety components.
Step 6: Add a Tiny Crochet Star
The little yellow star is an optional decoration, but it gives the dolphin a unique handmade look.
You can crochet a tiny star using yellow yarn or embroider a simple star shape directly onto the body.
Sew it securely onto the side of the dolphin.
You can also replace the star with:
- A small heart
- Tiny flowers
- White dots
- Embroidered waves
- A name or initial
Step 7: Attach the Keychain
Finally, attach a small metal jump ring to the top of the dolphin.
Make sure it is securely fastened before connecting the keychain clasp.
If you’re using the dolphin as a bag charm, you can also attach it to a lobster clasp instead of a traditional keyring.
How to Make Your Crochet Dolphin Look More Realistic
The shape is what makes this project recognizable as a dolphin.
Instead of making a perfectly round amigurumi body, try to create a slightly longer shape with a curved back.
A few small details can make a big difference:
- Keep the snout slightly pointed.
- Make the body longer than it is wide.
- Position the fins at an angle.
- Give the tail a gentle curve.
- Use a lighter color underneath.
- Keep the eye small and simple.
These details help create the playful swimming appearance of the finished dolphin.
Color Ideas for a Crochet Dolphin
You don’t have to stick with traditional blue.
Try some of these combinations:
Ocean Blue:
💙 Royal blue + white + yellow
Soft Ocean:
🩵 Baby blue + cream + pale yellow
Pastel Dolphin:
🩷 Pink + white + lavender
Seafoam:
🌿 Mint green + cream + soft blue

Beginner Tips
If this is your first amigurumi project, don’t worry if your dolphin doesn’t look perfect on the first attempt.
The most important things are keeping your stitches consistent and counting your stitches carefully.
When stuffing the body, add small amounts at a time. Too much stuffing can make the body lose its shape, while too little can make it look flat.
Also, sew the fins and tail firmly because a keychain will be handled frequently.
Final Thoughts
