Materials & Tools
Here’s what you’ll need to crochet your adorable fish keychain amigurumi:
-
Yarn: Use light-weight (Category 3) or DK cotton yarn for a neat, smooth texture. Cotton holds shape beautifully and is durable for keychains. You can mix colors for stripes or fins!
-
Crochet Hook: A 2.5 mm or 3 mm hook works best for small amigurumi projects. Smaller hooks help keep the stitches tight so the stuffing doesn’t show.
-
Fiberfill Stuffing: Use a small amount of fiberfill to gently stuff the fish’s body for a soft plump look.
-
Stitch Markers: These are your best friends! They help track rounds especially when crocheting in continuous spirals.
-
Yarn Needle & Scissors: For weaving in ends neatly and trimming excess yarn once you’re done.
-
Optional Accessories: Add safety eyes for a polished finish or simply embroider tiny eyes with black thread. A keychain ring or lobster clasp transforms your cute amigurumi fish into a fun functional accessory.
Tip: If you’re new to crochet choose light-colored yarn it’s easier to see your stitches clearly!
3. Step-by-Step Instructions
Follow these beginner-friendly steps to create your crochet fish keychain pattern:
Step 1: Start the Body
Begin with a magic ring and make 6 single crochets (sc) inside it. Pull tight to close the ring this forms the top of your fish’s head.
Step 2: Shape the Fish
Work in continuous rounds, increasing gradually (e.g., 2 sc in each stitch) until the circle measures about 1.5 inches across. This will be the fish’s plump little body.
Step 3: Add Rounds for Length
Crochet several rounds without increases to build the body’s length. You can experiment with colors here maybe switch to a contrasting yarn for stripes!
Step 4: Begin Decreasing
Once you reach your desired length (around 4–5 cm), start decreasing each round by skipping every 6th or 7th stitch. Continue until only a few stitches remain open.
Step 5: Stuff Your Fish
Before completely closing fill the fish with a small amount of fiberfill stuffing. Don’t overstuff just enough to give it a round, squishy shape.
Step 6: Finish the Tail
Once the body is sealed create the tail fin by crocheting 4 chains from the back end. Add a few single crochets along those chains to give it that fin shape. Repeat on the opposite side if you’d like a double fin.
Step 7: Add Fins & Details
You can crochet small side fins separately (two little oval shapes) and sew them onto the body. Add eyes and a small mouth with embroidery thread or safety eyes.
Step 8: Attach Keychain Ring
Finally, use your yarn needle to attach the top of the fish securely to a metal keychain ring or lobster clasp.
And voilà your easy crochet fish keychain is ready to swim into your bag, purse, or gift box!
