If you are new, take a moment to practice these before continuing.
Gauge and Size Information
Gauge
- 16 stitches x 10 rounds = 10 cm
Finished Size
- Approximately 10–15 cm (4–6 inches)
Adjusting Size
To make a larger fish:
- Use thicker yarn
- Increase hook size
- Add more increase rounds
To make a smaller fish:
- Use thinner yarn
- Reduce stitch count
Step-by-Step Instructions (Very Detailed)
Now let’s begin building your crochet fish.
Step 1: Start with Magic Ring
- Create a magic ring
- Work 6 single crochet (sc) into the ring
- Pull tight
Tip: Keep stitches tight to avoid holes.
Step 2: Increase Rounds (Building the Body)
- Round 2: inc in each stitch (12 sts)
- Round 3: (1 sc, inc) repeat (18 sts)
- Round 4: (2 sc, inc) repeat (24 sts)
- Round 5: (3 sc, inc) repeat (30 sts)
You are now forming a rounded body.
Step 3: Body Length
- Work 5–7 rounds of sc (no increases)
- This builds the fish’s body length
Tip: This is where you can change colors for stripes.
Color transitions are commonly used in sea creature patterns to create visual texture .
Step 4: Begin Decreasing
- Round: (3 sc, dec) repeat
- Next: (2 sc, dec) repeat
- Next: (1 sc, dec) repeat
Start stuffing the fish before closing.
Step 5: Closing the Body
- Continue decreasing until small opening
- Finish with slip stitch
- Fasten off
Step 6: Tail Creation
- Attach yarn at the back
- Chain 10
- Work back with:
- sc
- hdc
- dc
- Repeat for second side
This creates a soft, fan-shaped tail.
Step 7: Side Fins
- Attach yarn on side
- Chain 3
- Make 2 dc in same stitch
- Slip stitch
Repeat on the other side.
Step 8: Eyes and Details
Options:
- Safety eyes (insert before closing body)
- Embroidered eyes
- Small stitched mouth
Tip: Small details bring personality to your fish.
Tips for Beginners
Use Tight Stitches
Loose stitches cause stuffing to show.
Mark Your Rounds

Stuff Gradually
Don’t overstuff — it distorts shape.
Practice Decreases
Clean decreases make your project look professional.
Common Mistakes and Fixes
