Pattern Basic Points

Key Construction Features:

• The body is worked in the round from head to tail with continuous rounds (spiral technique).
• Simple color changes are used to create playful stripes.
• Tail and fin are crocheted directly on, requiring no separate sewing.
• Plastic eyes add a lively expression and a chain is included for optional keychain attachment.

Highlights for Crochet Structure:

• Minimal seaming: Tail and dorsal fin are made as-you-go.
• All shaping uses increases and (invisible) decreases for a smooth body.
• Fiberfill stuffing ensures a plump, squeezable result.

Special Notes

• If you change colors for stripes, always switch yarns at the end of the round and carry the previous yarn inside to keep the interior tidy.
• Use a stitch marker to track the start of each round.
• Secure all yarn tails inside the fish for a finished look.
• When stuffing, do so firmly but not overly so, to maintain the shape without stretching the stitches.

Skill Level

Beginner Friendly (Amigurumi Basics):

• Knowledge of magic circle, single crochet, increases, decreases, and simple sewing.
• Pattern uses only US crochet terms.

Materials

• 100% cotton yarn (DK or light worsted, multiple contrasting colors for stripes if desired)

• 5 mm plastic safety eyes, 2 pieces
• Polyester fiberfill stuffing
• Stitch marker

• Scissors
• Keychain ring (optional)

Measurements / Sizing

• Finished fish body (excluding tail and loop): approximately 5-6 cm (2-2.5 inches) in length.
• Tail and fins add another 1.5-2 cm to the total length.
• Keychain loop (optional): 35 chains, approx. 6-7 cm long.

Gauge

Gauge is not critical but aim for tight, even stitches so stuffing does not peek through.
5 rounds of spiraled single crochet should measure roughly 2.5-3 cm across. The body should be snug but not stiff.

• ch: Chain
• sc: Single crochet

Insert hook through the front loop of the next two stitches, yarn over, and draw through both loops, yarn over and draw through both remaining loops.

Changing Colors for Stripes:
On the last pull-through of the stitch before a color change, complete the stitch using the new color yarn.
