Crochet Amigurumi Fish Keychain Tutorial
This crochet fish keychain stands out with its charming design and thoughtful construction. Using precise rounds of single crochet, it shapes a compact yet detailed fish body. The use of color changes, paired with neatly formed fins and tail, adds personality and texture.
Materials and Hook Selection
The project uses a 2.0 mm crochet hook and 3-ply yarn. The body of the fish begins with a magic ring, establishing a secure and tight foundation for the circular structure.
Shaping the Fish Body – Rounds 1 to 9
Rounds 1–2: Begin with 6 single crochets in the magic ring, then double up in each stitch for a total of 12.
Rounds 3–5: Gradual increases by inserting one or two single crochets per stitch result in 18 and then 24 stitches.
Rounds 6–9: Alternating one or two stitches across multiple rows expands the structure to 30 stitches.
Color Change and Body Completion
Round 10: A new color is introduced; single crochets continue evenly over 30 stitches.
Rounds 11–16: Continue increasing to 36 stitches, then maintain even rounds to build height. This completes the main body of the fish.
Tail and Fin Construction
Tail Section: A smaller segment with chains and rows of single crochets is added.
The tail is worked with 3 single crochets, turned and worked again with increases, finishing with 9 stitches.
A second tail is made symmetrically on the other side.
Final Touches and Assembly
Fins: Created using short chains and single crochets, attached by slip stitches.
Joining Parts: Slip stitches and thread cutting techniques are used to connect all parts, giving the fish a seamless and neat appearance.
The final keychain is shaped, detailed, and ready for use as a decorative or gifting item.
