This charming and playful crochet fish keychain is both a delightful craft project and a perfect gift idea. Worked with Polycherry yarn and a 4/0 Tulip crochet hook, this compact fish design features textured details such as fins, tail, and a beautiful floral motif to add personality. This pattern comprises simple crochet techniques combined cleverly to achieve a unique 3D accessory. Whether for beginner or intermediate crocheters, this guide provides clear, structured instructions to create your own crochet fish keychain.

Quick Overview of Pattern

• The fish body is worked in rounds, starting with a magic ring foundation and increasing stitches for a shaped base.

• Separate fin and tail components are created and attached after the body.
• Floral petal decorative details on the body’s surface add a cute finishing touch.
• Assembly involves sewing pieces together and adding eyes and subtle decorative lines.

Notes

• Keep tension consistent to create neat, durable stitches suitable for a small accessory.
• Use stitch markers or clips optionally to mark the beginning of rounds or key positions.
• Secure yarn ends carefully by weaving them through stitches and using a lighter to seal synthetic yarn.
• Blocking is not necessary but can help shape fins or tail portions if desired.
• Ensure sturdy stitching when sewing components to withstand regular use as a keychain.

The Crochet Pattern!

Fish Body Pattern

Round 1:

• Begin with a magic ring.
• Work 12 double crochets (DC) into the ring.
• Join the round with a slip stitch to the first DC.

Round 2:

• Work into the back loops only of each stitch around for texture.
• Make 2 double crochets (DC) in each stitch (increase); repeat this across all 12 stitches.
• Total stitches for round: 24.

Round 3:

• Chain 2 to start.
• Work the pattern of 1 DC, then 1 DC increase (2 DC in one stitch), repeated 12 times around.
• Total stitches now are 36.

Round 4:

• Join the two halves together using single crochet (SC) stitches worked through the edges.
• Pattern: 2 SC, 1 SC increase (2 SC in one stitch) repeated 8 times.
• This step forms the joined body structure.
  Save

Front Decoration:

• Continue working on the front loops only.
• Work the same pattern from Round 4: 2 SC, 1 increase, twice.
• Then chain 40 to create the keychain loop.
• Finish the body by working back and forth with increases to shape firmly.

Fins and Tail Pattern

Fin Pattern:

• Start with a magic ring, chain 1, and work 6 SC into the ring.
• Round 2: Work 2 SC in each stitch, yielding 12 stitches.
• Rounds 3 and 4: Work 12 SC around to build a flat fin shape.

Tail Pattern:

• Create two identical fin-like pieces as above.
• Join these two pieces together, totaling 24 stitches.
• Work one round of single crochet (SC) around the joined tail piece.
• Perform 12 SC decreases to reduce stitch count to 12 and form the tapering tail shape.
• Finish with one more round of 12 SC for a neat edge.
  Save

Finishing Details

Floral Detail:

• On Round 2’s front loops, create six flower petals evenly spaced.
• Each petal consists of 2 chains, followed by 2 double crochets (DC) worked into the same stitch.
• This creates a delicate floral applique that decorates the fish body surface.

Final Assembly:

• Sew all parts together carefully using a tapestry needle.
  Save
• Attach small eyes—either safety eyes or embroidered ones—at the head.
• Add decorative stitching lines as preferred to enhance texture and realism.

Assembly & Finished Size

Once all parts are joined and securely sewn, your fish keychain should be approximately 7–8 cm long, with the keychain loop adding extra length for attaching keys. Ensure all ends are neatly woven in and securely trimmed. Attaching a metal keyring to the chain completed earlier finalizes your project.
