Beautiful Free Crochet Fish Keychain Pattern to Brighten Up Your Everyday Essentials

Crocheting this fish involves working with single crochet (SC) stitches, making it ideal for beginners and those looking for a quick project. The magic circle technique used to form the fish's body ensures a neat and tight start. You'll also enjoy switching between yarn colors to create eye-catching stripes. The special techniques also include double crochet (DC) and treble crochet (TR) stitches, which are used to shape the fins and tail. Once you master these stitches, they open the door to make other small items, like crochet flowers, hearts, or even mini sea creatures to pair with this fish.

The Step-by-Step Pattern

Fish Body

Round 1:

Make a magic circle.
Chain 1. Work 6 single crochets (sc) into the ring.
Pull the tail to tighten the ring.

For beginners: Start by making a loop with your yarn (magic circle), chain once to secure, and then place 6 single crochets into that loop. Pull the end gently to close the hole.

Round 2:

Work 1 sc in the first stitch,
2 sc in the next stitch (increase).
Repeat (1 sc, 2 sc in next) around for the round. (9 stitches total).

Work one single crochet, then two in the next stitch, repeat until you finish the circle for gentle shaping. This round creates a slight oval, a "fishy" body!

Round 3:

Work 1 sc in each of the next 2 stitches,
2 sc in the next stitch (increase).
Repeat (2 sc, inc) around. (12 stitches total)

Crochet one single crochet in each of the next 2 stitches, two in the third. Repeat for a smooth body expansion.

Round 4:

Change to white (or contrast color) at last stitch:
- 3 sc, increase in the next stitch. Repeat (3 sc, inc) three times (total 15 stitches).

Work three single crochets, two in next. Repeat. Finish last stitch with new color (see color change tip below).

Round 5:

With white:
- 4 sc, increase.
- Repeat (4 sc, inc) three times (18 stitches total).
- Color change to blue in last stitch.

Change colors at the end by pulling through the new yarn before completing the final stitch; this yields tidy stripes.

Round 6:

With blue:
- 5 sc, increase.
- Repeat (5 sc, inc) three times (21 stitches).
- Color change to white at the end.

Round 7:

With white:
- 6 sc, increase.
- Repeat (6 sc, inc) three times (24 stitches).
- Color change to blue at the end.

Round 8:

With blue:
- 7 sc, increase.
- Repeat (7 sc, inc) three times (27 stitches).
- Cut white yarn; continue with blue only.

Round 9:

With blue only:
- 8 sc, increase.
- Repeat (8 sc, inc) three times (30 stitches).

Round 10:

9 sc, increase.
Repeat (9 sc, inc) three times (33 stitches).

*To simplify: Work each round in a spiral, placing increases as stated (after every 1, 2, 3… stitches), and always finish the final stitch before a color change with your new yarn for crisp stripes.

Finishing the Body

Slip stitch to the next stitch. Fold the fish body in half, lining up the edges.
Chain 1. Single crochet through both layers to close the body, working through matching stitches on each side. Continue across, leaving no opening.
Chain 1, cut yarn, pull end through to fasten off.
Weave in tails neatly along seam for a clean finish.

Fold body in half lengthwise, closing with single crochets through both front and back stitches ("whipstitch" with sc).

Tail Fin

With white yarn, skip 5 stitches from body seam, insert hook into 6th stitch.
Pull up a loop, chain 3 (counts as first double crochet).
Into same stitch: 1 more double crochet (2 dc in same stitch).
Next 4 stitches: 1 treble crochet (yarn over twice before inserting hook) into each.
Next stitch: 1 double crochet.
Chain 3, slip stitch into same stitch as last dc.
Chain 1, fasten off, weave in ends.

This creates a fan-shaped tail. The use of treble crochets (long, open stitches) makes it flexible and wavy!

Side Fins (Make 2)

With white yarn, make a magic circle.
Chain 3, work 4 double crochets into ring (5 dc total).
Chain 3, slip stitch into ring.
Chain 1, fasten off. Pull tail to close circle. Secure and weave in both tails.

Make two; these will be sewn or glued to the sides of your fish for cute, puffy pectoral fins!

Assembly

Attach eyes: Glue flat black beads or stitch/embroider eyes near the front stripe of your fish.
Attach fins: Using glue or needle and thread, affix one fin to each side.
Attach tail: Make sure it is centered at the back.
Attach keychain ring: Open ring, insert through top of fish, close securely.

Simple assembly - use glue or needle as you prefer for secure finishing.
