Cut thread for the first fin. Crochet the second fin following steps 1–7. Do not cut thread after finishing the second fin; proceed directly to joining the pieces.

Part 3: Joining the Parts & Body Assembly

Now, connect the tail and both fins together to continue working the main body in continuous rounds.

  1. Joining Round: Join Tail with 1 sl st, work 6 sc across the tail. Join First Fin with 1 sl st, work 15 sc across the fin. Work 7 sc across the opposite side of the tail. Work 16 sc across the second fin. [46 sts total]

Begin stuffing the body lightly and evenly with fiberfill.

  1. 7 sc, 2 dec, 7 sc, 2 dec [18 sts]
  2. (5 sc, 2 dec) repeat 2 times [14 sts]
  3. 7 dec [7 sts]

Fill the body completely with fiberfill. Keep it firm enough to hold shape, but not overly hard. Leave a long tail of yarn for sewing, then cut the working yarn.

Part 4: The Eye

Using white yarn:

  1. 6 sc in MR [6 sts]
  2. 6 inc [12 sts]
  3. (1 sc, 1 inc) repeat 6 times [18 sts]
  4. 18 sc [18 sts]

Fasten off, leaving a long tail for sewing.

Attaching the Eye:

  1. Position the white circle on the side of the head.
  2. Sew it around the edge using front loops only, adding a tiny bit of fiberfill behind the eye before closing completely.
  3. Using 2–3 strands of black embroidery floss, stitch delicate eyelashes over the top edge of the white circle.
  4. Attach the 2 mm black eye or small bead directly into the center magic ring of the white eye.

Part 5: The Lips (Make 2)

Using pink yarn (worked with the wrong side facing outwards):

  1. 5 sc in MR [5 sts]
  2. 5 sc [5 sts]

Fasten off, leaving a tail for sewing. Add a tiny piece of fiberfill if room permits.

Attaching the Lips:

  1. Sew the two lip pieces together side-by-side at their bases.
  2. Insert the base of the connected lips into the front opening of the fish head.
  3. Pull the thread ends inside the body, knot securely, and hide the yarn tails.
  4. Use the remaining yarn tail from the body to pull the head opening tightly closed around the lips.

Finishing & Decoration

  1. Close Gaps: If any small holes remain where the fins and tail were joined to the body, use a needle and matching yarn to neatly stitch them shut.
  2. Add Details: Decorate the fish body with French knots using metallic embroidery thread, or sew on small decorative seed beads to mimic scales.
  3. Attach Pin Back: Position the 1.5 cm brooch pin back horizontally on the back side of the fish and sew it securely in place using matching yarn or strong thread.

Your beautiful hand-crocheted fish brooch is now complete and ready to wear or gift!
