The Crochet Pattern

Part 1: The Caterpillar Body

Step 1: Foundation
  1. Begin with a slip knot.
  2. Chain 40 to create the foundation for the spiral.

Step 2: Row 1
  1. Skip the first chain (nearest to the hook).
  2. In the 2nd chain, work:
    • 1 single crochet (SC).
    • 1 single crochet in the next chain.
  3. In the next chain, work 3 half double crochets (HDC) into the same chain.
  4. For the remaining chains:
    • Work 3 double crochets (DC) into each chain until you reach the final chain in the row.
  5. In the last chain, work 1 slip stitch (SL ST) to secure the row.

Step 3: Shaping the Spiral
  1. The completed row will appear bunched up and wavy. Gently use your fingers to twist the fabric into a circular spiral shape, ensuring an even and neat shape.

Step 4: Create Tentacles
  1. For the first tentacle:
    • Chain 10.
    • Starting from the 2nd chain from the hook, work slip stitches (SL ST) back down to the base of the chain.
  2. For the second tentacle:
    • Chain 10 again and repeat the same process, working slip stitches back down to the base of the chain.
  3. Once both tentacles are complete:
    • Work 1 slip stitch into the base of the spiral to secure the tentacles.
    • Fasten off and hide the yarn tail neatly using the yarn needle.

Part 2: The Heart Charm

Step 1: Create the Base
  1. Make a magic ring by wrapping yarn around your fingers, crossing it to form an "X." Insert the hook under the first strand, grab the second strand, and pull it through to form a loop. Secure with a chain.

Step 2: First Half of the Heart
  1. Chain 4.
  2. Work 3 triple crochets (TRC) into the magic ring.
  3. Next, work 4 double crochets (DC) into the magic ring.
  4. Chain 1.

Step 3: Second Half of the Heart
  1. Work 1 triple crochet (TRC) into the ring.
  2. Chain 1, then work 4 double crochets (DC) into the ring.
  3. After the double crochets, work 3 triple crochets (TRC) into the ring.
  4. Chain 4 to finish the second half.

Step 4: Shaping and Finishing
  1. Slip stitch into the magic ring to secure.
  2. Pull the tail of the magic ring to close the center tightly.
  3. Fasten off and secure the yarn tail by weaving it into the work.

Step 5: Create and Assemble the Second Heart
  1. Make a second identical heart using the same steps.
  2. Place the hearts back-to-back with wrong sides facing each other.
  3. Join the hearts at their edges:
    • Work slip stitches (SL ST) through the back loops of each corresponding stitch from both hearts.
    • Continue joining until the hearts are securely stitched together.
  4. Before closing the final stitch, tuck any loose threads between the hearts.
  5. Complete the joining with a slip stitch, fasten off, and weave in the tail.

Final Assembly

  1. Attach the Wooden Bead:
    • Insert the caterpillar tentacles into the hole of the wooden bead. Adjust to create a “face” for the caterpillar.
  2. Connect the Charm and Keyring:
    • Use the remaining yarn to attach the heart charm to the keyring securely.
  3. Glue the Heart to the Caterpillar:
    • Use a small amount of multi-purpose glue to attach the heart directly to the spiral caterpillar body. Allow the glue to dry completely.
