Here are the crochet abbreviations used in this project:

  • CH: Chain

  • HDC: Half Double Crochet
  • Slip Stitch: Insert the hook, yarn over, and pull through both loops on the hook.

Important Notes & Tips:

  • Heart keychains look best in vibrant colors or contrasting shades for added charm.
  • Keep stitches even and tension consistent to avoid irregular shapes.

Gauge, Approximate Size, and Pattern Notes

Gauge: This project is forgiving in terms of gauge, but maintaining even tension is essential. No swatch is required.

Finished Size: Approximately 3 inches wide, perfect for a keychain, though you can adjust with thicker yarn or a larger hook.

Special Techniques:

  • Magic Ring: Used to create the puff flower embellishment.
  • Decreases at specific points create the curves of the heart shape.
  • Invisible join adds a professional touch to the project’s finish.

Step-by-Step Pattern

Step 1: Row 1 – Creating the Heart Base

  1. Start with a slip knot and chain 16 stitches (CH 16).
  2. Skip the first 3 chains, and into the 4th chain, make 6 double crochet stitches (DC). Including the initial chains, this gives 7 DC in the first space.
  3. Work 1 DC into each of the next 3 chains.
  4. In the next chain space:
    • Start with 1 half double crochet (HDC).
    • Perform a decrease by pulling through all 6 loops on the hook.
  5. Work 1 DC into the next 3 chains.
  6. In the last chain space, make 7 DC stitches.

Step 2: Row 2 – Shaping the Heart

  1. Turn your work. Work 1 DC in each of the first 5 stitches.
  2. Locate the 3rd stitch from the decrease in Row 1, and make 5 DC in that stitch to form the bottom point of the heart.
  3. Continue with 1 DC into each stitch across.
  4. At the end of the row, join with a Slip Stitch into the top of the first chain.

Step 3: Row 3 – Adding Definition

  1. Chain 3 (CH 3) – this counts as the first DC.
  2. In the same stitch, make another DC (increase).
  3. Work 2 DC in each of the next 6 stitches, forming the first curve.
  4. Make a decrease similar to Row 1, pulling through 6 loops for a smooth curve.
  5. Work 2 DC in the next 7 stitches for the second curve.
  6. Finish with 5 DC in the 3rd stitch from the decrease to enhance the heart shape.
  7. Slip stitch to join to the first stitch. Fasten off and leave a long tail.

Step 4: Make a Second Heart Piece

Repeat Steps 1 to 3 to create an identical second heart piece.

Step 5: Joining the Hearts and Stuffing

  1. Place the two heart pieces together with the wrong sides facing.
  2. Using contrasting yarn, start joining by single crocheting (SC) around the edge.
  3. Leave a small gap at the top for stuffing.
  4. Stuff with fiberfill, gently shaping as you go.
  5. Close the gap with SC and fasten off with a long tail. Use an invisible join for a clean finish.

Step 6: Adding the Keychain Clip

  1. Thread the long tail through the loop of the keychain clip.
  2. Secure the clip by sewing or weaving the yarn through the heart.
  3. Tie a knot for extra security and trim excess yarn.

Step 7: Adding the Puff Flower Embellishment

  1. Create a Magic Ring and chain 1.
  2. Into the ring, make 10 SC stitches and join with a slip stitch.
  3. Chain 2, then pull up 3 loops in the same stitch.
  4. Move to the next stitch, pull up 3 more loops, yarn over, and pull through all loops for the puff stitch.
  5. Repeat this process for a total of 5 puff flowers.
  6. Fasten off the yarn and tighten the ring. Secure the flower to the heart using yarn or fabric glue.
