Step 1: Magic Ring

Start with a magic ring (alternatively, initiate with a chain of 4 and slip stitch to form a ring).

Step 2: Round 1

Inside the magic ring:

Chain 3 (this counts as the first double crochet),
3 double crochets,
3 half double crochets,
1 double crochet,
1 treble crochet,
1 double crochet,
3 half double crochets,
3 double crochets,

Finish with a chain of 3 and slip stitch into the center of the magic ring.
Tug the tail of the magic ring to tighten it up. You now possess a heart shape.

Step 3: Round 2

Chain 3 and slip stitch into the same stitch.
Continue working into the subsequent stitches:
2 single crochets into each of the next 2 stitches,
2 half double crochets into the next 3 stitches,
1 half double crochet,
In the treble crochet stitch from the last round, perform 1 half double crochet, chain 3, and slip stitch back into the same stitch (this forms the apex of the heart),
Proceed with: 1 half double crochet into the next stitch,
2 half double crochets into each of the following 3 stitches,
2 single crochets into each of the next 2 stitches.
Chain 3, slip stitch to the heart’s center, and fasten off.

Step 4: Complete the Heart

Weave in the ends using the yarn needle.
For a more dimensional heart, consider crocheting two hearts and stitching them together, leaving a small opening for stuffing before closing it.

Step 5: Attach Keychain

Employ the yarn needle to sew the heart onto a keychain ring.
Ensure it is secured tightly and tuck in any loose ends.

Optional: Personalize It

Add embellishments: Incorporate beads or embroidery for added flair.
Experiment with sizes: Use bulkier yarn for a larger heart or finer yarn for a smaller, delicately crafted heart.

Your crocheted heart keychain is now complete! This quick and easy craft makes it an ideal handmade Valentine’s Day present.
