About this pattern
This puffy heart starts life as two matching halves, each built from a magic ring and worked flat through nine rounds before they're joined into one plump shape. Every round adds shaping, so the piece grows from a tight little circle into a rounded lobe ready to be paired with its twin. Because both halves follow the same nine rounds, once the first is done, the second moves fast.
The early rounds carry the workload: increases stack up quickly to swing the stitch count wide, then later rounds settle into steadier shaping to pull the heart lobes into place. Slow down right where the increase pattern shifts from stitch-and-stitch to stitch-and-inc, since that's where the curve of the heart actually forms. A dropped increase here throws off the whole silhouette, so count before moving on.
- Start each half with a magic ring, then close it tight before working the first round of single crochets.
- Build up the round count with steady increases that flare the circle out into a heart lobe shape.
- Drop a stitch marker into the first stitch of each round to keep track of where rounds begin and end.
- Repeat the same round sequence to make a second matching half for the other side of the heart.
- Hold both halves together and single crochet around the outer edge to fuse them into one piece.
- Stuff the heart before the seam closes fully, then finish joining and tuck in the last stitches.
What goes wrong
- Loose magic ring center Pull the tail firmly before working the first round so no hole remains at the tip of the heart.
- Losing track of round starts Move the stitch marker into the first stitch of every new round instead of leaving it behind, so the join point stays accurate.
- Uneven increase placement Work each increase directly into the stitch it belongs to rather than shifting it over, or the heart lobes end up lopsided.
- Sealing the seam before stuffing Add stuffing while a gap is still open in the joining round, then finish closing it with the needle.

Finish
- Weave in loose ends from the magic ring closures and any color changes before joining the halves.
- Add stuffing to the heart shape before the final stitches of the joining seam are closed off.
- Use a needle to close the small gap left between the two halves for a smooth, seamless edge.
Bigger or smaller
- Smaller
- Stay with a fine hook and thin yarn, or work fewer rounds of the main pattern before joining, to keep the heart compact and charm-sized.

FAQs
Asked and answered
These answers came from whoever first published the pattern, kept word for word.
What yarn weight suits this pattern best?
The pattern works well with most yarn types, so the choice comes down to how tight or plump the final heart should look. A finer yarn with the 1 mm hook keeps stitches dense enough to hold the stuffing in.
How is the keychain hardware attached?
Once the two halves are joined and stuffed, a keyring or clasp can be looped through the top stitches or a short chain added at the join. Secure it with the same yarn tail used to close the seam.
Does the heart really need stuffing?
Stuffing is what gives the piece its puffy shape, so it should go in before the joining seam closes completely. Skipping it leaves the heart flat instead of rounded.
