The Pattern Itself
Part 1: Make Two Heart Pieces
Round 1 (Heart Center)
- Magic Circle: Begin with a magic ring.
- Ch 1 to secure the ring, then ch 1 more (acts as 1st chain-space).
- Work 8 puff stitches (3yo) into the MR—after each puff, ch 2 before the next puff.
- (Each puff = [yo, insert in ring, yo, pull up loop] x3 for 7 loops, yo, pull through all, ch 2)
- Join with sl st to top of first puff to close the round.
Quick tip: Work 8 puffs separated by “ch 2” into a magic ring, then close with a slip stitch.**
Round 2 (Heart Shaping: Top Curve & Sides)
- Setup: Sl st into next ch-1 sp, then next ch-2 sp.
- Top Curve: In this ch-2 space:
- Work 5 puff st (3yo), with ch-1 between each puff (creates a domed curve at the heart’s top).
- Right Side: Into the next two ch-2 spaces:
- Work 1 puff st (4yo), ch 1 (repeat twice, one for each space).
- Bottom Point: Into next ch-2 space:
- Work 2 puff st (3yo), ch 1, ch 2, 2 puff st (3yo) (all in same space; forms the heart’s lower tip).
- Left Side: Into the next two ch-2 spaces:
- Work 1 puff st (4yo), ch 1 (repeat twice).
- Top Curve (final curve): Into last ch-2 space:
- Work 5 puff st (3yo), ch 1 after each except last.
- Joining: Insert hook into the starting magic circle, pull up a loop through to the front, sl st to close and give heart its shape.
For the heart shape, work 5 puffs on each top curve, longer puffs on the sides, and extra puffs/chains at the bottom tip for a point.
Part 2: Make a Second Heart
- Repeat Rounds 1 and 2 exactly as above to create a matching heart motif.
Just make a second heart piece exactly the same as the first one so you have two.
Assembly & Finishing
- Joining: Hold both hearts back-to-back, lining up the curves and points.
- Attach yarn at any top curve ch-1 space through both layers.
- Work 1 sl st and 1 ch-1 into each space/side through both layers all the way around, joining pieces together firmly.
- At the bottom tip: Work only 2 sl st and 2 ch-1 into the pointed end for a smooth join.
- Finishing: After completing the round, join with sl st to starting point. Do not cut yarn yet.
- Keyring Chain: Ch 30 to form the loop, sl st back to heart to make a hanging loop, fasten off, and weave in all ends securely.
- Attach hardware: Thread chain loop through your keyring or lobster clasp.
Hold both hearts together and slip stitch/ch-1 all around. Chain 30 at the top before fastening off to make a loop for your keyring.
Assembly & Finishing
Secure all ends: After closing, use the yarn needle to hide and secure ends firmly inside the piece.
Insert keyring: Slide the keyring or clasp through your 30-chain loop to finish.
Optional:
- Add a dab of fiberfill before final stitches if a puffy heart is desired.
- Embroider a name or initials for personalization.
