Pattern Instructions
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.
Optional: Add a dab of fiberfill before final stitches if a puffy heart is desired. Embroider a name or initials for personalization.
Tips
- Work the puff stitches with consistent tension to ensure both heart pieces are the same size for a neat join.
- When joining the two hearts, take your time to line up the curves and points perfectly for a symmetrical final shape.
- Weave in ends securely, as the keychain will be handled frequently.
FAQs
Can I use a different yarn weight for this pattern?
Yes, you can use a different yarn weight, but your finished heart will be a different size. You may need to adjust your hook size accordingly to achieve a similar texture.
How do I make the heart keychain larger or smaller?
To change the size, you can use a thicker or thinner yarn with a corresponding hook. Alternatively, you can adjust the number of chains between puffs in Round 1, but this will change the overall shape.
Is the puff stitch difficult for a beginner?
The puff stitch is a bit more advanced than basic stitches, but it is easy to learn with practice. The pattern provides clear instructions, making it a great project for a confident beginner.
Can I make this keychain without a magic ring?
Yes, you can start with a chain-4 and join to form a ring, then work the puffs into the ring. However, the magic ring creates a tighter, more closed center.
How do I attach the keyring hardware?
After you have made the 30-chain loop at the top of the heart, simply slide your split ring or lobster clasp through the chain loop before weaving in the final ends.
Can I wash the finished keychain?
Yes, because it is made with 100% cotton yarn, you can hand wash the keychain in cool water and lay it flat to dry. Avoid machine washing to maintain its shape.
