I had a plan to make a tutorial for the "How to read crochet charts" series and feature a heart pattern, just before Valentine's, but the chart I decided on was so unintelligible I decided to alter the pattern, and just write the pattern down.
With your hook and choice of yarn / thread (I used 1.9 mm hook, sport yarn) Chain 8 and join to make ring
Inside the ring, chain 3 (counts as the 1st dc) and dc 3 more. "Chain 2 and dc 4". Repeat from "to" 2 times. You end the round by chaining 2 and sl st into the 1st chain of the round.
This is a bit tricky - in that 2-chain you just made, chain 3 and dc 3. "Chain 3, skip the crochet part (the 4dcs below) and in the chain space dc4, chain 2 and dc4 more" (all in that chain space). Repeat the "pattern" to make a full round. To end the round dc 4, ch2 and join with the beginning dcs with a sl st.
Rows 1+2: we'll be working on making the upper sides of the heart.
Without cutting the yarn, chain 2 to bring the yarn closer to the 3-chain space. In the 3-chain space dc14, then chain 1, turn work and sc in all the 14 stitches across. Sc across the middle (center part) and when you come to the 3-chain (on the other side) fill it.
That means dc14, ch 1,turn work and sc in all the 14 stitches across. Cut the yarn and tie / weave the end.
Making the border: insert new color in the center part / middle of the heart
Round 3: dc in every stitch around. To end, join with the 1st dc with a sl st. Cut yarn.
Round 4: picot round
Insert the yarn at the left upper side of the heart.
Ch 4, make a picot, skip 1, sl st in next. Repeat this pattern to fill the heart and its right upper side. And that's it.
I hope you enjoy making this lovely heart. You can use it as an ornament, a doily, as applique, make a bunting or whatever you can think of.
If you are curious about the unfortunate chart you can see it here.
Later tonight you can get this as a step-by-step tutorial attached as a gift pattern to this heart bunting.
