These are granny style hearts I worked up a few years ago to send to my daughters on Valentine’s Day. I’m not a designer, and had just begun to learn crochet, so the instructions may not be very professional. But I think it should work, once you get the idea.
I used Rowan Cotton and a 4.5 hook, but for creativity, I think anything would work!
I’ve added an updated pdf; hopefully that may work slightly better. It’s clear that I’m not a pattern designer, but I hope that these are still a bit fun to make!
