How To Make Custom Conversation Hearts In Four Steps

I have a soft spot for conversation hearts. I don’t even like eating the candy, but the fact that these cute, adorable hearts with typography on them exist in the world makes me happy.

They are so little and so precious that I can’t help but buy a package just to hold them and read the messages.

It was this obsession with the scale of the candy that caused me to make my own little miniature conversation hearts. It also meant that I could control the colors and give the messages my own voice by adding a pop culture linguistic upgrade.

Oh, and did I mention that they’ll last forever? In just four steps, you too can make your very own original conversation hearts.

Trust me, it’s fun!
