Turn colorful cupcake liners into Valentine’s Day pins and cards. Simply take colorful liners, flatten and cut to different sizes with pinking shears or scalloping scissors. Then, layer on top of one another on a construction paper card and glue down to adhere. Add ribbons, glitter, and use crayons, markers, etc to write the recipient’s name in the middle of the liner, a glitter heart, or even a conversation heart.
