Stack up the hearts and place them in an envelope with the top end of the string showing so your recipient can pull the string and watch the hearts unfold out of the envelope. You can even decorate your envelope to match!
I used the darling Head Over Heels collection from Echo Park Paper Co. I love the soft pink, bold red, cool aqua, and grounding grey in this collection. And the artwork is adorable too--love the typewriters, arrows, hand scribbling, and darling tandem bike. For full supplies for this project, visit the Echo Park blog HERE.
