How to Fold an Origami Devilish Heart

This playful devilish heart —Cœur Diabolique— is another fun creation by Francesco Mancini. It’s folded from a triangle, which means you can make two hearts from one square sheet of paper.

The folding process starts with some precreasing and a 3×3 grid, which gives you a chance to slow down and focus on precision before folding the heart and its cute little horns.

It’s perfect for Halloween, Valentine’s Day, or anytime you want to mix sweetness with a bit of mischief. Try red and white paper for a classic look, or experiment with duo colored paper like in the photo.

Fold the bottom right corner to the pinch mark you just made. Crease all the way to the top, then unfold.

Repeat Step 9 on the top and bottom corners.
