Heart Corner

Start with a square sheet of paper: fold it in half (left to right) and unfold. Fold it in half (top to bottom) and unfold. If you are using origami paper, start with the white-side facing up.

Turn the paper over.

Fold the paper along the diagonals in both directions; unfold. This gives you a “X” shaped crease superimposed on the “+” crease made above.

Bring the top-edge of the paper to meet with the bottom-edge of the paper. At the same time, push in the left and right sides.

In transition… the paper will naturally fold along the creases you’ve already made. When done, the triangular shape is called a waterbomb base.

Fold the top of the waterbomb base down so it meets the bottom of the paper.

Unfold.

Fold up the top layer of paper. Use the crease made in step 4 as a guide.

In transition.

Make valley folds so the corners of the waterbomb base fold up and meet at the top of the peak.

Fold the front structure down.

Fold the bottom edge of the structure halfway up.

Peel down the top-most layer of paper.

Squash down the left and right sides of the paper so it becomes flat.

Fold up the small flaps as shown.

To make the heart more rounded, fold up the pointy corners.

Finally, fold the structure back up so it looks like a heart.

Done!
