Start with a square sheet of paper, colored side down
Fold the paper in half diagonally to make a triangle
Unfold, then fold the other diagonal and unfold again
Fold the top corner down to the center point
Fold the bottom corner up to meet the top edge
Fold the left and right corners inward toward the center line
Fold the top two side edges slightly outward to round the heart shape
Fold the bottom point upward to form the heart’s dip
Flip the paper over
Adjust the edges and creases to shape the heart neatly
