| THE VALLEY FOLD |
 |
| The valley fold is formed by folding the paper towards oneself and is demonstrated with a dashed line. An arrow usually shows where to fold the piece of paper to. |
| THE MOUNTAIN FOLD |
 |
| The Mountain fold if formed by folding the paper away from oneself and is demonstrated with an alternating dashed and dotted line. |
| THE PETAL FOLD |
 |
| The petal fold lifts a point,corner or edge and brings it upwards to that the two edges of the point lie together. It serves as a means of narrowing a point, or forming a point from an edge. An incomplete petal fold is where the two edges do not meet. |
| THE SQUASH FOLD |
 |
| The squash fold takes a point and squashes it flat to become a flap. It is a way of converting one folded edge into two. It is best done by opening up the flap and flattening it so that the crease of the former edge lies on top of the fold line at the base of the flap. |
| THE REVERSE FOLD |
 |
| Also called a pocket fold or an inside reverse fold, this is a more fixing way of changing the direction of a flap rather than simply mountain or valley folding it. The edge of the flap is pushed through so that a mountain fold edge becomes a valley fold edge, and vice versa. It is easiest to precrease the fold with a mountain and a valley fold in its place first. |
