When you are studying an origami diagram, you will be encountered with line symbols such as dashed line or dot-dashed line.


A simple dashed line represents a valley-fold while a dot-dashed line for a mountain-fold.


Here I use the blue color for a mountain-fold and the red color for a valley-fold just for a convenience.

For an example, if a diagram shows a vertical dot-dashed line in the middle of the paper, it means you should mountain-fold along the line.

If you apply a mountain-fold to the dot-dashed line, the paper will be transformed to form a "mountain-shaped" figure.


The result is exactly opposite when you apply a valley-fold which produces a "valley-shaped" figure.
