The Universal Language of Origami

Origami is made from a combination of mountain and valley folds. Here’s the
system Yoshizawa created, which was later adopted and changed slightly by
Western origami authors Samuel L. Randlett and Robert Harbin. The system
uses dashed and dotted lines and arrows. With a series of diagrams using these
symbols, a reader can learn how to make an origami sculpture. A fold pattern
shows a complete guideline for making origami in one diagram.
Types of folds
Origami consists of two kinds of folds:

mountain fold valley fold
The five types of lines used in origami diagrams

These are the five kinds of lines shown on an origami diagram:

raw edge
crease =
location of an
earlier fold, mountain fold =
since unfolded paper folded away
from you

valley fold =
paper folded
toward you

X-ray line =
hidden edge
or crease
