Basic folds of origami

The different folds used to achieve an origami are not infinite. These folds have been listed and have often been classified in three level of difficulty. As the symbols, the basic folds of the origami must be known well to facilitate the reading of a diagram (description of an implementation of origami). In this page we present you these different folds of bases in ascending order of difficulty.

Simple folds

The fold valley is a fold in hollow :
or

The fold mountain is a fold in crest, it is the contrary of the fold valley :
or

The zig-zag fold is a fanfold form :
or

The repeated fold is a fold that one redoes precisely :

Folds of intermediate level

The fold reversed interior is a fold inside a crest :
or

The fold reversed external is a fold contrary to a crest :
or

The complex folds

The fold doubles ear of rabbit consists to make a double ear of rabbit inside a crest :

The fold pivot and as called rotating fold :

The fold pressed opened begins the basis of the water bomb. One marks by a fold on the length (1). One opens the paper while pressing the top (2) to get a sort of small table (3) then one redoes the basis of the bomb to water while keeping the pike below :

The fold pressed closed begins as the pressed fold opened but while only opening a flank (the other rest pasted to the two interior folds). One folds back the pike thus of quoted it of the open flank. Of this manner pointed it blocks the two interior folds :

The fold envelops consists to envelop a part of the origami. The first line presents a fold envelops by before and the second line a fold envelops by behind :
