Geometric Origami is a book on the mathematics of paper folding, focusing on the ability to simulate and extend classical straightedge and compass constructions using origami. It was written by Austrian mathematician Robert Geretschläger [ de ] and published by Arbelos Publishing (Shipley, UK) in 2008.
Modular origami or unit origami is a multi-stage paper folding technique in which several, or sometimes many, sheets of paper are first folded into individual modules or units and then assembled into an integrated flat shape or three-dimensional structure, usually by inserting flaps into pockets created by the folding process.

Stencils are also used in micro- and nanotechnology, as miniature shadow masks through which material can be deposited, etched or ions implanted onto a substrate. These stencils are usually made out of thin (100-500 nm) low-stress Silicon nitride (SiN) in which apertures are defined by various lithographic techniques (e. g. electron beam ...

Wet-folders usually employ thicker paper than what would usually be used for normal origami, to ensure that the paper does not tear. [1] One of the most prominent users of the wet-folding technique is Éric Joisel, who specialized in origami animals, humans, and legendary creatures. He also created origami masks.
In 1893, Indian civil servant T. Sundara Row published Geometric Exercises in Paper Folding which used paper folding to demonstrate proofs of geometrical constructions. This work was inspired by the use of origami in the kindergarten system. Row demonstrated an approximate trisection of angles and implied construction of a cube root was impossible.

In the 1850s, during the Victorian era prior to Morris, most English wallpaper was inspired by the geometric and historical designs of Augustus Welby Pugin, who had created the neo-Gothic interiors of Westminster Palace, and Owen Jones, notable for his abstract geometric patterns.
