XF is derived from the folding technique ‘X-Form’. As the name suggests, the X-shape consists of a repeating pattern of triangles that resemble successive X’. For example, if you fold a ‘Heaven & Hell’, also known as ‘Salt & Pepper’, you get edges called ‘Valley’ and ‘Mountain’ folds in paper folding.
Unfolded, the result is a grid consisting of three horizontal, three vertical, three 90°, and three 180° diagonals. These lines form exactly 32 right triangles. In this way, flexible design grids are created through duplication or combination, which, transferred to 3D objects, take on a dynamic of their own.
Today we find the X-Form in paper folding, of course, but also in sculpture, architecture, graphic design, and installations. One artist, who creates metal, paper, and wood sculptures using folding techniques, is Peter Millett
