Paper Grain in Origami - Origami by Michał Kosmulski

Paper is made from plant fibers. When hand-made paper is laid using a sieve, a single sheet is produced at a time. Manual movements of the sieve cause the fibers to become arranged in a roughly uniform manner in all directions. In contrast, machine-made paper is produced as a long, continuous band which moves on a kind of assembly line between different productions stages. This causes the fibers to prefer an arrangement parallel to the movement, resulting in paper grain, also called machine direction: the paper’s properties differ between the machine direction (MD) and the perpendicular direction (sometimes called cross direction, CD). One can also say the paper is anisotropic.

Thank you for this wonderful article. I’ve never done more than simple origami myself, but I fully appreciate the depth of expertise required for a post like this.
