Downfolded

Downfolded is a term used to describe a specific type of folding technique commonly employed in origami, the art of paper folding. In downfolded creases, the paper is folded downwards, creating a valley fold. This technique is fundamental in origami and is used to form the basic shapes and structures that are the foundation of more complex models.

The downfolded crease is achieved by aligning the edge of the paper with a reference point, typically a corner or a previously made crease, and then folding the paper downwards. This action creates a crease that runs perpendicular to the edge of the paper, forming a valley. The depth of the fold can be adjusted by how far the paper is folded downwards before being pressed flat.

Downfolded creases are essential in origami for several reasons. They allow for the creation of flat surfaces, which are necessary for the construction of various origami models. Additionally, downfolded creases can be used to create symmetrical shapes and structures, which are a hallmark of traditional origami designs. Mastering the downfolded crease is a crucial step for anyone learning origami, as it forms the basis for more advanced folding techniques.
