Scorefold

Scorefold is a term that can refer to a few related concepts, primarily within the fields of origami and papercraft. In its most common usage, it describes a specific type of fold in origami where a crease is made across a section of paper, and then that creased section is folded again. This results in a layered or "folded-over" effect. Think of it as creating a small hem or a reinforced edge through repeated folding. The purpose of a scorefold can vary; it might be to add structural integrity to a specific part of a model, to create a visual detail, or to prepare a section for a subsequent, more complex fold. The term is sometimes used interchangeably with "pleat" or "double fold," though the precise definition can depend on the context of the specific origami instruction or project. It's a fundamental technique used in many paper folding designs to achieve desired shapes and forms.
