pleate

Pleate refers to a series of folds or wrinkles in a material, typically fabric or paper. These folds are often intentional and serve various purposes, such as creating decorative patterns, adding volume, or facilitating a specific function. The term can be used as both a noun and a verb.

As a noun, pleate describes the fold itself. For example, a skirt might have several pleates, referring to the individual sections of folded fabric. These pleates can be permanent, achieved through pressing and stitching, or temporary, formed by creasing.

As a verb, pleate means to create these folds. One might pleate a piece of fabric to make it appear fuller or to create a textured surface. The act of pleating involves folding the material over itself and securing it, often with stitches or heat.

The appearance and function of pleates vary widely depending on the material and the intended design. In clothing, pleats can range from sharp, tailored knife pleats to softer, more voluminous box pleats. In decorative arts, pleating can be used to create intricate patterns on paper, such as in origami or to produce fan-like structures. The precise nature of a pleate is determined by the width, depth, and spacing of the folds, as well as the material's flexibility and the method used to create and maintain the fold.
