Pleating is a sewing technique that involves folding fabric into a series of regular, even folds. These folds can be stitched in place to create a structured design, adding texture and volume to garments or other fabric items. Pleats can vary in size and depth, and they are commonly used in skirts, dresses, and curtains. There are several types of pleats, including knife pleats, box pleats, and inverted pleats. Each type has a distinct appearance and serves different aesthetic or functional purposes. Pleating can enhance the fit of clothing and is often used in fashion design to create elegant silhouettes.
