pleating

Pleating is a fabric design technique that involves creating a pattern of creases in cloth. These creases can be made in various styles, such as accordion, side, box, or sunburst pleats.1

Pleating can be achieved through two primary methods:
* Machine Pleating: Specialized machines use blades or rotary surfaces to press creases into the fabric as it passes between heated rollers.1
* Pattern Pleating: Fabric is sandwiched between interlocking paper patterns that shape it into the desired pleat design. This trio is then steamed to set the creases.1

The term "pleat" can also refer to the fold itself, which is made by doubling the material over on itself. Historically, pleating has roots in Middle English and Latin, relating to the concept of folding or bending.2
