Duvet covers are always equipped with a closure mechanism, such as buttons or zippers. Some are available with various ornamental decorations that add elegance and texture to them, such as embroidery, ribbons, or buttons, while others are plain. Duvet covers with pleats, ruching, and flocking are examples of various decorations that may be seen on high-quality bedding. Similarly, pleating is a form of fold that is created by folding fabric over itself while ruching is a procedure created by gathering little ripples in the fabric together. Flocking is the deposit of microscopic particles on the surface of a cloth.
