Abstract
An item such as a fabric-based item may have a layer of fabric with openings that are illuminated by a light source. The openings may form symbols or other shapes and may serve as labels for keyboard keys or other components. The fabric may be formed from transparent strands of material that are coated with opaque material or may be formed from opaque strands of material in which openings are formed by laser drilling. The openings may be covered with a transparent coating layer such as a translucent polymer coating. Translucent material on the fabric may be patterned to form parts of the labels or other shapes created by the illuminated openings.
