A fiber optic fabric includes woven optical fibers, an opaque coating on the fibers and openings on the high points of the weave. The opaque coating prevents light leakage from the fibers and the openings allow light to be emitted from the fabric in a directed manner. The fabric is capable of emitting light at an angle relative to the surface of the fabric such that the light is not visible from every viewpoint.
