Disclosed is a method for applying light diffracting materials to a fabric in a selective pattern and which allows the fabric to withstand repeated laundering without significant deterioration of the light diffracting image. A base of adhesive resin with a layer of flexible material thereabove is adhered to the fabric in the desired selective pattern. A layer of light diffracting material is then bonded to the flexible material. The adhesive resin infiltrates the fabric and, when cured, the resin secures the fibers of the fabric in a controlled shape to prevent the fibers thereat from shifting relative to one another, thus substantially eliminating stretching and shearing forces in the layer of light diffracting material adhered thereto, which forces are commonly encountered during laundering. The resin base and flexible material layer also serve to prevent the layer of light diffracting material from sinking into the fabric during laundering, thus providing still further improvement to the launderability of the light diffracting product. In one embodiment, a light diffracting iron-on sheet is provided by which a predetermined light diffracting image may be applied to the fabric by a conventional iron. In still a further embodiment, an iron-on sheet is provided which allows for application of a light diffracting image to fabric in any desired selective pattern by applying heat and pressure to the iron-on sheet over only selective portions.
