Abstract
A method of making three-dimensional simulated stained glass objects from resins. A sheet of resin having the ornamental pattern of the object printed on it is preformed substantially to the shape of the object. The preform is inserted in an injection mold for being reinforced on one side or another with a thicker resin layer. Mounting flanges, bosses, ribs, interlocking joints and other mating configurations are formed with the reinforcing layer to enable combining a molded three-dimensional section with other three-dimensional sections to form more complex objects. The printing on the flat resin sheet is pre-distorted, as required, so that when it is formed to the contours of the object the printing will assume a proper undistorted form.
