Abstract: A method of making simulated stained glass from moldable plastic material. One wall of a die is formed with a series of interconnected recesses which border isolated areas, and the isolated areas of the die are provided with random surface indentations. A sheet of plastic film having a series of dark colored interconnected strips, corresponding in configuration to the recesses in the die, and having a series of light colored zones of the same configuration as the isolated areas of the die, is disposed on the die surface with the dark colored strips in precise registry with the recesses of the die and the light colored zones in registry with the isolated areas of the die. The plastic film is held against the die surface by a vacuum, and a liquid thermoplastic resin is injected into the die cavity.
