ABSTRACT:
A method for constructing a relief sculptured sound grill comprising the steps of soaking a strip of flexible material in a starch solution and thereafter securing the flexible material between a male and female mold member so that the mold members form the desired relief sculpture on the flexible material. The strip of material is then dried and paint is applied to the relief sculpture and dried thereby permanently forming the relief sculpture on the strip of material. A frame is then secured around the periphery of the strip of material and the mold members are removed so that a hardener may be applied to the entire strip of material. The strip of material with the attached frame is then dried thus completing the relief sculptured sound grill of the present invention.
