A method for vibration or orbital welding of a fabric (2) to a thermoplastic substrate (4) includes forming an assembly which has a decorative outer face without markings or pin dents that need to be removed or brushed out. The fabric can be woven or non-woven material and usually is characterized by high (6) and low (8) density regions that are bonded to a thermoplastic substrate (4) in a vibration welder (15) having a smooth surfaced platen applying pressure to the exposed surface of the fabric. High quality bonds or vibration welds are obtained between a fabric and a thermoplastic substrate characterized by a textured surface (56) having tiny raised regions (58).
