Sonic Fabric is woven from 50% polyester thread and 50% pre-recorded 1/8" audio cassette tape. It has the texture and strength of a light canvas, with an "elegant, mysterious metallic lustre." Come play with me.

From their site ... Although it was originally created solely for use in my own works of conceptual art, Sonic Fabric has found its way into very practical and functional applications in fashion, accessory, and interior design.
