Forget piano key neckties. If you really want to wear something different at your next black tie event get one of these Sonic Fabric Neckties. Sonic fabric is a textile woven from 50% recorded audio cassette tape and 50% colored polyester thread. That’s right…audio cassette tape. This unique fabric is the creation of Alyce Santoro and the ties are hand sewn by Julio Cesar. Buy a Sonic Fabric Necktie (or just learn more about it) at Supermarket.
