The toaster cloth is made of fabric with metal wires interwoven. The metal wires can heat up to a substantial temperature, enough to toast bread.
The first slice of bread is placed on the cloth, wrapped once; the second slice is put on top and wrapped as well. Turn the Toaster on and there’s your toasted bread! However crazy the idea of a flexible toaster may seem, this material made it possible to combine “soft, fabric-like” behaviors with high temperate, a combination not often seen in consumer electronics.
