The Cork Store sells–you guessed it–cork stuff. Among their more interesting offerings is their cork fabric. It ‘utilizes the natural beauty and warmth of cork while allowing for the richness and durability of leather.’
The upholstery grade fabric–which is machine washable at 90 degrees Fahrenheit–is 1.5 yards wide and costs $130 per linear yard. Admittedly not the cheapest fabric available, but certainly one of the more interesting. It can be used in a variety of applications including making clothing and re-upholstering furniture.
