Chris Aslan tells his story of working with UNESCO to establish a silk carpet workshop in the desert oasis of Khiva, Uzbekistan - the most homogenous example of Islamic architecture in the world.  His work took him to the bazaars of Afghanistan to purchase natural dyes, and to the great libraries and museums of Europe to track down 15th century manuscripts to revive carpet designs from their illuminations.  He also saw the lives of women transformed and became the largest private employer in town.
