Tibetan carpet making is an ancient, traditional craft. Tibetan rugs are traditionally made from Tibetan highland sheep's wool, called changpel.  The carpet-making industry in Tibet stretches back hundreds if not thousands of years, yet as a lowly craft, it was not mentioned in early writings, aside from occasional references to the rugs owned by prominent religious figures. This Dragon pattern hand knotted rugs took one month to get ready . So buy Tibetan rugs which is made by Tibetan refugee people. Thank you
