 According to the reference found in Kautilya's Economics about various productions and exports from Nepal, during the time of Chandra Gupta Mouriya, in fourth century, Nepal was known for quality rainproof woollen blankets.The blankets were made of eight pieces joined together of black colour known as "bhiringisi" as well as "apasaraka".Similarly the good quality blankets are mentioned in the epics of Jain religion "Brihatakalpasutra Vhashya".
