Since 2011, CYK has been organising  Natural Dye Trial program for promoting natural dye technique to the visitors who are interested in natural colors. In  March,　there are two groups of  visitors of  natural dye trial. On 6 March, three visitors from Germany and Japan came to attend  natural dye trial at CYK’s weaving Training Center in Trapeang Krosaing Weaving Training Center where CYK trains village weavers. All visitors were very interested in this tie-dye practice of silk scarf with dye liquid made by leaves of Indian Almond tree. This natural dye material produced beautiful yellow-green color. They enjoyed tying their own favorite patterns then they tried to dye their silk scarves by themselves.
