Cold dyeing process is done in a typical manner using earthen pots with natural color materials. Cold dyeing area is set permanently. More than half part of earthen part is buried and remaining part is kept open. The basement of clay pot is covered with goat dung to maintain the temperature.
For dyeing indigo blue, Madharangi soppu- leaves of Madharangi plant are dried for one week. Then the dried leaves are soaked in water. These leaves are kept in a mould to make solid cake. The cake is placed in buried pot. Now the other extracted solutions like filtered Soudu mannu (sand) solution, Chatte Bija-seeds solution which is extracted by boiling Chatte Bija seeds and limestone water are added to the pot. Bleached cotton bundle is dipped in blue color and kept for one hour for the better color application. Colored cotton is initially dried for two days and again washed in cold water to make the threads soft.
Red color is obtained by adding Adike-beetel nut, Soudu mannu (sand) solution and limestone water.
