A simple kosa saree takes around five days to produce from yarn extraction to the weaving, depending on the number of craftsmen working on it. Its natural dull gold colour is often dyed to get earthen tones. Natural dyes used for prints include yellow from the palaas(the Kusum) Flower, the rich red pollen dust of the Rora Flower and the deep rose-red from Lac, and more.

Each cocoon woven by the kosa silkworm yields 1-2 grams of raw silk yarn, equivalent to about 300 yards of thread. Due to the rarity of the kosa worm and the laborious cost of cultivating it, the raw silk yarn is often blended with cotton or polyester.

Heavier the Saree, longer it will last. The best way to check purity of silk is to burn a few threads of it. Not to be confused with ash, it will coagulate and leave an unpleasant smelling black powdery residue.
