Then they dunk it in mud😯
Why? To soften the fabric.
Here's how they do it👇
First, small round stones are tied in different spots on a white piece of cotton fabric🔰
The tied fabric is soaked in water and then dunked in the filtered dye created from the Ka Long tree barks boiled for 4 hours🔰
After half an hour the dyed fabric is then removed, cooled down and then dunked in the muddy solution to soften the fabric🔰
Finally the stones are removed and you get to see the designs on the fabric. Then it is rinsed with ash water. "Color stay better and becomes tough," says the lady explaining the ash water🔰
