Ikat originated in Indonesia. It's a method of resist-dying threads before they are woven. Little pieces of plastic are wrapped around the weft threads. When the threads are dipped in dye, the color doesn't adhere to the portions covered in plastic. Then the weft is woven into the warp and a pattern is created.
I took the pictures below today at the Brunschwig & Fils showroom in the D&D Building. The fabric line pictured is B & Co.
