Add patterns of colour to a fabric (3-3)

I believe the answer is:

tie-dye

(Other definitions for tie-dye that I've seen before include "Method of colouring garment in which it is knotted" , "Colour (cloth) in a particular way" , "Stain by knotting fabric to produce an irregular pattern" , "Hand colour textiles" , "method of patterning textiles" .)

I've seen this clue in The Guardian.
