Thousands of multi-coloured sheets of cotton are delicately laid out to dry under the blazing heat. The patchwork of purple, pink, blue and orange stretches towards the horizon after workers unfold hundreds of metres of freshly-dyed cloth. The field, in Narayanganj, Bangladesh, is packed with the bright sheets which will be used to create traditional women's dresses. Cotton cloths ready for dyeing are plunged into water before wax is used to create stunning multi-coloured Batik patterns. Once dried, the vivid sheets of cotton are taken to a local wholesale market where buyers purchase in bulk ready for customers.
