due to the fibers and nature by which these are made the fabric and dyes may have minor imperfections or variation in color. i believe this makes each piece more its own and shows the human element coming into play.
i recommend hand washing or washing on delicate cycle cold water with an eco detergent and hang to dry in a shady spot. with natural dyeing, colors will fade if left in the sun, and some dyes may react to citrus (check natural deodorants for this to avoid discoloration). iron inside out with a hot iron when lightly damp.
