Coyuchi slub linen is loomed in a chunky cross weave that adds subtle detail to any bed and becomes softer with every wash. Woven with yarn-dyed stripes, each sham is finished with coconut shell buttons. All of Coyuchi's cotton and linen products are machine washable. For whites and light colors: Coyuchi recommends machine washing on a gentle or delicate cycle with warm water and non-phosphate soap. For dark colors: Coyuchi recommends machine washing on gentle or delicate cycle with cold water and non-phosphate soap. Line dry or tumble dry low and remove promptly. Use a warm iron on cotton or a hot iron on linen, as needed. Coyuchi does not recommend using whiteners as bleaching agents may diminish the brilliance and depth of the colors; when needed, use only non-chlorine bleach. Please refer to the product tag for more specific instructions.
