A weave of linen and cotton, yarn dyed in slightly different hues, lends the Coyuchi sham nuanced color. Bordered with stitched stripes that cross at the corners, it's self-backed and finished with coconut shell buttons at the envelope closure. 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.
