|Rows of hand embroidery in ombre shifts of color edge Coyuchi's buttery organic cotton sateen. Twill woven to a 300-thread count, these sheets resist wrinkling and have a supple, soft hand. An elegant 7" attached hem finishes the flat sheet and pillowcases, which are designed to coordinate with Coyuchi's classic sateen fitted sheet. Our cotton is 100% organic. .
