The long-staple fibers of organic American Supima cotton lend silky smoothness to our sham's delicate jacquard-woven Dots. Only fabrics made from 100% American Pima cotton-among the world's finest cottons-can use the brand name Supima , and only 1% of all American Supima is certified organic. Ours is processed and finished as cleanly as it's grown, earning it GOTS certification as well. Finished with a knife edge, 2 inch flange and an envelope closure.
