Do not use bleach (bleaching may weaken fabric and cause yellowing). Do not use fabric softener. Wash dark colors separately. To minimize shrinkage, tumble dry on low heat. Artisan information: The story of SFERRA begins in 1891, when founder Gennaro Sferra arrived in America from Italy with a passion for exquisite textiles, quickly earning a devoted following among the Gilded Age's most discerning tastemakers. More than 130 years later, that commitment to craftsmanship remains at the heart of everything SFERRA creates. From percale sheets woven in Italian family-owned mills to plush towels crafted from long-staple combed cotton in Portugal, each piece is made with meticulous attention to material, construction, and detail. SFERRA linens have graced the Vatican, the White House, and the world's finest hotels — and now, they're available at Home for Entertaining, bringing that same standard of timeless luxury into your home.
