Care instructions: Wash Cool - whether you wash in a machine on gentle-cycle or in basin, use cool water, this prevents any shrinkage in the fabric. Hang Dry - air dry on a hanger or clothesline, avoid machine drying if at all possible. Not only does this use less energy but it keeps the integrity of the fibers intact for years to come. Iron - iron with steam as needed.
