Fixing damaged cashmere depends on how bad it is. You can sew up small holes and snags from the inside, gently remove pills with a cashmere comb, treat stains carefully, reshape stretched cashmere in cold water, and remove wrinkles with steam. If it's smelly, air it out or use a fabric spray. For serious damage, get help from a professional tailor or cleaner experienced with cashmere. Always handle cashmere gently, follow care instructions, and store it folded in a safe place away from moths, sunlight, and rough surfaces to keep it looking good.
