Waldorf dolls by Kathe Kruse and Silke are individually handcrafted and not massproduced. They are made of natural materials such as sheep wool and cotton stockinette. The waldorf dolls appearance is intentionally simple in order to allow the child playing with it to improve or strengthen imagination and creativity. For example, the waldorf doll usually has a neutral expression so a child can imagine the doll laughing, crying, sleeping and being happy or sad.
