The technique of looping continuous lengths of plant fibre string is commonly used by women across the Highlands of Papua New Guinea for the production of string bags, or 'bilum', however it is also used to create long aprons worn by men on important ceremonial occasions. Looped plant fibre string caps are also produced by women and worn by both men and women for warmth and protection, with the fur of animals such as cuscus and tree kangaroo incorporated into the plant fibre string. This cap has delicate tufts of animal fur spun throughout the fibres.
