Twining is one of the earliest methods of basket making. Twining styles, materials and decorative motifs vary by region. The burden basket style is common among many cultures in North America. The kit comes packed in a plastic bag that can be used to store materials while you make your basket. Baskets are woven containers. They are extremely important to human existence because they allow for the storage of food and carrying of resources. Humans worldwide have used native materials to craft baskets to aid in daily tasks and requirements. In addition to utilitarian basketry, decorative basketry is also important for artistic expressions of individuality, spirituality and tribalism. Archaeologists and historians have learned much about ancient cultures from basketry fragments which have been found across the globe. Basketry continues on as an important human activity.
