These are techniques that were originally used for fiber-related crafts (crafts using yarn & cord). They can also be adapted for craft wire in many cases. Macrame is the well-known art of combining different types of knots to create a fabric, often also used for wallhangings and other home decor when it's on a larger scale. Kumihimo is the ancient Japanese art of braiding. Here, both of these skills are adapted to jewelry making.
