One of the oldest examples of yarn arts is the technique of "nalbinding"-- similar to crochet in that you make a knot in each stitch. Below you can see an example of nalbinding from from 300 CE in ancient Egypt. In sub-Saharan Africa, a similar technique was used by knotting fibers of the raffia palm tree. So ancient and widespread is the technique that there are over a thousand known stitches, allowing a person to create everything from stiff to stretchy materials. In many places, nalbinding was replaced by mechanical looms to save time. But time-consuming activities are worth it if they can make patterns so intricate that it brings prestige. An intricately knotted hat worn by a member of the royal court in Central Africa, like the one below, shows that you are worthy of the weaver's best work.
