Kuba textiles are unique in the Democratic Republic of the Congo, formerly Zaire, for their elaboration and complexity of design and surface decoration. Most textiles are a variation on rectangular or square pieces of woven palm leaf fiber enhanced by geometric designs executed in linear embroidery and other stitches.

In Kuba culture, men are responsible for raffia palm cultivation and the weaving of raffia cloth. Several types of raffia cloth are produced for different purposes, the most common form of which is a plain woven cloth that is used as the foundation for decorated textile production. Men produce the cloth on inclined, single-heddle looms and then use it to make their clothing and to supply foundation cloth to female members of their clan section. The cloth is coarse when it is first cut from the loom, so it is then pounded in a mortar, which softens it and renders it ready for the application of surface decoration, for which women are responsible.

Many prestige weavings are dyed with twool, a deep red substance obtained from the heartwood of the tropical trees Pterocarpus sp. and Baphia pubescens. The Kuba believe that twool is imbued with magical and protective properties. When mixed with palm oil, it creates a pomade that is applied to the face, hair and body in a ritual context. According to oral tradition, the Pende were responsible for teaching the Kuba how to weave textiles; the Pende used twool to die their prestige clothes for death rituals.
