Which traditional Nigerian craft involves embossing leather for decoration?

Leather tooling is the traditional craft technique that involves creating decorative patterns and designs on leather through embossing, stamping, and incising. In Nigeria, leather tooling is particularly associated with the northern regions, where artisans have long produced elaborately decorated leather goods including bags, cushion covers, sandals, and poufs.

Batik is a textile dyeing technique that uses wax-resist methods to create patterns on fabric, not on leather. Weaving involves interlacing threads or fibres to produce cloth or mats. Pottery is the craft of shaping and firing clay into vessels, containers, and decorative objects. None of these crafts involves embossing leather for decoration.
