Peter Collingwood introduces ply-split braiding, a technique in which one cord is split through its plies to let another pass through, used in northwest India for camel girths and bags. The article explains how to make four-ply cords with a power drill, how to mount them on a starting rod, and how to work plain oblique twining (short and long rows with a quarter twist between splittings). It also covers color patterning with twined linkings, slits, cylindrical and 3-D forms, and turning a braid through a right angle, and mentions two further structures to be covered in later articles.
