Ply-split braiding is a technique for making textiles by parting the plies of one cord (the splittee) with a needle or similar tool, drawing a second cord (the splitter) through the gap made in the first cord, and repeating the process many times over. With images, including patterns, these techniques illustrate how to make baskets using plain oblique twining, a version of ply-split braiding particularly well-suited for the art of basketry.
