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 176 images, including models, this book illustrates the versatility of plain oblique twining, a version of ply-split braiding particularly well-suited for the art of basketry, in making three-dimensional sculpture. This guide to one artist's creative process shows how a ply-split braided basket is shaped, based on the rate and location of adding and removing cords. Chapters include creating fenestrations, substituting cords, combining baskets, crossing planes, and harnessing the tension between right triangles when the hypotenuse of one aligns with the leg of another.
