Split Ply Weaving
From AmtWiki
Ply-splitting is a generic term that includes ply-split braiding and the much more common ply-split darning. The difference: in ply-split braiding, there is one set of elements (cords), and each cord moves at an angle to the selvedge; in ply-split darning, there are two sets of elements, with cords at right angles (comparable to warp and weft in weaving).
Ply-splitting can be flat, but it can also zig-zag and spiral, and in fact can take just about any three-dimensional shape. A vast number of geometric and pictorial designs are also possible. This is exciting and mostly unexplored territory. There are designs for making, instructions for ornaments, necklaces, bags, baskets.
