A web-published monograph by Paul O'Connor on applying Alice Schlein's network drafting principles to double weave. It moves from a single-layer network drafting background through networked double weave designs (window and checkerboard) using tieups and peg plans on 8, 12 and 16 shafts, to designs built on blocks. It also covers integrated double weave, in which all threads lie in a single cloth layer, and symmetry rules such as extra threads at turning points. Appendices hold catalogs of 4x4 peg plans with their drawdowns (0 to 8 additional pegs) and a discussion of turning points in double weave.
