This is usually called Biaxial or +-45 Biaxial by our north american friends. We think double bias is a much clearer name for this cloth. This cloth is 1.27m wide and 0.58mm thick. It would have to be folded to go through the post, although it can be delivered on aroll by Fastway or a freight company. A full roll is 65 metres long.
