Lance,
Cross-wraps are a phenomenon often misunderstood. Ray already described this in his post, but it bears repeating: when a second material overlaps the earlier material, and the
angle, the slant, of the wraps are different, this
is a 'cross-wrap'. It is not dependent on one slant being bottom left to top right, and the other bottom right to top left.
Translate this to a dubbed body, where for example there were a dozen turns of thread, and a ribbing, with say five turns of the material to cover the same distance - this results to all practical, as well as theoretical, intent in a cross-wrap.
Cheers,
Hans W
