In general, the Chincha weavings are smooth and closely woven (pls.
3,b, and 4,b). There appears to have been little or no interest in
varying the textures by employing yarns of different weights, although
the usual irregularities to be noted in lengths of hand-spun yarns
are also evident in these. Counts taken on the warps and wefts per
inch give a fair indication of the textures, but these are to a degree
dependent upon the spinning.

Figures indicate number of specimens. Symbols: triangle, apex down,
unit consists of one warp and one weft element; open square, unit
consists of one warp, two weft elements; concentric circles, unit
consists of two warps, one weft element; triangle, apex up, unit
consists of warp and weft pairs.]
Several variations of the elemental over-one-under-one plain weave are
exemplified by the Chincha cloths. Included are the following:
combinations of pairs of warps or wefts with single yarns of the
opposite system, and pairs of warps and wefts as in the two-by-two
basket weave. The one hundred and twelve specimens represented in the
scatter diagram (fig. 5) fall into groups, according to the variations
of the plain weave these are listed below in the order of their
frequency:
