The desire for decoration led to the changes in weaving technique already mentioned. The employment of flaxen tags to form a thatch for rain capes page 305and rain cloaks was stimulated by the necessity for protection against the weather but the application of coloured cords, pompoms, and feathers was definitely decorative in purpose. The introduction of one coloured element in the single-pair weft used in me close single-pair twining of the borders of dogskin cloaks formed the starting point for further development in the use of colour (Fig. 32a). Toachieve wider bands of colour, a change in technique was required and this was accomplished by using full turns instead of half turns as already described (Fig. 32b).Thus the technique advanced from single-pair twining with half turns to the wrapped or birdcage twine with full turns. The wrapped twine with two colours in turn formed the basis for the development of a technique whereby more than two colours were introduced by means of a composite weft containing the additional colours (Fig. 33a-c).The composite wrapped twine made possible the production of geometrical figures in various colours in the wide bands termed taniko. See Figure 88. In plaiting, the introduction of colour for decorative purposes did not effect any fundamental changes in technique but in weaving, actual changes in technical processes were evolved for the sole purpose of obtaining greater artistic expression in coloured designs.
