The idea of tapestry weaving in the early part of the Middle Ages was to tell a story. Few colors were used, and instead of making one large picture, which would have been very difficult with the looms then in use, the tapestries were made in sets, in which a series of pictures from some legends or chronicle could be shown. When in place, they were wall-coverings hung loosely from great iron hooks over which rings were slipped, or hangings for state beds, or sometimes a strip of tapestry was hung above the carved choir-stalls of a church, horizontally, to add a touch of color to the gray walls. When a court moved, or there was a festival day in the church, these woven or embroidered hangings could be taken from one place to another. Many tapestries were embroidered by hand, which was easier for the ordinary woman than weaving a picture, but took far more time. Kings and noblemen who had money to spend on such things would order sets of tapestry woven by such skilled workmen as Cornelys Bat and his Flemings, or the monks of Saumur in France, or the weavers of Poitiers. In Sicily, these hangings were often made of silk, for silk was already made there. Gold and silver thread was used sometimes, both in weaving and embroidery. Wool, however, was very satisfactory, not only because it was less costly than silk, but because it took dye well and made a web of rich soft colors. It was this which had drawn Robert Edrupt into Flanders to see what the weavers there were about, what sort of wool they used, and what the outlook was for their work. In Cornelys Bat he had found a man who could tell him very nearly all that there was to know about weaving. Yet weaving is a craft of so many possibilities and complexities that a man may spend his whole life at it and still feel himself only a learner. The master weaver liked Cimarron because the boy never chattered, but kept his whole mind on his work. When Cornelys was revolving some new combination or design in his head, his drawboy was as silent as the weaver's beam, and the whirr and clack of the loom were the only sounds in the place.
