Every symbol in Chinese textiles had significance, and evolved from several philosophies and concepts. The Chinese enjoy puns and plays on words, and often designs were used if their verbal sound or written character was similar to a quality or virtue. Hence, because the words for bat and happiness sound similar, bat became the symbol for happiness.
The invention of the draw loom and the development of jacquards and brocades allowed patterns to be woven into the cloth. Common patterns included checks, diamonds, zig-zags, coins, clouds, dragons, lions, horses, flowers, birds and fish. Brocades were often over-embroidered to augment the woven patterns (a technique I now employ on my hats…)
