Is the woof the same color on both the front and back?

Right. It is also because of the weaving method that determines another characteristic of woof - the finished product with the excess threads trimmed off the reverse side has exactly the same pattern and color on both sides.

Woof is not really carved with a knife, it is a kind of raw silk for the warp, colorful cooked silk for the weft, the use of through the warp back to the weaving method of plain fabric. As we all know, there are warp and weft lines on a map, the vertical lines are the warp and the horizontal lines are the weft. To explain it in layman's terms, the vertical rows of dense silk are used as the warp threads, and then the horizontal rows of colored silk threads are used as the weft threads.

The colorful weft threads are arranged horizontally as the weft threads, which means that the colorful "warp threads" are woven on the silk "weft threads". Unlike embroidery, which uses needles and threads to embroider designs on various fabrics, woofing uses colored threads to weave patterns on silk.

The most obvious characteristics of woof: the first is the unique process called "through the warp and break the weft", and the use of tools is also a special tool. The second point is that it can give people a sense of "bearing the air carved", and the front and back of the woof work is the same appearance, there will be no threads appear. The third point is that the process is complex, the time required is long.

According to scholarly research, as early as two thousand five hundred years ago in the park before the appearance of the woof products, but only from the historical record in the conclusion, because the organic matter is very easy to rot, so there has been no excavation of the physical.
