In silk weaving, there are two sets of silk threads. The threads set in a vertical position are called warp threadswhereas those in a horizontal position are called weft threads. Warp threads Warp threads are positioned and arranged in straight draw with 4,000 reeds / 1-meter wide fabric. They are divided into 2 parts i.e. 2,000 reeds per each. The weaver uses a heddle and a pedal to separate silk levels by switching up and down Weft threads Weft threads are in the shuttle. The weaver pull the tugging rope attached to the weaving loom in order for the shuttle to pull the threads across left and right. The number of silk threads in the shuttle can be control to determine the level of fabric thickness as the silk fabric is called 1-ply, 2-ply and 4-ply silk. One-ply silk has thin texture suitable for making shirt, blouses, neckties or scarves. Two-ply silk has medium thick texture suitable for making dresses, skirts or trousers. Four-ply silk has thick texture suitable for making suits or jackets.
