According to the passage, what is the most basic part of the saree making process that lends the saree its splendour?

Directions: Read the following short passage and answer the question. 

The silk industry in Kancheepuram is one of the fastest growing industries in India. The industry currently employs more than 30,000 weavers in the art of saree making. This was not the scenario in the past. The industry had to compete with the synthetic fiber industry in many aspects. One of the major drawbacks of the silk industry in Kancheepuram was the lack of support from technology. The industry was on the brink of extinction due to the obsolescence of the designs and design making procedures. This is because, design adds splendor to a saree and forms an integral part of its exquisiteness. The recent developments in the designing field show the introduction of computerized Jacquard borders in Kancheepuram silk saree. The use of new technologies has not only helped in creating new and complex designs but also reduced the time involved in the process. There has been an increase in the exports.
