Dozens of Saudi craftsmen, mostly in their 40s and 50s, are hard at work in a factory in Makkah preparing an embroidered black and gold cloth to cover the Kaaba, the holiest site in Islam.

Known as the kiswa, the cloth is woven from silk and cotton and adorned with verses from the Qur’an. A new one is made each year to be placed on the Kaaba in Makkah's Grand Mosque during the annual Muslim Haj pilgrimage, which begins on Wednesday.

Many of the craftsmen have worked in the factory in the Oum Al-Jood district of Makkah all their lives but they will retire soon, so a new generation is being trained to carry on the trade.

General Manager Mohammed Bin Abdullah Bajuda said Custodian of the Two Holy Mosques King Salman had ordered all the machines, which were introduced some 30 years ago to help automate the process, to be replaced with newer ones by next year.

"He also called for a new cadre of manufacturers to take the place of the current one," Bajuda said during a visit to the factory on Saturday.

The kiswa was manufactured in Egypt until 1962. There have been red, green or white coverings in centuries past, but now it is always black with embroidered gold calligraphy.

Nearly 670 kg (1,477 pounds) of silk, enough to cover a structure estimated to measure about 50 feet (15 meters) high and 35 to 40 feet long, is imported from Italy. Silver and gold-plated thread comes from Germany.

But the kiswa is embroidered and stitched together in Saudi Arabia and paid for by the Kingdom each year at a cost of $6 million.

Waleed Al-Juhani has worked at the factory, which opened in 1977, for 17 years. "Thanks to God we are working to serve the holy Kaaba. This is a great blessing," he said, while embroidering a Qur’anic verse that takes 60 days to complete.

"When we succeed in our work, we are glad that Muslims will celebrate a new cover for the Kaaba. This is the best feeling."

At the end of Haj, the used cloth will be cut into pieces to be distributed among dignitaries and religious organizations. Recipients regard the fragments as heirlooms.

This year's kiswa is complete, but the workers have already started on the next one.
