A rare textile made from the golden (colored) silk of more than 1 million wild spiders is the only fabric at this size made from natural spider silk which is extremely difficult to harness at mass amounts. It took 70 workers 4 years to make this fabric in collaboration with the spiders. The silk is stronger than steel or kevlar and researchers have not yet been able to imitate the tensile properties of spider silk which can stretch up to 40% of its original length and not break. via Wired
