I have heard rumours of people gathering spider silk and spinning it into yarn. Here's a group that produced just such a textile today. Wow! The golden colour is the natural colour of the silk. The brocade weaving is 11 feet long by 4 feet wide and is made from the silk of 1 million spiders.
These spiders bite. And they are huge! Each spider donated 80 feet of silk to the textile, which is on display at the Museum of Natural History in NYC.
