Later that year Bolt Threads also unveiled its first collaboration with designer Stella McCartney, a dress made with Microsilk fabric, unveiled at the New York Museum of Modern Art’s exhibition titled, “Is Fashion Modern?” and last summer the collaborative partnership produced its second prototype, a biodegradable tennis dress, created with a Microsilk and cellulose blend.
These prototypes have proven the possible commercial functionality of spider silk, but for now it remains significantly more expensive than its traditional silk counterpart. “Now we need to scale it,” says Widmaier, “we need to make it cheaper better, faster stronger… but it can work.”
While there might still be a wait before Microsilk hits the fashion mainstream, the company has another biomaterial invention up its sleeve. It’s one that Bolt is already producing in massive quantities and could well turn the leather industry on its head. It’s called Mylo, and it’s made from mushrooms.
