All that glows is not silk. Bamboo Rayon is so shiny and soft that you want to roll around in it. It can be spun as is...slippery though it is. It is reputed to be antimicrobial. I don't know if that is true, but it's neat to think about. It is not strong like silk, so I would not knit socks with it. But for a drapey scarf? yummy! I like carding it in with other fibers to add luster and drape to otherwise springy fabric.
