I was given some lovely silver grey, soft fiber. Wish I knew what it was but I don't. I went to some fellow fiber fanatics - they all say think it is synthetic. I'm not a huge fan of synthetic but this is great stuff. I spun it thin and plied it with black tencel. Wow! I love it. It wound up being around 420 yds. I think it wants to be a lovely lacy openwork scarf. Will let ya know when I start - meanwhile I have other stuff to work on - like some purple and white to spin, some BFL/Cheviot to drum card, and several projects that need some finishing...- Too much to do too little time!!!!
