This is 262 yds of cotton yarn, spun with roving made from recycled blue jeans (plied with my usual commercial cotton strand). I don't know where I got the roving (sliver is the really nicely prepped stuff, this was regular roving- carded and aligned but not combed or smooth), and I have no idea what I paid for it, but I do remember that it was made entirely from shredded blue jeans. The roving still had tiny bits of darker blue threads in it (and here and there, a red thread). It spun up okay, though the yarn has its thick and thin places (well, all of my cotton yarns have thick and thin spots, but this one has more of them... mostly thick).
Last night, I spun up all of the denim roving that I had, and while I'm not looking to buy more (the Moratorium extends to spinning fiber too, as well it should), I did want to post some links to the recycled roving in case any of you want to give it a try.
Guess what? I couldn't find it anywhere. Not on eBay. Not on etsy. Not via Google or Yahoo. I barely found a mention of this stuff, much less any for sale, or any info on how it was made, or how to spin it. It's a Mystery Fiber, I guess. And evidently, I got the very last of it, purchased on a whim, and forgotten for years.
