The staple is super-short and a bit challenging, but it's spinnable as-is. I've been using it to add sari-silk stripes in core-spun yarn, though I also tried spinning a thin single approximately dk weight, and that was really interesting too. Of course, the BEST use for this gorgeousness is carding. Add a sprinkle here or there sandwiched between two layers of fine wool for a confetti-batt, or feed directly onto the drum and "paint" the sari silk wherever you'd like it. I also finally ordered lovely sari silk threads, which my Louet Classic accepts hungrily without damaged teeth.
I've been adding globs and tangles of this beautiful mess into my ArtBatts and am now tempted to spin a chunky black alpaca yarn with giant globs of rainbow sari-silk and silver angelina sparkle. Or maybe a white sparkle-batt with giant chunks of random colors.. I just want to spin this madness, but I've got a pile-up of rainbowish bagged fiber to card, and three seasons of Downton Abbey in my queue. I can't lose, it's going to be a great night in the studio after the littles are tucked in!
