Finally a fiber I can Identify!  While looking for some magnets for a project of my mother’s I found some old silk ‘hankies’ I had purchased to spin.  It was a blast spinning these yellow/gold ones into threads and after they have rested I look forward to plying them.  Yes, I’m still working with Toilet paper roll centers. they work really well!  Okay, so I don’t have a Lazy Kate either, I managed to ply a 2 ply yarn without it, so I hope this goes well!
