Back in 2015, when I was a new spinner, I tackled some beautiful silk hankies. They are nothing like “regular” fiber.
The basic technique is to peel off one (very) thin hanky, poke a hole in the middle, and draft it out however much you want prior to spinning. The less you draft them ahead of time, the more you must do when actually spinning. The fibers are very long and it is a challenge to draft them at all while spinning. It actually hurts your hands because silk is a very tough fiber.
Forward to the present. I want to knit a shawl using the hanky yarn I spun way back then, BUT I also want to include some undyed hanky silk (which is pearlescent white) with the purple/gold/blue that I have from before. That means hanky spinning!
Luckily, I know more now than I did then. I very quickly realized that this is a time when I want to pre-draft the fiber out COMPLETELY before spinning. That way I have more control over the drafting process, and no damage to my hands while spinning. The spinning process in this case is actually more like plying, because I am just making sure there’s enough twist as I put it through. I’m spinning it on 12:1 and feeding about an inch with each treadle.
I’m really happy with the results.
