Unspun silk is super fluffy! I was surprised. The other night I took my mawata / silk hankies and started playing around.
BMFA Mawata, colorway Aurora Borealis
I peeled off a layer, stretched it out until the center became so thin it turned into a big ring of fiber, then broke the ring and yanked on it until it evened out thickness-wise.
I then took my newly-formed cotton candy fluff and cast on for some mittens.
You can see that I haven't quite got the even thickness thing down yet. The stitches to the left are kind of sport-weight sized and the stitches in the middle are worsted/aran weight sized. No matter since I'm frogging this anyway. I suffered through several rows before I realized that the reason every stitch was being a pain in the butt to knit was probably because I was using bamboo needles to which the unspun silk clung too tightly. I'm waiting on some new metal needles to arrive before I continue with my fluffy mitten adventures. I'm excited, how about you?
