Once I got back into the rhythm of knitting this scarf, it was pretty fun. I held the 2 yarns in separate hands. While it's not necessary to do this, it was easier to shuttle them back and forth without getting them tangled and stuck to each other this way, especially given the nature of Kidsilk Haze.
I'm enjoying the finished scarf! Details are on Ravelry.
There's an idea that's been bubbling around in my head for a different scarf design ever since I took Lucy Neatby's double knitting class at Madrona 2 years ago, but I haven't worked on it at all. Since I have plenty of KSH left over, I might swatch something. We'll see.
