Smitten (colour: soft slate) left over after determining the ball-band gauge, and I've been admiring the Yarn Harlot's Pretty Thing pattern for a while, (Ravelry link here), and, well. Just well. I knit on this just about every chance I got for three days, and I love the result!
Most significantly, a drapey lace fabric is never going to stand under the chin like the original cashmere blend does. This is more of a collar than a cowl, and I'm wearing it folded over as a result. If I were to do this again, I might take note of where the fold falls, and swap the right and wrong sides in that general region - just so that the right side of both sets of scallops shows, when worn.
A note on blocking: Wet-blocking silk is an interesting exercise. Silk tends to get 'crispy' as it dries, and you need to beat it up a bit to get the blocked object to soften. I find it fascinating that the softening doesn't undo all the careful blocking, but honest! It doesn't!
