At last I have a finished project, started and finished after my hand surgery.
I bought two balls of Jaeger silk, in a light turquoise, on e-bay, largely on the strngth of seeing Wendy knit a top in the same yarn. It's quite a heavy yarn without much lustre, but the thought that it was 11.50 per ball originally does create a sense of luxury.
I've knitted a scarf in travelling vine pattern and,although it is heavy for a summer scarf, the colour is light and summery. More than that, of course, is the relief of being able to knit at all.
