I am making a shawl from Kristin Omdahl's Wrapped in Crochet for my sister in law.
I am making this using Sublime Tussah silk yarn in Mulberry - I have no idea why it is called mulberry, its not purple at all, at a push it has a slightly blueish tint.
The yarn is a 50% Tussah silk/50% viscose blend. I hope you can see from this photograph how wonderfully shiny the tussah is.
I'm not that far through making it, I've got the medallion band at the bottom done so far.
Its difficult to see the effect of the yarn in the wider shot, so I took a close-up as well. I think it was a good yarn choice.
