Finito! Here's the Prism Shawl I made with Noro Silk Garden Sock. It only took one skein of each colour, so two balls, and knitted up fairly quickly, considering it's a sock yarn. I'm not sure, but I think the off-white colourway (269) is discontinued, so if you want to make this it's a good idea to pick up a skein before they all disappear. I think we have 4 or 5 left at the store.
My only caveat about the pattern is that what they call a 'M1' increase is actually a backwards loop cast on. They give you a link in the pattern, I advise following it to confirm the technique.
