Spud and Chloë Super Soakers - Thought it must not be a free pattern after all because I could not find a download, but after clicking through a few more pages in the blog, I found it. Here it is: [http://www.spudandchloe.com/blog/wp-content/uploads/2012/01/SuperSoakers.pdf]- Brilliant shaping. Looks like a garter stitch shawl until you assemble it according to the pictures, and then voilà! Easy peasy.
