I made this scarf a while ago and found it in a case filled with projects.  I saw this and thought that there is nothing more vintage than a granny square scarf.  It was made using Patons Eco Wool Chunky. This wool is absolutely lovley to work with; untreated and I think un-dyed.  It's now discontinued, but if you can get hold of any it's lovely.  I had it left over from another scarf and hat I made but they are with the wearer.
