Ziggy is being done on 4.5mm needles, named 'Purple Heart' all the way from Books, Yarn & More in Montana, USA. They do awesome needles, take a look! I got the yarn from Joyce Cook at WonderWool Wales 2009 (unfortunately I don't have a link), the yarn is hand dyed. It is DK although the pattern states Worsted weight, I may have to jiggle things, I shall have to see when I get closer to the end!!
