Yes, doing it on circular needles... 90cm long.
Thanks for all of your tips... I liked my swatch done on the size 15's. I'm still perfecting my tension so it seems to be a bit looser, but not too loose. I found that the size 17's would be too loose - to the point where fingers and toes will poke through (The blanket is for my boyfriend and this would really annoy him :P )
