Have also done a couple of can-can scarves (not as fast as you -can only do a dozen or so rows at a time, then rest) and am now doing a 'frilly' scarf -the yarn is called Frills!! I also did a bobble one -it is so soft and was easy to knit. I'd like to do another of those.
Do you do the can-can ones short, using one ball for 2 scarves, or long - one ball per scarf? I saw some short ones selling for £15 each at a local shop where I sell my cards.
