Just had a look on U-tube, I am sure I have seen it on create and craft, there is a fair bit about using it on u-tube, looks interesting, I though when you mentioned it that it was something like the French knitting we did years ago, where you had a bobbin with nails round it, and you would use a nail to turn the wool over each pin to make a stitch, but it nothing like that...good luck with it though/...
