My mum's next door neighbour recently bought two balls of the popular frilly ribbon in the hope of teaching her granddaughter to knit but once she looked at the yarn, she realised it would be way too fiddly and she kindly passed them on to me.
Once I'd had a look at a YouTube video (you can find instructions for anything there!), two evenings later I had two pretty frilly scarves. Anyone who's knitted with these will know that the yarn comes as a flat ribbon and you have to spread it apart as you go in order to knit it up. It looks a bit like fishing net.
