I have never done this in my life. I can knit (the very basics!) and my nana used to do some amazing crochet pieces from really intricate little mats and cloths to big colourful chunky blankets - which is what I'd love to make - a poorly blanket for my children! Where do I start? I bought a 4mm hook and some yarn today to have a play but would be greatful if anyone could recommed any good sites or books to help me.
