I am making these afghan squares so that I can put a new baby blanket together. I am making them with a round centre and then I might make some others . I want the blanket to be able to fit a bassinet or a pram. It's a good way for me to use up the odd balls of baby wool I have. I really like the softness of the colours and then how quickly they come together. Granny squares are a good take anywhere project. They fit easily into a small bag and don't weigh much.
