A simple but effective way of keeping my little girl warm - I made it with 4 balls of 8PLY pure wool (machine washable of course, nothing else can ever live in toddler-land) and crochet hook size 4, and an easy peasy chevron pattern. It had to twirl - obviously - the signture of a good skirt. It will need elastic around the middle as the wool stretches very quickly. Happy days!
