I just started working on this dress. I am using 3 balls of Bernat Organic Cotton in Prairie Rose and US3 needles. I'm going to follow the pattern as directed in Zoe Mellor's book Nursery Knits. I just can't find the other type of yarn. Catherine is 8 months old and the pattern gives me a 9-12 months dress. I'll take pictures as I go. It is too cute to pass up.
