I'm partial to little girls because I have 3 grown girls and 2 small grandchildren who are girls. I'm equally partial to little boys because I have only one and he's 20 years old.
We have a pattern called Camaraderie / Fandango from Zanav that combines yellow, pink, and what we call a spearmint green. It's lovely and can be used with one or both of P Kaufmann's checks -- Checkmate / Sunshine (yellow and white) and Call Me / Petal (pink and white). Let us know if you need a sample of these patterns.
