I recently did one for my niece. She's a little older (9). I did pinwheels/solids. The pinwheels 'flowing' kind of like a kite tail throughout the top. Used colors in her room as DB and DSIL said it was staying those colors for a LONG time. Used flannel on the back only. FWIW I would highly recommend Moda Marbles flannel. It's beautiful! I'm not really fond of their cotton marbles but the flannel was delicious. And definitely prewash as others suggested.
