Color 1 is for the hat, diaper cover, booties, and the turtle shell. Color 2 is the trim on the hat, bootie, diaper cover, turtle shell outline and the flower if you yould like a bow instead then just answer the question to the side.
 
PLEASE NOTE:the sizes goes by what the child wear not by age since this is crochet clothing. For example the baby is 6 months but wears 0-3 in clothing then you will need to get the size 0-3.
