Jenni,
You wanted ideas about a girls Christmas party...any specifics in mind? What are the ages of the girls to be involved? What kind of stuff are they "in to"? What kind of money did you want to put into it? Would you want to use recycled crafts or craft kits? If you can give me more details about what you are looking into doing, I'm sure I can come up with some suggestions (since I have twin girls).
