Christmas slumber party ideas?

Hi, I'm 15 and me and my sister always have this annual Christmas "party" with my friends. They just come over and we watch Christmas movies and bake cookies and stuff like that. I was wondering if anyone had any other ideas for stuff we could do? We have board games and stuff like that but maybe something a little more fun. We are doing a gift exchange since I get my friends Christmas presents and we just like to give them to each other all at the same time. We dont have snow yet so please dont suggest a snowball fight or sledding or something even though that would be really fun :) There will be 5 girls total including my sister and myself. Any answer is appreciated :)))
