12 Year Old Girl Sleepover

I am 12 and i want to have a sleepover. I need some ideas that will make the party really fun and exciting. I am hoping to do something possibly crafty and artsy. I will just go with the flow though. I am going to have 3 people plus me so something with that would be great. I love to cook and want recipes and links to sites that can help me with ideas for this party. Thank you all for your advice.
