How can I have the best sleepover?

K. so im having 2 of my closest friends over, and i need a few ideas on how to have the most fun. Since I usually go over to my friends house and end up being bored to death. I've already thought of giving eachother makeovers and doing eachtohers hair and having a fashion show. take pictures and stuff. if you have any ideas, make sure that their cheap, cause moneys a little tight for me. I thought of buying bags of balloons and glowsticks from the dollarstore and attempt to fill my basement with baloons. thats all i got so far. plz help. thx!
