For my 13th b-day party I had a sleepover I bought everyone a white-T.We had Fabric pant and markers.We each decorated a shirt then left them out to dry.Them as we wanted for them to dry we made a slam book.What you do is Take a notebook decorate the cover.Then on the first page each person chooses a symbol that repersent them.then on each page have a questionat the top of each page.then each person draws there sign and anwer the qustion.Then afer everone answered all the questions go over them aloud.Then by that game is over it should be time to eat.then watch a bunch of movies and stay up all night.then in the morning have a ton of doughnuts then had out goodie bags with t-shirts.Hope i helped
