A movie marathon? The Twilight series, Lord of the Rings, Pirates of the Caribbean (my favorite :P) ? And maybe try popping popcorn on the stove the old-fashioned way and a movie trivia afterwards (maybe a prize for the winner)? You can rent all the movies (if you can get them all in time) from your library for free.

My twin sister and I are turning 17 on Friday and are gonna invite maybe 5 friends (4 girls and 1 guy) to our house. We don't really want to go out and spend money. I was thinking about us all making pizza from scratch but I have like no idea what else to do. I need more ideas and fun things to do at home..? Thanks!!
