This is a awsome idea and it works great. what i did for my 14th birthday party was a homade theater. i invited about 100 frieands and we all gathered in my back yard. The yard was clean cut of course! We set up a sheet and a projector screen, and big speakers on the back wall of my house and set up a projector we watched movies on a big screen (the sheet on my house)we sat on the floor on huge beanbags and chairs. towards the back of the yard we hade a rental popcorn machine on a table with sodas in a ice chest next to itof course you can have hot dogs, nachos, pickles and stuff like that, all the theater food. the way we got in the party was across a velvet rope wich we bought. it is very fun if you get scary movies to watch in the darkness of the night. goodie bags were popcorn boxes filled with candy and goodies like that. the invintations looke like admitt one tickets and the cake was a monie theater screen with the credits containing my name. it turned out to be a huge success. we ever had colorfull lights everywhere so when it got dark we could lighten up the place in a fun way!
