For DD's 10th birthday this year, we are throwing her a big birthday bash at our house and using mostly things that we already have at home. Invitations: paper invitations made on the computer. Decorations: mostly balloons and streamers on the backyard fence and throughout the house. Food: we are doing a buffet...grilled hamburgers and hotdogs with burger fixings (cheese, lettuce, tomatoes, pickles, condiments), individual bags of various chips, cheeseballs, a fruit plate, and individual boxed drinks. Around the house, we are placing bowls of fruit snacks and pixy stix.  We are having both outdoor and indoor activities. Outdoor activities: rented bounce house with slide, trampoline we already have, moon shoes, pogo sticks, hula hoops, and skee ball. Indoor activities: lots of wii games that we already have (such as DDR, guitar hero, rockband, high school musical, wii sports, outdoor challenge), ping pong and air hockey tournaments, video miniature golf (its the type that you plug into the tv and use a putter), and we set up a karaoke room. Later in the evening, we are rounding up all the girls for two craft projects: fluffy flip flops and charm bracelets, which will be the primary party favors. Instead of a cake, we are baking cupcakes and doing a cupcake bar. We will have various flavored cupcakes set up on a long table in tiers alongside bowls of strawberry, vanilla, and chocolate frosting, sprinkles, crushed oreos, gummi bears, gummi worms, candy corn, chocolate chips, and m&ms. The girls will get to vote on who came up with the top 3 cupcakes and those girls will win a prize.  Then we will have a dance party in our media room.  We removed all the furniture, retracted the screen, and put up hanging decorations from the ceiling and scene setters on the walls. I made a playlist of my daughter's favorite dance songs and will plug her ipod with the playlist into the media room surround sound system and voila -- 2 hours of dance music.  We bought a mini strobe light to add some effect and also bought several glow in the dark bracelets for each girl to wear while dancing. We also shredded brightly colored paper and filled paper bags and ballons for the girls to pop. After the dance party, we are lowering the big screen and the girls will watch Sleepover, the movie, snack on individual bags of popcorn, movie candy and drinks, and give each other manicures.  They then can watch other movies or play more games or dance until they fall asleep. There will also be late night ice cream sundaes. There is a roll of paper on one of the walls for the girls to write birthday messages for my daughter. In the morning, we are making them belgian waffles with orange juice or milk. Then they will be picked up and its time to clean up!
