Last month for my son's third birthday we celebrated with a CARS birthday party.  The Disney movie CARS is his favorite!  I created an invitation using pictures of Lightening McQueen found in a coloring book.  On the front of the invitation I put a large picture of Lightening McQueen.  Above it were the words: Aaron is 3 years old!  And below the car it said:  Ka - chow! On the back of the invitation we put the party information with some cute phrasing: This year has zoomed by! We'd love it if you could cruise on over to help us celebrate. For location we put: Aaron Speedway I used a smaller picture of Lightening McQueen on that side and  clip art of racing flags. I made a sign out of green poster board that looked like a highway sign.  It read:  Aaron's 3rd birthday, next right  We put that out by the road.  We used racing flags and black and white balloons to decorate.(Most race flag decor was found through Oriental Trading Co.) The cake was a race track made with two round cakes put together and decorated to look like a figure 8 track. (Idea found through Family Fun)  The candles were two cars, a trophy and race flags.(candles were a set from PartyLand) We also had cupcakes with mini Lightening McQueen and Mater cupcake toppers on them. (found at Party City)  This was an outdoor summer party, and it was a very hot day so we had a water slide in our yard. The slide had two lanes, and it had racing flags on it. I found little oil can squirters in the CARS party section. We put a bunch of them in the baby pool.  We cleared out our fenced in garden area and turned it into a race track.  The kids raced R/C vehicles there.  We had a large blow up Lightening McQueen for the kids to climb in.  I made a Piston Cup trophy out of poster board.  I had each child climb in the car and hold the trophy for a picture. One of the party favors they went home with was a racing photo frame kit (OTC)  When I send their thank you notes I'll enclose the photo so they can put it in their frame.  We had a table set up with little wooden race cars and wood markers (OTC) for each child to make.  We had racing tatoos for everyone.  We decorated the back of our house with a scene setter purchased at Party City.  It looked just like Radiator Springs! I found cheap styrofoam coolers at Walmart.  I painted them by driving one of my son's toy trucks through black paint then driving it all over the cooler. It was cute - the cooler had tire tracks all over it.  I did the same with black fabric paint on a t-shirt for my son to wear at the party. He loved it. We had some old tires out back.  We stacked them then put a trash can in the center for trash. We played the CARS movie in the house for anyone who wanted to escape the heat, and on the walls we taped large poster pictures of the CARS cars to be colored in.  I saved cardboard cars the kids got from a restaurant and we used them to hold the crayons near each poster. We had the CARS playrug and some of the CARS cars set up inside too.  We used orange cones to decorate on the driveway where we set up the toy garage and matchbox cars.  We played the soundtrack to the movie outside as we videotaped all the kids enjoying the activities. The other party favors were balloon race cars and little racing flags, tatoos and the frame mentioned above. All were purchased through Oriental Trading. It was a great party! Everyone had a wonderful time. My son is still talking about it!!!
