Race Car Party Theme: This is a great party theme for all those little NASCAR celebrities. This action packed adventure ride is sure to thrill boys in the age group of 6 to 10 years. For the party invitations you can use cutouts of cars or have graphics of race cars on the invitation. You can also choose invitations with graphics from the Disney movie Cars. The decorations should include black and white color theme and a host of checkered flags. For the party favors stock up the goodie bags with small toy cars, sunglasses, plastic keys and car stickers. Elaborate party favors allow you to get hold of the pit crew outfits with colored T-shirts and baseball caps which have car logos.
