I threw my son a Mario Kart Wii Birthday Party. And as usually with the themes my kids pick, there weren't many options at our local stores. So, I made almost everything for the party myself. Click on the links below to find out how you can make them too:

I also bought Mario Kart Wii Wall Stickers, since I didn't have time to make them myself. =) We had a great time and best of all, my son was over the moon!
