For my son, Joren's, 9th birthday, he wanted a "late night" video game party... meaning a bunch of little boys come over and eat and play video games all night. Sounded good to me... cheap and easy.
I created the invitation in photoshop elements. I found a blank iPad template. I had him text me a fake conversation... I took a screen shot of it and put that on the invitation. Then I put his 4 favorite games at the bottom of the screen.
Whenever I have a party, I like to decorate the dresser I have in my kitchen. Because it was a hodge podge of iPad games as well as playstation games, I decorated with all things gaming. I had a banner left over from Brenner's Minecraft party as well as the Steve head.
I also put out remote controls on the tables, Skylanders, stacks of games, etc. Joren had bought a football gum dispenser that he just had to decorate with... it worked out great because Madden was one of his favorite iPad games as well.
Brenner made this "Eye of Cthulhu" giant cake ball... that's something from Terraria.
Aside from the fact that having a bunch of boys at my house late at night when I'm tired, it ended up being a fun party!!!
