Here's what I did for my step-son's 11th birthday party this year. He got to invite all of his friends from school & church to spend the night with little business card size invitations that I printed out at home and cut out of cardstock.
I made this cake. It is real fudge icing so it's not perfectly smooth like fondant. The orbs are bamboo skewers covered with fondant. I made the white cake petit fours for those who can't eat chocolate. The disks on those are fondant as well. The 'Retro Picks' poked into some of them are toothpicks with store-bought snowball pompons glued on. (A great way to make cheap appetizer picks for any appetizer!)
