Dinosaur Party Theme: This is my "dinoholic" nephew's favorite party theme. He somehow loved the big bad T-Rex with that hearty roar and the teeth clashing chomp. The birthday party invites can be shaped as a dinosaur head with the sharp teeth as the invite or just roll up a piece of paper and place it inside the huge "dino" plastic eggs. Decorate your room for the party in shades of brown and green to bring out the jungle effect. The party supplies have colorful graphic dinosaurs on the tablecloth, napkins, plates and the glasses. Dinosaur party stickers, notepads, pencils, figurines and dinosaur tattoo books are all great ideas for party favors.
