My oldest's 3rd birthday party was dinosaur themed. Here is what I did to make it pinteresting.
We had lots of toy dinosaurs at the house. So I took a clorox wipes and wiped them down to clean them off since I was putting them near food.
I took some plain green cards folded them in half and put some foam dinosaur stickers on them. I gave the food some dinosaur themed names.
-Veggie Tray was an Herbivore Buffet
-Pistachio Nuts were Dinosaur eggs
-Salad with pomegranates was Herbivore Delight.
All in all it wasn't time intensive and it was really easy to put together. It was a creative way to set up the table with out spending hours making decorations or place cards.
