Place Cards: A really easy idea for a place card (or food label) is to "doodle" on a piece of cardstock paper and attach crayons to it.

Centerpiece: A few months ago I created some centerpiece ideas that I shared here. I took this basic idea and Elmo-ized it.

Plates: I recently created some Halloween-themed plates. Again, using this same idea, I made Elmo and Dorothy (his favorite pet) plates...

Placemats: Have you ever noticed the adorable pictures that hang on the wall in the Elmo's World episodes? A really easy idea for placemats is to draw those pictures using crayons on a piece of cardstock and laminate them.

Food: I thought it would be fun to create Elmo using food. Here's the result...

The items needed for this vegetable tray are:
Head = Grape Tomatoes
Nose = Mini Carrots
Mouth = Black Olives
Eyes = Ranch Dressing
This same look can be achieved using a fruit tray. Here's how:
Head = Strawberries
Nose = Mandarin Oranges
Mouth = Black Grapes
Eyes = Banana Slices
Hope these ideas are helpful if you're planning an Elmo-themed event!
