If you like the invitation...do you want some fun favors to match?
You may already have favors and not need anything, but if you do want some...here are a few fun suggestions for movie parties. First, go check at Target in the dollar isle and see if they have the red and white popcorn holders. They often have them available and they are only $1.00 each and super cute. Then you can either use them to hold favors or you can buy one super size popcorn tub at the movies and use them so that each child has their own popcorn...then they can take them home as well. You will have to take a large purse to get them into the theater. I have also seen them at some of the dollar stores.
Another cute favor is individual microwave popcorn bags with a "party" wrapper around it...similar to candy bar wrappers. Or a red and white popcorn pouch (I have one in my 4shared file in the candy wrapper" file then "miscellaneouse wrapper" file with blank boxes on it for personalization. You will need to print a front and back to the pouch. Use the tabs and double sided tape to contect the sides and bottoms together. Then the individual packet of popcorn slides inside the top.) If you were willing to hand deliver the invites...this would also be cute to give with the popcorn and "ticket" tucked inside.
You could do baggy toppers and fill the bags with fun "movie" style candy to pass out during the movie when the kids get restless, or even buy the boxes of candy at
Walmart for $1.00 and make a wrapper for them.
Finally, you could do the ever popular candy bar wrapper. I have a movie candy bar wrapper in my 4shared file (which matches the microwave candy pouch that I mentioned earlier) I or if you wanted...I could make a toy story wrapper.
To save a little money as food is way overpriced at the theaters...take an extra large purse with juice boxes for drinks for the party. Or take cups in your purse and buy a couple of super sized drinks (with the extra large popcorn

) and pour them into the individual cups to pass out. If you decide to go this route...find cups with lids as drinks always seem to get spilled at the movies.
Just some fun ideas if you needed them.
