So for DD's 1st birthday we want to make it a superhero theme (encouraging people to wear their fave comic shirt, etc.). It will be during lunchtime and sandwiches (aka "hero"s) will be served.

Should I write something on the invitation about a light lunch (so that people dont assume to be stuffed!)?? I was looking for wording that would go with the superhero theme, but i cant find anything.

anyone creative that can help?
