When you are having a themed event, it is important to have a party "logo" to establish your theme on the various party elements. This logo can appear on the main party signage, as well as favors, invitations, place cards, etc. Here is an example of a logo I created for a candy-themed Bat Mitzvah! I did two different color schemes on this one, to see which coordinated with the theme colors the best... A detail like this can really "brand" your event!
