Get fingerprint stickers and stick them on cups, tables cloths, and any surface you can find that makes them easily removable. Get posters of famous spy movies like James Bond, Spy Kids, Mission Impossible and Casino Royale, etc. I designed the inviations using stencil font of the title, added a few must-be-decipered items, and placed the inviations, along with a business card sized code breaker into a manilla envelope with "confidential" stamped on it. Some examples of encryption would be to use the ancient Egyptian hyroglyphics, write the party details in mirror image, use Morse code or make up your own.

This way kids can get excited about attending the party before hand and will be ready for bigger challenges on the day of the party. Another option is to leave the location of the party in a secret code and for those who are able to attend the party, mail out a separate code sheet one week before the party and let the kids decipher the party address or location. Put the invitation in folders or manila envelopes that has been stamped with large red letters “Confidential”, “Top Secret”, or “Mission Impossible”, etc. Tell them to make sure they are not followed by enemy spies and to remember the secret password so they can enter the private party scene. Include inexpensive dark sunglasses in the package and tell potential secret agents to come incognito to the party.


Add embellishments and stickers from scrapbook stores like small magnifying glasses, finger prints, fedora hat, etc.

Use a simple looking blank card or make an elaborate card out of card stock. Make your own super secret invitations to send out to your special guests with special instructions about the undisclosed mission location, party times and the secret password to use to enter the secured party location.
