Tiffany Theme personalization!

We are having a Tiffany Theme e-party. I am looking for things that I can personalize without just doing name and date. Why is it that it seems all you can put is a name and a date? We would like to be able to put the longitude and latitude of the beach where we got engaged on some ribbon and maybe some napkins or something else... does anyone know where I can get this done??

thanks
Cat
