Nautical Chart Invitations

I came across these invitations, from Nautical Stationary which are perfect! I thought I thought up this idea myself, but this group beat me to it. And after tons of online searching, they seem to be the ONLY invitation designer using nautical maps.

Particularly if you are sailor types.....I've been emailing with the people there, and they sent me samples, which I'd highly advise given that all the different coastal areas will look completely different once laid out on the invitation.

Let me know if you've heard of other designers that use nautical maps.

Thanks!
