Know-How Exchange : Other

Can anybody give me some ideas for "out-of-box" creative wedding invitations? For example, my friend used to have invitations in a form of the pack of two toothbrushes with the printed names on them with the message "Join us in the celebration of the beginning of living together".

So, I want as well to make this type of invitation (but not toothbrushes), but currently have no idea. Maybe somebody has... If so, please share and help me in organizing my wedding :-)...

Thanks
