You can navigate to /private/var/mobile/Library/Notes. The notes.sqlite is the conglomeration of all notes that you have. If you change the extension to .html from .sqlite, you can view it on a browser, but that's it. You can't specifically choose which note that you want because they're all saved into the single notes.sqlite, and you the recipient can't open it on their device unless they want to overlay their current notes.sqlite even though you're opening a cached notes.sqlite
