It's got Link and Zelda standing together, separated by a heart container.
I'd also possibly like a Hyrulian crest at the bottom and maybe have the whole thing surrounded by a border of Triforce (Triforces? Triforci?). The middle can be blank as I'd like to come up with some sort of quote and then my friends' names and their wedding date on it. My problems that I'm running into is trying to figure out how to lay all this out into one KG-Chart file, so if anyone can help with that, that would be awesome (plus I'd love any suggestions of alternative ideas, too)!

EDITED TO ADD: Oh! A though... perhaps the border could be rupees and triforce? Or even just rupees.
