It's no surprise then, that I would gravitate toward this lovely-in-its-simplicity greeting card.
Nastasya and Zdrok operate a small paper cutting studio in Kiev, Ukraine where they make a variety of cards and art pieces by hand, both commercial and custom. Visit their Etsy shop, Mimimi Cards [edit: no longer open], to see more of their elegant designs. It hasn't been open very long at all, but is already proving to be quite popular.
