Quilling, creating note cards, etching and more. I did a little digging and found this page, linked below. Of all the ones I saw, this one seemed to have tons of amazing examples and the history of paper arts. Kind of a one stop shop to get an eye on some examples to help your question get more results! http://www.webdesignerdepot.com/2009/05/100-extraordinary-examples-of-paper-art/
PS...I have seen people create miniatures out of paper. Check youtube and search paper miniatures and you will see a bunch of cool things!
