Back in my college days, I fancied myself an amateur bookbinder. I took letterpress classes, bookbinding classes, and calligraphy. I scoured the web for decorative paper suppliers, and amassed quite a collection of hand-printed styles.

The web developer in me is still a bit sad, though, because decorative paper is an area where you are still better off looking in a real, physical store for the best stuff. This is changing, albeit slowly, as more and more small businesses make the jump into electronic commerce. But there's still going to be a bit of a wait.

For the time being, a few sites have started to spring up:

Dick Blick (http://www.dickblick.com/categories/decorativepapers/)
Dick Blick, as always, is a good place to go for basics. It also can be a nice place to start researching different kinds of papers and what their general prices are.

Kate's Paperie (http://www.katespaperie.com/paperwall.html)
Kate's Paperie is a paper-lovers mecca. I spent a summer in New York as an intern, and I literally went to this store once a week. They have books, papers, pens, stationery, notecards - you name it. Their online store is somewhat primitive, but you can find a decent selection.
