Moleskine, that beloved notebook of so many so far and wide, has just relaunched their website with a new "MSK" format that lets you print your own pages (including a wizard that helps you along--why do things always need a "wizard"?!) It also boasts a gallery of special projects, user-created artwork, and a line-up of special editions. Things are just getting populated, but let us know in the comments how you like the printable pages and links to your favorite (or your own!) artwork.
Too rich for your blood? There's always this old standby.
