Users of the free Paper sketchbook app can order custom-designed Moleskin notebooks featuring their work for £25.

Book is a new printing service from Paper app developer FiftyThree that lets you take sketches you've created in the free iPad app and order a Moleskine notebook with them within. The end result is a creative 'journal' that can be used to show the progress of a project to clients (or prospective clients), or sold as an artbook in its own right. Or, for yourself as a future reference.

To create a custom Moleskine, you select 15 spreads in the Paper app and upload to FiftyThree. You then choose colour and artwork options for the cover and spine (or just go for classic black). Finally you pay US$40 (£25) per book and they'll start shipping in early November, says the company. The books destined for us in the UK are made in the UK, and it's all printed on sustainable matte paper that's the same 4:3 shape as the iPad.

Paper is free, but has very limited tools (just a few basic drawing functions really). In-app purchases give you access to near-essential features such as sketching, outlining, colour, text and a colour mixer.

Book is almost the opposite of Moleskine's previous hookup with digital note-taking app-and-service Evernote (which I personally have come to use daily). That collaboration saw the creation of a paper Evernote notebook that's not as ridiculous as it sounds, as it was designed to be quickly captured into the app/service using your phone's camera (using a dotted grid to ensure it comes in correctly).
