FiftyThree, the company behind the hugely successful Paper app for iPad, has partnered with posh notepad firm Moleskine to offer hardbacked editions full of your favourite digital art.

Book is a collaborative scheme whereby you can have a 15-page foldout book of your Paper journals. It costs $40 a pop, but feature colour-matched printing on sustainable matte paper. You can also choose between a custom or traditional Moleskine hardbacked cover.

The foldout pages ape the 4:3 size of each of your Paper creations. They also represent the first time that Moleskine has created a journal in this form, a brand new format just for this project.
