everyone, finally in one place

A book you make together.

Everyone in the group pastes their own photos onto the same pages. Here it is, from the shelf to Memory Lane.

  1. 01

    Your books, on a shelf.

    Each group gets its own book: the trip, the birthday, the family. They sit together on a wooden shelf and open when you tap one.

    Open it to the pages.

    Flip through what everyone has added so far. Every page is a collage, put together by hand.
