Abstract
A concertina-bound foam-based book is presented, comprising a plurality of foam pages, each having a first edge and a second edge. The first edge is opposite the second edge on each page, and the pages are bound along their first edges and second edges in a concertina fashion with a water-resistant binding means. When fully opened, the concertina-bound foam-based book opens as a string of pages and such that when closed, the pages of the concertina-bound foam-based book form a stack of pages. A variety of specific binding means and binding materials may be used in conjunction with the present invention. A method for making the concertina-bound foam-based book of the present invention is also provided.
