These five pictures illustrate some creative ways to bind a multiple use book for a hardback case. On the left side of one picture, there’s a cavity which a book is inserted into. One picture shows the white book being slipped into a pocket on the right hand panel of the large cover. One picture shows the elastic size closure. This particular project for us requires a number of operations, die-cutting, case making, gluing pockets, riveting the elastic black closure, perfect binding. In total, nine operations. So, if you need something that is this complex for a hardback case, we can probably help.
