I'd like to see a book that presses flowers that one collects from all over the realms. Simply pick the flower and insert between pages. After a short time one has a pressed and dried bloom of whatever species. It would be even nicer if the book could be examined to show it's contents. When turned to a given page, the flower could have detailed information on the page's blossom. Like coin collections there could be a bloom enthusiast that would buy rare dried blooms or entire collections if desired. Perhaps the distant or rare blooms could be valued accordingly.

P.S. This system could work for butterflys and beetles but those would have to be coded in. X
