Absolutely. You can mix and match all the books together. Obviously some fit thematically and aesthetically better in appearance but they are made to be integrated.
You are not supposed to rip the pages out. You are to put the minis on the book that is opened to the desired theme. Want a different theme open to a different page. Mat size options range from 1’x1’ to 2’x2’ (24”x24”) The company offers other size mat options
