More and more artists are seeking clever ways to make their albums and paper projects more interesting and three-dimensional. One of the most exciting ways of accomplishing this is by adding interactive elements, such as doors that open and reveal hidden layers, envelopes and pockets that hold secret text, personal letters or special photos. Pockets, Pull-outs and Hiding Places teaches the paper engineering techniques for making three dimensional and interactive 'paper tools' such as vellum pockets or hinged doors that reveal mini booklets underneath. Artists with any level of experience can use these tools for altering books, memory art and collage. The tools are also adjustable enough to be used in any style of work.
