The Pocket Paper Engineer, Volume Two, covers four important glued pop-up structures: platforms, props, spirals and straddles. These forms are used in many of the fabulous pop-up books on the market today. As in Volume 1, projects can be detached from the workbook for construction, then stored in pocket pages within the book. Ten projects are included, along with lots of lively illustrations and design tips. This is a workbook for adults and children alike who want to hone their paper engineering skills. 6 x 9.5 inches, 68 pages, wire-O bound in a hard cover.
