A brand-new origami concept: folding by numbers makes paper folding easier and more precise. And look what kids get to fold: buildings, vehicles, animals and more, to create your own play city on a fold-out play mat. The pleasure of papercraft meets the creative build-and-play fun of Lego. Three-in-One Package: 104 pages of folding paper, a 40x28 inch fold out map, and book of 160 pages of instruction. Here the origami does not exist in isolation - each model is part of the larger city. Softcover, 264 pages.
