Tuck away your coins and small mementos for safekeeping in this nested storage book. Comprised of 31 compartments, the design features layers of folds, meaning that the 16 flowers on top and the pockets supporting them open up to reveal small compartments that vary in size. Originally, the paper books, which are called zhen xian bao, were used to hold thread and other embroidery materials—this article dives into the history behind the traditional Chinese practice—and would unroll in multiples from a single binding. Watch the tutorial above for folding basics, and check out the written companion for instructions on scaling up the design to 127 pockets.
