The original Mette Units book contains instructions for fifteen models. All of the origami units are based on the Sonobe' unit, and can be used to create many different geometric shapes. All assembly instructions are in color. And, as in all her books, Mette Pederson's instructions are clear, straight forward, and easy enough for even beginners to follow. This book was previously self-published.
