In Mette Units 7, instructions are provided for nine models of modular origami rings, boxes, and geometric shapes. In particular, the Santiago Ball (cover model) and Santiago Flower are included. These were created at a convention in Spain. 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.
