In Mette Units 3, instructions are provided for nine origami models. Similar to her previous books Mette Units and More Mette Units, there are a few origami units based on the Sonobe' unit, which can create many different geometric shapes. There are also three quilt units, a ring with variations and a star. 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.
