When asked by his parents what he wanted to be when he grew up, five-year-old Eric Gjerde replied, "a paperologist." Throughout his childhood and adolescence he enjoyed paper crafts and origami. After preparing for a technology career, Eric kept looking for an artistic outlet to balance his creative side with his professional life. He returned to his childhood love of paper and discovered a deeper appreciation for the beauty of origami by exploring and researching new areas of folding--including the geometric art of origami tessellations. He currently balances dual careers as a technology professional and as an artist in Minneapolis.

... It is surprising and challenging to see which variety of ornaments can be generated this way out of one single sheet of paper. The procedures are explained step by step and allow to reproduce these interesting planar ornaments. ... The surprising and wonderful results are worth the effort. I really enjoyed this exercise ... [the book] can be recommended to whoever is interested in the field of planar ornaments and its connection to origami.

In this gorgeous book, Eric Gjerde has presented clear, easy-to-follow instructions that introduce the reader to the incredible beauty and diversity of origami tessellations.

Here [Gjerde] demonstrates 25 of his favorite designs that use tessellations, geometric patterns that can repeat forever, to make paper surfaces of intricate pleats and folds. For most learners, he says, there is a moment of epiphany after which it all makes sense and they can never go back. Beginning and experienced origamists are welcome.

If Eric Gjerde's new book Origami Tessellations: Awe-Inspiring Geometric Designs needed an alternative title, it might be: Origami: It's not just for kids any more! Of course origami has never been just for kids, but this book should convince you that you can create some great art using origami techniques. . . . The projects are graded as beginner, intermediate and advanced, but 'beginner' should be interpreted as someone who has previous experience with origami or a strong interest in learning about it, because even the simplest projects include a lot of steps and demand precise folding. But for someone who enjoys doing origami and wants to try some complex projects, the directions are very clear and the photographs of the finished work should serve as an inspiration.
