While creating this book, my intent was to reach beyond current origami enthusiasts to a wider range of readers. I paid more attention to the things that more experienced modular folders may gloss over, in order to bring clarity to the process for beginners. My hope is that it will become a door to modular origami for those who have not yet tried it and introduce the art of making kusudamas as a wonderful new hobby to many readers. If you ever liked construction sets, conundrums, puzzles, paper modeling or any other challenges of the mind – you should give this book a try.
