This book was created with beginners or people that have conditions where coloring in small spaces is difficult. The lines are thicker then a normal adult coloring book and designs are less detailed. Its a great book to just relax to and de-stress. If you would like this book in spiral bound format with thicker pages please purchase it here: http: //www.amazon.com/handmade/Handmade-Crafts-and-Supplies Please note that I only send spiral bound books to the US at this time.
