This book contains 100 simple geometric patterns and 1 drawing per sheet, so you are sure to be able to color with confidence without color bleeding on the next page. The geometric patterns are simple, they can be colored even by beginners. As you color, the degree of difficulty increases slightly. Unlike other hobbies, coloring is quite physically and mentally demanding. At the same time, it requires a high level of concentration. In these respects, color is similar to yoga, which offers the dual benefit of relaxation and single-task sustained attention. The spaces you have to cross are pretty small, so you can easily go over the lines, and eraser touch-ups can leave unpleasant marks. With time, however, you will learn to respect the contours better, and constant manual exercise can have beneficial effects on dexterity. These are just a few of the ways coloring can help improve certain aspects of your life. In addition, coloring does not require major investments, and the pencils and the coloring book have the advantage that they can be transported anywhere, easily. Sit back and relax as you color these amazing illustrations!
