Worlds of Wonder: A Coloring Book for the Curious Spiral-bound – January 1, 2020

The Worlds of Wonder coloring book offers intricate and interesting illustrations, ranging from flowers and animals to underwater scenes and houses. The paper is thick and durable, making it easy to color with a variety of mediums including pencils and gel pens. However, it is advised not to use markers as they might bleed through onto the other side of the paper. The spiral-bound design makes it easy to flip through and color, but the spiral-bound spine can cut into some of the pictures. While some customers found the images too small to color, others found the narrow spaces and amount of detail to be perfect for a challenging and engaging coloring experience. Unfortunately, while the illustrations are beautiful, they are printed on both sides of the paper, making it difficult to use permanent markers for coloring without bleeding through onto the other side.
