The topic at hand refers to a specialized type of art supply designed to be used with water-based paints. These books typically feature outlines printed on paper that is thicker and more absorbent than standard paper, better suited to handling the application of wet media. The heavy paper stock minimizes bleeding and warping, providing a more satisfying painting experience. An example would be a book with floral designs printed on 140lb cold press watercolor paper.
Using appropriate materials facilitates artistic expression and improves outcomes. The utilization of such a book allows artists, both beginners and experienced, to practice and develop their watercolor skills without the expense and commitment of purchasing individual sheets of paper. Historically, artists often prepared their own paper surfaces, but pre-printed books offer convenience and accessibility to a wider audience, thus promoting creativity and artistic exploration.
