•Paper Quality: Thicker paper is ideal if you plan to use markers, watercolors, or gel pens, as it prevents bleeding.
•Illustration Style: Choose a book with an art style you enjoy—whether that’s simple, bold outlines for younger kids or intricate designs for adults.
•Binding: Spiral-bound books can allow for easier flipping and coloring on every page, while perfect-bound books (glued) tend to lay flatter when open.
