Sketch paper is a type of paper specifically designed for drawing and sketching. It typically has a slightly textured surface that allows pencils, charcoal, and ink to adhere well, making it ideal for artists. The weight and thickness of sketch paper can vary, but it is generally lighter than watercolor or drawing paper. Artists often use sketch paper for practice, brainstorming ideas, or creating preliminary drawings before moving on to more finished works. It comes in various sizes and can be found in pads or loose sheets, catering to different artistic needs and preferences.
