Canvas boards are flat, rigid surfaces used for painting and drawing. They are typically made from materials like wood or compressed fiberboard, providing a sturdy base for artists. The surface is often coated with a layer of gesso, which helps paint adhere better and prevents it from soaking into the board. These boards come in various sizes and textures, allowing artists to choose the best option for their work. Canvas boards are popular among both amateur and professional artists because they are lightweight, easy to transport, and can be framed or displayed without additional support.
