What is a canvas board made from?

A canvas board is typically a sturdy surface for painting that consists of canvas stretched over a rigid backing, which is often cardboard or similar materials. This construction provides a solid and durable substrate that artists can use to create artwork, ensuring that the canvas maintains its shape and texture while allowing for easy handling and transport.

Canvas boards are a popular choice for both professional and amateur artists because they offer the advantages of traditional canvas but are more lightweight and generally less expensive. The tension of the canvas can help hold paint effectively and provides a reliable surface for various paints, including acrylics and oils.

Other materials mentioned could be used for different forms of artwork but do not represent the common structure of a canvas board. For instance, wood coated with gesso is primarily utilized for wooden panels and does not incorporate a canvas. Soft fabric layered on foam wouldn't have the same durability or painting surface quality, and flexible plastic sheets would not provide the texture or absorbency typically associated with traditional canvas.
