This 10 oz. heavy-weight, raw cotton canvas is ready for preparation with the ground of your choice. This canvas is strong and has a medium tooth, yet heavy body. It strikes a nice balance between lighter and heavier weight canvas. This product works great for staining techniques that involve pouring thinned paints onto the raw canvas resulting in abstract color combinations. Staining achieves a fluid and spontaneous convergence of the image and the fabric, not possible with gesso prepared canvases. Please note that applying oil paints to raw canvas can be caustic to the canvas fibers.
