Art Alternatives Classic Cotton Black Studio Canvas is made with unbleached 5 oz. cotton duck that is primed with acid-free black acrylic gesso resulting in a final weight of 8 oz. The canvas is stretched around kiln-dried pine stretcher bars and stapled on the back so you can paint on the ¾" profile edges. Classic Cotton canvas works well with traditional painting techniques using acrylic paints and oil paints, and also works well with spray paint, airbrush and mixed media. Black canvas is great with fluorescent, iridescent and interference paints, fluorescent paint markers and more!
