Made with archival-quality natural cotton, this heavy duty canvas is gesso primed so that you can start painting immediately. The medium/rough texture surface is perfect for use with acrylic and oil paints, and the frame is professionally constructed, with medium-weight cotton duck stretched around 1.5" profile kiln-dried stretcher bars and held in place with a flexible spline, so artists can paint on all four edges.
