Fredrix unprimed artist's canvas rolls. Although the art of manufacturing artist canvas has changed since the 1800s, the product Fredrix makes today is very similar to the canvas made over 140 years ago. The name was changed (Friedrichs to Fredrix), but their mission has not. Available in the 7oz. ARTIST-SERIES and the heavier PRO-SERIES, 100% cotton duck canvas woven to rigid specifications. Ideal art canvas for artists who need versatility in sizing and the choice to use many different mediums by being able to prime their own canvas exactly as they prefer. For making professional, as well as commercial-grade stretched canvas.
