I guess all of us know that stretched canvas is one of the most durable supports. But I want to know if canvas boards (canvas pasted on a board) are still ok to use or not in the initial years of training.
Stretched canvas in the markets is very expensive compared to canvas boards (almost double). buying a canvas roll, getting stretchers and stretching the canvas are not easy. Whereas, framing a board at framers is easy and comparatively cheaper (including the cost of canvas).
Are these canvas boards good enough for 50-70 years at least?
