I see reference to hemp being used in artists' canvases, should almost sell the final art regardless of quality.
Hemp seems to be more durable in all respects, Up to 8 times stronger than linen, and the fibers are as much as 5 times longer than linen.
Hemp was readily available in the past, so one wonders if it was so promising, why it did not get used from the beginning. There could be many reasons, such as it was a strategic material in a naval world, or possibly the processing into fabric is better today.
A lot of the hemp materials available today are 45% cotton, but 100% is available. You could stretch it like a tennis racket string.
