Are Sound Waves Able To Penetrate Canvas Painting?

I am planning to use canvas material to cover up some absorption panels. Will this be a feasible idea? Will the surface of canvas able to let the sound waves penetrate through effectively, or will it totally reflect the sound off the surface? I know that an acoustically transparent fabric is the best(I already have them at side walls) but am thinking of some kind of beautiful art at the front wall behind the speakers.

Any opinions or advice would be most appreciated.
