Hello! I thought it wouldn't hurt to ask here because I know several people on the forum have serious art training.
Today I found a silk screen on canvas by an artist that I'm very fond of. I bought it for just under $3 at a thrift shop. The print is by Marushka (not particularily valuable but I sure do love it) and is grass silouhettes in brown on the natural canvas....it's a bit stained (the canvas is slightly discolored.) Is this something I can clean myself or should I not even attempt it? If I can do it, how do I?
