just got back from Michaels, having my Tauriel and Legolas canvases framed and the guy mentioned that canvases will fade like prints. Is this really true for these types of canvases? I never heard it before, so I decided to get UV glass on top of my canvases just to be sure. Any other opinions on this cause I have 2 gallery wrapped canvases from Jerry and now I'm worried they will fade if I don't have UV protection on them.
