In normal use, picture hanging cables and cords do not mark walls. Stainless steel cable and nylon cord hang vertically and have little to no contact with the paint surface. Most marks people notice come from the back of the frame rubbing the wall, not from the cable or cord itself.
Why marks ...
You can create a clean, modern display without frames using hardware that grips the artwork or panel directly. With the right picture hanging system, you can arrange prints, posters, photos, and panels in neat rows, grids, or gallery layouts without drilling through the artwork.
Best no-frame ...
