I have 3 pieces of fused glass that I want to hang on my wall without a frame, and potentially not drilling holes into them, or have wires showing from behind. Ideally I want something that is very unobtrusive. Is there a way to do this? (Pressure screws??) There are two 8″ squares, and 8 X 14″. > I would like to have them away from the wall a bit to allow light from behind. > Thanks for your assistance.
