Here is what I came up for the glass... (many thanks to sjaaks for the concept) Not perfect, but after several attempts at different methods, I think this is where I will leave it unless I come up with a better idea...
I also used a printable transparent film sheet, but I had a hard time getting a perfect adhesion to the glass. If you look closely, you can see micro bubbles... I also found that the ink was very susceptible to scratching, so I tried different methods of protecting it with either a blank white label sheet (much like the process sjaaks used) and clear laminate film... I couldn't get a solution I like that didn't end up too thick, so I instead switch to spraying the back using a mix of white and silver spray paint... Cutting out the center is the part I found to be the hardest (from a perfectionist point of view). You couldn't see how the cut looked until you pealed off the backing and applied it to the glass, then it was too late to make another cut or trim... You can see a very thin while line along the bottom...
The nice part is it is not hard to lift the glass back out and remove the decal cleanly from the back of the glass, I have done it 7 or 8 times already!
So I may make another attempt if I get board down the road, for now this will do...
