sounds like a good concept, but if it comes off easily by moistening with a spray bottle of water, will it come loose in damp, humid weather? Curious to see how it works for you.
I had thought about even using just plain ol' wallpaper, but didn't know how it would stick to the mirrored surface unless you roughened it up a bit.
The other alternative, which I am also considering, is to just hang a lightweight curtain over the mirrors, so that you still have the stability of the doors to keep everything in its place in the closet.
Of course, we don't even have our 5er yet...these are just ideas I'm storing in my head for when we GET it
LOL
Anyway, looking forward to hearing about AND seeing the results of your project! Good luck
