Hello all! I would like some idea's on what i should put on back of clear plastic windows on a building that has no interior so as to not look so barren. Saw somewhere where where someone put "scotch" tape on back to keep from see through. I have applied the window signs to my "city" clasics bldgs and they look good. So any info/input would be great.(these are plastic, not craftmans's) Anyone? thanks Tommy
