Help....I'm removing glue/paper residue after stripping 96 yrs worth of painted wallpaper. Although I am using plastic...I cannot tape it to the wall to cover the woodwork as I am stripping the wall. Two sections I've already done....my beautiful 1913 varnished woodwork now has film and splotches on it. I need to preserve this beautiful wood, but not sure how to cover it with the plastic as i cannot secure the plastic. Any suggestions??
