Asked the owners at the closing today what their walls were made of,
and they said - plasterboard, which, as I read right now, is the same
thing as drywall... So, if they're correct, why on earth would they
put cheesecloth over drywall???

Anyway, we're going to try to pull some wallpaper/cheesecloth stuff off
to see what's behind it... Somehow it seemed like such an easy
project, and now I'm dreading it.
