I don't think I understand what you mean. The dust appears to be falling from above and not from the basement since the dust is red and the basement bricks are painted white. And if the source is above, I can't see the bricks because they are behind drywall.
To further clarify, the way the dust lays upon the wall and floor, its as if someone had poured dust down the wall. So from floor to ceiling in those spots there are signs of dust.
How would I use the paper?
