I would put them down there
but the walls are concrete block. Too much hassle to put in the plastic nail holders.
So they are upstairs in an empty area of my hallway.
Also FYI, I am accumulating grungy white cleaning towels, basically bleached out shop towels for some pix showing the before and after results using Sears detergent. I plan to organize it similar to how you did your wash featuring the Fuller 86 detergent.
It will be about a month before I dirty all of them up so stay tuned.
