You are looking down into a paper grocery bag. At the bottom are an assortment of screws, mounting hardware, switch plates, towel bars, escutcheons, and more (some have been pulled out of the bag already).
When I get ready to hang wallpaper, I “undress the room” … meaning, I remove light fixtures, towel bars and toilet paper holders, light switch plates, window treatments, mirrors, etc. I set all the hardware and screws that go with these items near the spot where they will be reinstalled, with all these elements in a certain order, and collated to their respective holes and fasteners and brackets, so it will be simple for me to put everything back in its place, once the paper is up.
But on this job, the wallpaper had to be sent back due to a defect, so it was a couple of weeks before the new paper arrived and I was able to return to finish the job.
In the meantime, the homeowner, understandably, wanted a tidy room, so she picked up these things. And threw them all together into one bag.
Arrrgh!
But not insurmountable. It took a little digging and fitting and futzing, but I was able to sort out what went with what, and I got all the fixtures back in place.
