I am making slow progress.
I sorted through a few more sheets, labeling, sorting, and putting pieces in plastic bags. Doing tasks with my left hand which are normally reserved for my right made my left hand start to rebel after about 40 minutes, so that was that for the physical part today.
I also did some research on Second Empire architecture and interior design. It has been more difficult to find information on interiors than exteriors, but I'm forming some ideas.
Meanwhile, hopefully just one more week of this and no further treatment needed!
