Maybe I could do the acid wash and then dark stain; perhaps whatever imperfections remained would indeed qualify as 'character'. Believe me, I don't even try to make most things in an old house look brand new. If I use the same stain on the living room AND kitchen floors, that would help them blend together. I don't like high gloss either. Too new looking. I want things to be as nice as possible but still as if they've been gently used a long time.
I think you've solved my wood floor problem, thanks.
Luckily these rooms are an average of 15x15', and the living room/office alcove is even larger. I do love old area rugs on the floor, though. I bought a wool one brand new because I like the pattern, but I plan to throw it over the top of an old swing set frame, water it down, and leave it in the worst summer sun a few days. But I have a number of really old ones. When I used to browse Persian rugs in L.A., it affected me the same as some people browsing jewelry.
BTW, when I was shopping materials to redo the main upstairs bedroom, I couldn't find wallpaper I liked and it was way too expensive anyway. So I watched the online fabric sales and finally located a perfect rose stripe pattern in heavy cotton. Ecru background, red and blue little roses with tiny green leaves, and the stripe borders are pale yellow. I'll put it up with liquid starch, which is a surprisingly authentic method for Vics.
Actual execution of the plan has to await replacement of the ceiling plaster and refinishing of the floor. I don't want to beg trouble.
