I went into a friends powder room and she did the most creative things with a snaffle bit, stirrup and such. I don't remember the TP holder but I think it was standard. Go to a tack exchange and pick up some inexpensive tack and clean it up and mount it to the wall to hold towels and hand towels. Cheap, easy AND authentic.
I do custom orders (many designs similar to Horse & hound) like this. I can do toothbrush holders, tumblers, lotion pumps, tile, anything porcelain. Items average $5-$10 each. All orders are custom, you pick the design.
