When I was a volunteer at Baltimore's B&O Railroad Museum, I learned about antimacassars. These are small pieces of cloth placed over the backs or arms of chairs, or the head of cushions on a sofa or chair, to prevent soiling of the fabric from hair oils. They used to be cloth, or sometimes clear plastic, when I was riding trains in the 1950's. Now they are often paper.
I learned the name comes from Macassar Oil, popular with men in Victorian and Edwardian times. Of course railroads would use them to protect their seats.
After painting the seats in my Amfleet coaches, someone, I think laughingly, suggested I cut small pieces of labels to make antimacassars. I dismissed the idea, until I saw that Keil-Line Products actually makes O gauge antimacassars, complete with RR logo. I had to try them. Bought two sheets of Amtrak and one of B&O, 90 antimacassars per peel-and-stick sheet.
Well, now I'm not sure. This may be just too tedious for 73-year-old fumble fingers to deal with. Maybe I'll do a few rows, then put the coach together with passengers to see if enough shows through the windows to make a difference.
I imagine some on here have done this already. Care to share your results and comments?
