I used two different tiles in my home elevator (Grandma’s Doilie Quartet, on the ceiling and Lovers’s Knot as a wainscot). It turned out even better than I had hoped. I was going for an old Victorian hotel elevator look. Between the tiles, marble on the floor, vinyl marble mural on the wall and Chrystal lamp shades bolted to the ceiling, it turned out perfectly.  I did it myself in two days at a total cost of $400 excluding the marble flooring. 
Love, love, love these tiles.
