Floorcloths are canvas, double primed then painted with whatever design you like. They are hemmed and then varnished with several coats of polyurethane. They are then used just the same way you would a rug. You can make any size you like, room sized or sized for a throw rug. They are great for floors that aren't carpeted, and are very easy to clean. They were widely used in the 18th and 19th centuries before carpeting became affordable.
