Whether a black & white floor is marble, painted wood, or linoleum, I love um! They work in old castles, in 50’s diners, and best of all, in doll houses and doll photography. My version was really simple to create. I purchased four large sheets of 1/4 inch foam board at the local craft/hobby store. Three were white and one was black. This is a whole bunch of foam board, but then I was doing a fairly large area. Two of the white ones were for the base (1/4 inch plywood would also work), while the other two were for the floor itself.
The squares on my floor measure 2.5 inches. A quick search of the web will reveal many fabulous versions of this style of floor. Patterns and sizes vary wildly, so there’s no right or wrong way to create one. You get to choose. I needed a floor that would span my bookcases for my furniture photography, so I broke it into two pieces for easy storage.
Marble comes in many colors. My pink marble floor is made from pieces of Osborne & Little wallpaper, cut up and pasted to a piece of poster board. I like the way the floors add drama and sophistication to my furniture.
