What is not to love about a floor cloth? I needed a new rug for the living room so I whipped one up *from the stash*--you know that means it was free. I had a length of black and white floral, a pass-along I never thought I'd use, and doubled it was just the right size for my space. I interlined it with a piece of canvas, stitched it on the machine, pressed it, and was done. With my fabric on the top and bottom, I only have to wash it half as many times--the rest of the times I'll just flip it over.
I have only used these when I have a piece of furniture weighing the center down, so I can't answer for a free-floating one. But for anchoring my living room? Yes.
