You have done a terrific job. I think it looks great with your couches. However, like others, I would find it impossible walking on it. I would tiptoe all around, even jump over the couch to avoid stepping on that quilt.
Be forwarned------ IF you buy that rubberized backing to go under the quilt so that it doesn't slip around, IT WILL DISCOLOR your hardwood floors. Several of my floors are badly discolored even without that backing---just because they have been under the dining table for 15 years or so. You will have to find a rug of the same dimensions when this one needs to be replaced or the color difference will be pretty obviouis.
