Go on a reconnaissance mission throughout your house looking for a throw blanket you can steal from the back of a chair or the foot of a bed. If you have a choice, grab one that is either neutral or shows off the colors of fall. Can't find a blanket that will work? In a pinch, I've even been known to use a shawl or scarf. When you score one, lay it over your dining table on the diagonal. You now have a beautiful table covering upon which to build your quick but gorgeous tablescape.
