Hi Armywife: Welcome from Oregon. The backing is usually, not always, sold separate from the top and binding. Usually the company that sells the kit also sells coordinated fabric to go with it. Since your not within easy driving distance (LOL), I would recommend that you find a supplier that has both so you only have to order once and you can be sure the colors match. Another possibilty is using blankets or sheets for the backing. There is some disagreement about using sheets but I have and have been happy with the results.
