Is the fiber content available? Many home dec fabrics are cotton, however, they are often a bit heavier weight than quilting cottons, which may make them difficult to work with in patterns with lots of seams. Bedding might be a better way to go, as lots of folks use sheets for quilting. In any case, I would wash the item first & make sure it survives before cutting it. Another source for inexpensive quilting fabric is used clothing, especially men's cotton shirts.
