Where would you find fabric for making tablecloths?

In the home decor section of a dedicated fabric shop. You can ask a store employee to help you find the proper fabric if you aren't sure what type of fabric you would like to use. Unfortunately, stores like Walmart that carry some sewing supplies will have cotton and flannel for making clothes and quilts (depending on the store) but won't have the specialty fabric like what you would want for a tablecloth.
