Show Towels
Towels hung strictly for show or decoration, meant to enhance the beauty and appearance of the bathroom. No one, not even the residents of the home, are allowed to use them.  Guests are also not allowed to use them as they are strictly decorative in nature. Other less decorative towels should always be provided for functional use by residents or guests in a show towel home.  Show towels often feature appliques (such as satin seashells or butterflies), elaborate lace trim, scalloped edging and, at the very least, should color-coordinate with the scheme of the bathroom.  Show Towels are the cause of much debate in online communities.
