Love that texture.  Thinking outside the box can be contagious and the rewards, remarkable.  Lou Ann's own decaying textured venetian plaster is in homes all over north Alabama.  And for those more demanding clients, a raised stencil over that is a must.

The first four photos below are done with Lou Ann's decaying plaster, glazed and faux water damage was added to help with the illusion of old and decaying.  The color washed ceiling was also included in the water damage effect.

Faux tile, brick, stone and more are also available and come in handy when an area may not be stable enough for the wieght of the real thing.
