Many thanks Eric, I will give it a try.
I have just read: Wall Coverings* allow for multiple materials applied to a wall segment or a whole room using the Wall Covering panel. *Available in the Home Designer Interiors, Home Designer Architectural, and Home Designer Pro.

so that's probably why I am having difficulty using the basic SUITE
