Is it wrong to use wallcoverings throughout a house?
Yes and No. It is almost always wrong to use patterned wallcoverings in every room. Instead a home that is tastefully decorated will combine paint, paint techniques (faux finish) and wallcoverings. However, not all wallcoverings are patterned. Instead there are wallcoverings that mimic paint and others that mimic faux finishes. These are especially good to use when your walls are not in good enough shape to be simply painted or you do not want a faux finish which is usually difficult to remove or repair. It is then more desirable to use these types of wallcoverings along with an occasional dramatically patterned wallcovering.
