If there is a reason for keeping the wall very quiet, choose a pattern that works all over without pronounced lines...Put very succinctly, architectural effect depends upon a nice balance of horizontal, vertical and oblique. No rules can say how much of each; so nothing can really take the place of feeling and good judgement.
William MorrisHave nothing in your house that you do not know to be useful, or believe to be beautiful.
William MorrisDo not be afraid of large patterns, if properly designed they are more restful to the eye than small ones: on the whole, a pattern where the structure is large and the details much broken up is the most useful...very small rooms, as well as very large ones, look better ornamented with large patterns.
