We currently renovating our sun room and attached dining area. It is our plan to wainscot in both rooms. We are having trouble deciding how high to place the boards because we have cathedral ceilings in the sunroom only. We are told normally that they should be placed at 3/4 of your wall height, but what if the highest part of our ceiling is about 11 feet? If anyone has any info. or advise it would be greatly appriacited!
