We have 8 foot ceilings, dark wood trim and wondering if crown molding will help or hurt the resale value? There is so much dark wood throughout the house it is like a cave. If we put in crown molding, what would be a good width size to put up and since everything is dark wood and it is a 30 year old house, would it look strange to put up white crown molding or better to use dark molding or none at all and then use chair railing instead. Thank you for your help. Tammy Gaede
