Moldings, also called "trim work," are both functional and decorative in your home. Although they give a room distinctive style and detailing, they also serve a purpose. Trim work hides the joints between walls and floors, ceilings, doors, and windows that have been left exposed by rough carpentry and building techniques. Many different patterns and styles of trim work are made from a variety of softwoods and hardwoods, so the most important thing is finding trim work that is going to best match the overall design aspect of your home. If you're feeling creative, these woods can be used in combination as built-up-moldings to create intricate patterns in your trim work design.
