From an architectural perspective, moldings are decorative strips made of solid wood, plastic, plaster, polyurethane, fiberboard, or other synthetic materials that are used to hide or cover surface imperfections, fill up the gaps between walls and the ceiling/flooring, or simply as a means of decoration.
Using decorative moldings in rooms can transform its appeal, thus making them look more grand and unique. These big horizontal strips, originating from the ancient architectures of Rome and Greece, are used at the joints of walls and ceiling/flooring, door or window frames, or even where a pillar meets the ceiling.

Traditionally, they were also used to decorate cabinets and other furniture items. Crown moldings aren't very expensive and can be used to enhance the aesthetics of a room or an apartment in a very cost-effective manner. Let's take a look at some information about crown molds, and installation tips.
The material you choose for crown molding will directly affect its look and durability. The installation procedure also plays an important role. It's always better to choose moldings made of good quality materials even though they may be relatively expensive. The best material is plaster; it is durable and gives the molding a smooth and delicate look. 
However, installing plaster moldings may not be a DIY job and would require the skills of a professional. Other materials such as fiberboard or polyurethane are moderately priced, but do not provide the expected finish and quality.
Moldings made from these materials can be installed easily, and don't necessarily require a professional. However, a DIY would require certain tools like a miter saw, coping saw, caulk gun, nails, and the like.
