Begin by measuring the perimeter of the room where you plan to install the molding to determine how much material you need to purchase. Using a miter saw, cut the molding at the correct angles to fit the room's corners, typically requiring 45-degree cuts.

Once all pieces are cut, use a nail gun to attach the molding to the wall, ensuring to nail into the studs for a secure fit. After installation, fill any gaps between the molding and the wall with caulk. For a final touch, you can paint or stain the molding to match your decor.

This project is easy and can be completed in a few hours, giving your space a fresh, new look.
