**Traditional/Classical Trim**: This style emphasizes simplicity and symmetry, with clean lines and subtle details. It befits spaces with a timeless, elegant ambiance, like colonial or Victorian homes.

Enhance your traditional trims with rope caulking – a classic technique involving running a continuous bead of caulk along the wall-window interface. This method hides tuaft lines and accentuates the trim's presence, evoking a casual, homey charm. Conversely, beveled trim employs mitered cuts at 45-degree angles, slimming down the appearance and providing subtle highlighting.

**Modern/ Contemporary Trim**: For homes embracing minimalist aesthetics, modern trims provide simple, clean lines with minimal ornamentation. They emphasize form and function, often utilizing metal or sleek painted wood to match the surrounding decor. A popular choice is flat, square-stock trim mitigating distractions and promoting a crisp, streamlined look.

Bullnose Trim & Quarter-Round Trim
