Cut In a Sharp Line

What happens here

After selecting your stiff-tipped brush, dip it into the wall paint, ensuring it's loaded with an appropriate amount—not too much to prevent drips, but enough to make a continuous stroke. Carefully position the brush at the precise joint where the wall meets the ceiling. Using only the very tip of the brush, draw a straight, sharp line along this edge. This technique, known as 'cutting in,' is crucial for creating a clean and defined boundary between the two surfaces. The stiffness of the brush helps to maintain a clean edge, even if the surface texture is uneven or challenging.

Goal: Create a clean, sharp paint line along the wall-ceiling joint.
