Which side of posterboard do you use?

When using posterboard for a project, it is important to consider the finish of the board. Posterboard typically has two sides: a glossy side and a matte side. The glossy side is more reflective and vibrant, making it ideal for projects that require a high-quality finish or vibrant colors. The matte side is less reflective and is better suited for projects that require a more subtle or muted look. Ultimately, the choice of which side to use depends on the desired aesthetic and purpose of the project.
