To use these Crystal Lake Counselor posters and prints, simply find a nice spot on your wall, use nails or adhesive strips to hang them up. When hanging, make sure the surface is clean and flat. For cleaning, gently dust them with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they can damage the print. Keep them away from direct sunlight for long periods to prevent fading. If you need to store them, roll them up carefully and place them in a tube or a flat storage container to avoid creasing.
