Secure Catcher via Creasing (Method 1)

What happens here

With the masking paper hanging from the initial blue tape line, create a distinct crease in the paper just below where it's attached. Fold the paper upwards along this crease, effectively forming a channel or pouch. To maintain this shape, take small pieces of green painter's tape and tack the folded paper firmly to the wall at regular intervals. This method creates a robust, upward-facing barrier designed to catch heavier paint drips and splatter.

Goal: After applying the base paper, create a defined crease in the hanging paper, fold it upwards, and secure it with additional tape to form a deep, effective paint-catching channel.
