Test Roller Cover's Directional Movement

What happens here

To determine the correct orientation for your paint roller cover, hold the roller cover in both hands. Apply gentle pressure and roll it between your palms, mimicking a painting motion. Observe which direction the cover tends to "walk" or move along its length. The video demonstrates that rolling in one direction causes the cover to move down or away from your body, indicating it would loosen on the frame. Then, reverse the rolling motion to see the cover "walk" in the opposite direction, tightening up. This test helps identify the natural friction-based movement of the cover.

Goal: Understand the roller cover's inherent friction-based movement to prevent it from slipping off the frame.
