Hold the mesh down firmly with one hand.

Use the convex side of the screen rolling tool to press the mesh down into the channels.

The convex disc on one side of the roll bulges outward, and the concave disc on the other side caves inward.

Using the screen rolling tool, press the mesh into the frame channel on all sides of the frame.

Keep the mesh in the same place and stretch it as best as possible so the mesh will end up tight on the frame.
