1. Pull out the old spline and remove the old screen. Cut a new piece of screen about 4 in. wider and longer than the old one. Also cut four pieces of new spline, making each a couple of inches longer than the sides of the frame.
2. Clamp the screen to one long side of the frame. On the opposite side, roll the spline into the groove, stretching the screen as you go. Remove the clamps and add spline on the other side. Repeat the process on the short sides.
