Step 2: Making the Screen
Starting in the center of one of the long sides of our picture frame, use the staple-gun to attach the edge of the screen fabric. Then, stretch the fabric tight across the frame, and staple it directly opposite the first staple.
Move to the shorter side of the frame, and do the same thing on each side.
Once there is some tension in the screen, slowly work around the frame, stretching and stapling until the whole screen is evenly tensioned, with no weird ripples, bumps, or saggy spots.
Once there is a staple about once an inch all the way around the frame, and the screen is nice and tight, you have an almost completed screen frame!
