Step 3 -- stretch the canvas very tightly onto the frame and staple into place. The easiest way to do this is to staple the longest side in the middle, then have someone to hold the frame in place while you pull the opposite side tightly and staple in the middle. Repeat top-to-bottom. Then work side-to-side, top-to-bottom, stapling outward from the center as you pull the screen tightly. Try not to allow any "bubbles" to form in the screen. This is tricky -- take your time! Stop when you get near the corners (see photo, above) to allow room to fold and staple the corners.
