Curtain hooks are used for tracking attachment when they are inserted into the top curtain binding and loop through carriers that slide back and forth through the track channel. An eye-screw inserted into your porch structure combined with a curtain hook is perhaps the strongest method of securing the curtain.
The curtain hook is a drapery pin shaped like a swan with a 1-inch spike that slips between the seam of the 1-inch doubled-over binding. Loop the hook into the eye of the screw and pinch the hook closed.
Curtain hooks are highly versatile and easy to use since they can be easily removed and repositioned. You will receive plenty of these curtain hooks and eye-screws in your kit and they are perfect for securing the 2 upper corners of Velcro attached curtains.
Awnings - Curtain hooks are often used as the only top attachment device for awnings with canvas covers that tie to a metal frame. The ties make Velcro and tracking attachment impossible. Instead, curtain hooks are inserted into the top binding and the hooks loop through the ties that hold the canvas awning roof to the frame.
Positioning hooks avery 2 to 3ft is generally sufficient. The photos below show an 8ft wide panel that is secured at the top using only 3 hooks and eye-screws.
