I'm still working on it. I used 60" material and seamed it together at the center. With the hems along the sides it is now about 9 1/2 feet wide,so it hahgs over the ends of the track about a foot at each end.It extends * feet out to the front. I sewed a sleeve along the back edge and inserted a 3/8 piece of rope to fit the track. Have isserted a Fiberglass rod from an old tent to maintain the arch at the front. Here's a frontal shot.
