Planning the posts, sills, casing trim, stops and still stops, I divided bigger and bigger areas until, like magic, all the posts and rails disappeared. The 126” width allowed me floor to ceiling with just this 3/4x1.5” stops showing above floor and at ceiling. Corner posts eliminated with 6” radius face and stops. A 12 Ft x 20 Ft porch wrapped in two pieces. The 180deg turf to clouds unbroken view is breathtaking with or fruit, nut and veg forest blaming. Birds dot seem to notice us, building nests just feet away. Humming birds hover outside the corners inches away. This screen is stretchable like a drum head. You can lean into the screen and bounce back like a trampoline. Important - when you have all edges stretched out with no sags, just before adding cap strips, staple screen like every inch. I I used monel staples for longevity.
