Let's say you want a single panel across a particular opening because you want a seamless view instead of 2 panels where you might have a doorway seam right in the middle of your line of view. Or, perhaps you just don't want to unsnap a single panel every time you want to draw your curtain. We came up with the following technique that was sometimes used when clients wanted to keep the vulnerable netting away from prickly stucco that we call the "stucco strip".
A stucco strip is simply a 3" or 4" heavy webbing that can be thought of as a mini panel. One edge of the stucco strip is marine snapped to the wall and the other leading edge can be rigged as a doorway using a fiberglass rod and magnets, just like any other panel to panel doorway. The magnets separate easier than the marine snaps and you have a magnetic doorway close to one edge of your opening where it is less noticeable. The downside to a stucco strip is that after you've drawn your curtains, the 3-4" stucco strip remains on the wall. The cost for a stucco strip is $30. You will also need to purchase any rigging hardware (fiberglass rods, magnets & marine snaps).
If your panels turn a corner, elastic cord will be very important for stablizing your curtains in the wind. Elastic cord is used as a rib when stretched vertically between two D-Rings like a giant rubber band and will brace the curtain under windy conditions. Elastic cord is very useful at the outer corners when a curtain panel turns a corner inside a corner column to add structure.
The vertical elastic cord gives the curtain panel something to go around as it turns the corner providing a nice crisp edge and helps to maintain horizontal tension along the base. Elastic cord can be used at any column which are not necessarily corner columns or even where there are no support columns at all to act as a rib to brace the curtain.
They aren't expensive, and if you find you don't need it? Well... who couldn't use a giant bungee cord to shoot potatoes over the back fence?
