I am an avid gardener, like so many of us on here. But to support my habit, I own a shade sail company. I spent a bit of time trying to find the correct forum on here for this and this looks like the closest. Hopefully people will just search the term.
For those who do not know the term shade sail, it is often known by shade canopy, sun sails, shade structures and "those things strung up in the air that my neighbor has". I have included a link to my company, www.tenshon.com, as a picture or two will likely make you say "oh, thats right, I know what those are." I would be happy to answer any questions that anyone may have on the subject. They are not a fit for every situation, but they can certainly spice up a backyard garden, pool, or deck. Let me know you thoughts!
