I have a lanai here in Florida that had 8 foot windows all down one side. During the day I love for them to be open so I can watch my butterfly garden, but at night I want some kind of shade to pull down for privacy.
Since I do live in the tropics, I thought wooden blinds would be perfect for this area. I found a great place called Wooden Blinds Direct and they have high quality with great prices. The picture shows what I am looking at. And right now they are offering specials on certain blinds.
Be sure to check them out for your shade requirements.
