We have a Camellia so one end are the sliders to our bedroom, and the other end looks at the neighbors so I found some great and very cheap outdoor drapes that are very long and put them up on the other end. We can keep our windows in the bedroom clear and see out and the neighbors don't catch us with our shorts down. The off white canvasy unlined drapes for outdoors came from IKEA. Two pairs did the trick. And they wash well and we have had them for two years and they still look great. AND did I say they were cheap...Look up IKEA's online catalog if you are interested.
P.S. This was just for the end. The big expanse of back is screened with Odells wall.
Here I think I have the link;
