These were exactly what I wanted.  material is nice weight but you can see through it and space feels private.  I have these on my front porch and you cannot see through them from the outside.  I will be adding weights to the bottom or a way of anchoring them to my columns due to the wind. 
They blend so well to my house that I had two people tell me they didn’t even notice them, although they really liked them when they got close up to the house.
