Maybe because it's been a windy season, and it's quite possible I didn't "do it right", but when it's windy, the shade is so light, it flows with the wind...  Quality of the shade is good, and the hardware works nicely.  But if you live in an area, with any wind, these might not be good for you.  Or, if it's a low hanging curtain, I suppose you could find a way to anchor the curtain, so it does not fly up, this could be a good buy.
