I have already purchased 4 of these in the past and they worked so well, I bought 3 more.  I have put them against my pool fence to hide the view of my neighbor's yard.  I hold them together by using green wire--they do not stand up on their own.  I have read that some people use SPF sun protection spray to stop the sun from fading or bleaching.  I have had mine up all summer and they still look dark green--but I may spray them in the future because I like that idea.
