I looked and looked for something perfect for Master bedroom slider door curtains to block out just a tiny bit more light than the white ones we had up there.  I should have just started with Wayfair!  I found these on sale, and once they arrived, my husband put them up.  Attached is a photo with them closed and then open.  I was trying to match a grey-slate blue color and these nailed it -- perfect match.  Not too much wrinkling -- hope I won't have to take them down and iron them.  I'd have given a fifth star if the material was a little more substantial.
