very good

got to hang on a bedroom closet without a door works great and the material feels nice and thick. I would say get a curtain rod bc I was hanging with a couple screws and some thin heavy duty like rope lol and it's not holding up great but it works for now but eventually will switch it to a curtain rod to look nicer and stay up better

update to these

If you have the old vertical blinds on your sliding door. Time to get this curtain. The visual appeal. The ease of opening and closing. I should of switched years ago. I installed on a 1" rod and it looks great. Well made, it blocks the heat and the light that pours in from the deck. Just a great product. Do yourself a favor and get rid of those 1980 blinds that never close right. That usually has a couple blinds that are twisted the wrong way and make that annoying sound Everytime the wind blows.
