Update 11-9-2020 We have had these up for several months￼. They are exactly what they say they are  they keep out the heat very well￼  the light. The room that we have them in is extremely hot in the summer and extremely cold in the winter￼. Over the summer they helped tremendously! Plus they are absolutely BEAUTIFUL!!!

Put these up yesterday  they are absolutely beautiful! They truly do block out pretty much all light. They are exactly what I thought they would be  wanted! Now I just need to see how much heat they block. (We have a 4 seasons all doorwall room that gets extremely hot in summer  cold in winter- hoping these will help! Once we get hotter weather I’ll post if they work to block heat like I am hoping they will)

ABSOLUTELY  LOVE THESE CURTAINS!!! BEAUTIFUL STUNNING!!!! extremely cold in the winter.
