10x Better Than Expected

[This review was collected as part of a promotion.] I was pleasantly surprised by these curtains! I got the to replace the ones I had that were “black out” but still let light through. Put these up and I was shocked at how dark they actually made my room. They are light weight, easy to hang up, are easy to maneuver. They actually block the light without being super dense or heavy and so far have stood the test of my cat trying to climb them. I will be getting more to replace curtains in my other rooms as well!

Zero light from outside

[This review was collected as part of a promotion.] The best curtains I've ever had! They truly block out the light from my windows, the fabric is thick and provides excellent heat protection, and they look amazing because their sand color perfectly complements my home decor. Very good quality and functionality; I highly recommend it.
