We recently moved to house that REALLY needed blackout curtains. Why? Because our huge window in the master bedroom looks on to the patio that has motion light to scare off possible intruders. We have no control over this light as it was put up by the HOA. 

It seriously looked like a floodlight was shining into our bedroom until we purchased these curtains. To be honest, they are the most stylish blackout curtains I have ever seen - and they make our new home look very luxurious. 

I even bought another pair in the grey color for the living room. 

Pros: great price, look expensive, stylish design
Cons: I really don't have any...
