Review on Yakamok 100% Blackout Curtains For Bedroom 84 Inch Length, Grey Full Light Blocking Drapes With Black Backing, Noise Reducing Thermal Insulated Grommet Panels For Living Room, 52Wx84L,Gray, 2 Panels by Kristen Barrett

These curtains seem to be made of sturdy material. The metal grommets are also plenty sturdy for the task and look nice. While the material is sturdy and light proof, it's relatively lightweight. I didn't even need to install the middle support on my lightweight curtain rod to help support these, even with the curtain rod near its maximum length.The curtain material is plenty thick to completely block light. I got these mostly to help save on electricity bills by leaving these closed during the day in the summer in a room that gets a lot of sunlight, but not a lot of use during the daytime. These do indeed block the light quite nicely, helping to keep the room from heating up as much from the sun.If you want complete blackout, then you'll want to get shades that are several inches longer than your windows. As you can see from the last photo (daytime, shades closed,) I do get substantial light leakage from the bottom of the shade in my case because the bottom of the material is near the bottom of the window itself. This isn't a problem for me, as I was really only concerned with heat, but if you actually want to make the room completely dark, e.g. for sleeping, then make sure that you have several inches of extra material on every side of the window.As can be seen in the first photo, these shades do come rather wrinkled out of the box. A wash should take care of that, though.
