How to stop light from leaking at the top of my curtain?Updated a year ago

Follow these steps to troubleshoot the issue.

If the blackout curtain is on a curtain rod: 

1. Make sure that the fabric of the curtain lies against the top edge of the window frame. In order to block out the light, you will want the fabric to create a backward "L" shape towards the window, as shown below. The best way to achieve this is to place the curtain rod above and close to the window, as most standard curtain rods work well in this regard. You will also want to ensure that the fabric is stretched taut between the magnetic blocks along either yellow line number 1 or 2, as indicated in the photo below.
   
2. If you are using our blackout base layer, be sure every one of the curtain ring holes has a curtain ring used (there are 14 total). Also, be sure the curtain rings are placed on the curtain rod itself (not the fabric tabs of your outer curtain). 
3. We recommend placing the window plates close to the corners and edges to eliminate the most light. If you need to reposition the window plates, we recommend holding the fabric in the places where the window plates will be. This will allow you to determine where the ideal locations are to block the most light.
4. Some window frames are very shallow and may need some additional recommendations. Please reach out to us at [email protected] and we can help fix your light leak issue. A curtain rod that is placed at least 6" above and close to your window will help eliminate light leaks. 

If the blackout curtain panel is used without a curtain rod:

1. The adhesive strips can be placed on any smooth surface. Some windows work best with the window plates attached to the top/inside portion of the window frame, or if you have a window casing the window plates can even be placed on the outside of your window on the wall. We recommend holding the fabric in the places where the window plates will be before adhering them to the window. This will allow you to determine where the ideal locations are to block the most light.
2. To improve the performance of your blackout curtains, try experimenting with the position where the blackout blocks are clipped onto the blackout fabric. It's recommended that you clip the Blackout Blocks close to the seam of the curtain on the top. This will reduce the weight of the fabric in between the blocks and ensure the curtain doesn't droop. Keep in mind that some windows may require more fabric above the blackout block while others may need less.
