These curtains do not hang “square”. I bought them despite earlier reviews saying individual panels were different lengths.  

I bought 2 panels and they are basically the same length (I measured because it didn’t look it) but they don’t hang evenly.

The curtains darken the room, check.

I’ve got furniture below the window with these curtains and you can’t see that the ends are crooked. So, it works. For the price, I’m satisfied.
