I bought these panels to replace old pleated fabric shades in master bedroom and bathroom. They worked great for me....I liked how lightweight they were yet lined white so our sun won't bleach the printed fabric over time. Not true blackout panels but enough to let us sleep in on weekends! On nice days, I open the panels to let sunshine in. I did have to cut and hem the bathroom panels to custom fit odd shape windows as the short length was still too long. But it worked out without too much hassle using my iron, ironing board and fusing tape from a fabric shop. These panels were a good buy! Happy with outcome.
Not quite blackout but definitely room darkening. Other curtains from Target have truly been blackout. They look nice but hang kind of lopsided but that may be because of how they were folded for packaging.
