We were looking for curtains with a modern design pattern.  These curtain panels fit the bill perfectly.  Great colors and pattern.  Unfortunately, the "Room Darkening" description of these panels was far from reality.  On first night after hanging them, we experienced a significant increase in light entering our bedroom.  Almost pulled our old worn out curtains from the trash bag and rehung them!  Luckily we searched the internet and found a solution that has worked out well.  We purchased BLACKOUT CURTAIN LINERS.  They are sized perfectly and fit nicely in back of the curtain panels.  The bad thing is we had to spend an extra $65 to remedy a misleading product description.
