I am very pleased with these curtains.  Another customer reviewer said that they were soft and silky with a slight sheen.  That convinced me to buy them.  They are very soft and silky, especially for a "blackout" type curtain.  They are rated as a 3 on the darkness scale.  I would say they are more of a 2 1/2 though 4 being complete blackout.  For me they are perfect for my use as I already have a blackout blind.   I actually like that they let some light through the material,  it shows off the damask pattern.  I selected the Sundress colour which is a perfect shade of yellowy gold not too bright it mixes well with other shades of yellow in the room.  I believe they also come as a set of 2.
